Description

Cover for small fixed wing aircraft

The present invention relates to a cover for a so-called pure glider that does not include an engine, a so-called motor glider that includes an engine, and a light aircraft including a fixed main wing (these are referred to as “small fixed-wing aircraft”).

“Small fixed-wing aircraft” referred to in this application is a concept that combines gliders (including both pure gliders and motor gliders) and light aircraft. In this light aircraft, the main wing is kept fixed to the fuselage during flight. In other words, the helicopter, which bears the main driving force on the rotor blades above the fuselage, is excluded from the concept of this “light aircraft” and thus “small fixed wing aircraft”.

When the glider is not in use, it is necessary to protect the instruments and the aircraft surface from the ultraviolet rays and heat of sunlight so that safe flight is possible when using the glider. In addition, since gliders are not designed for use in rain, they need to be protected from rain and other water drops. In addition, since the surface finish coating is applied to the FRP glider, not only the coating needs to be protected from ultraviolet rays, but also the FRP itself needs to be protected from ultraviolet rays.

In addition, it is necessary to protect the connecting parts and driving parts of the glider aircraft from rain.
Further, in the case of a light aircraft or the like, it is necessary to prevent intrusion of birds, insects, dust, and the like from the inside of the engine, the driving portion, and other gaps.
Also, if there is a sudden rain while parked, it is necessary to cover the entire aircraft quickly.

As described above, there is no problem for the necessity of protecting the airframe surface and the like in a small fixed wing aircraft as long as it can be stored in a hangar or disassembled and stored in a dedicated trailer in the case of a glider. However, if you do not have enough time to store and store in the hangar or dedicated trailer, leave the hangar or dedicated trailer nearby, or if it is troublesome to store or store in the hangar or dedicated trailer, leave it outdoors. In some cases, it may be necessary. In such a case, there is only a method of attaching a cover to the airframe for the necessity of protecting the airframe surface and the like in the small fixed wing aircraft as described above.

In addition, about the cover for aircrafts, such as a helicopter and a light aircraft, the technique of WO2016 / 088821 A1 is disclosed.

Conventional aircraft covers generally have a structure that connects the main wing, the front of the fuselage, the fuselage, the horizontal tail and the vertical tail, and a cover divided into parts corresponding to each part of the fuselage. For this reason, it was a hard work to install each part while considering the front-rear and left-right directions of each part.

Also, the case for storing the cover was generally prepared separately from the cover. In this case, a cover divided into a plurality of parts was folded and stored in a folded state. Therefore, when installing, it was difficult to know which part corresponds to which aircraft part, and it was difficult to understand the front, back, left and right directions. For this reason, it has been common to sew ribbons or triangular fabrics of different colors, such as “green” on the right and “red” on the left, for classification of the left and right wings. Also, while the cover was attached, the case had to be stored somewhere, but the storage location was often forgotten or lost.

In addition, the divided parts must be connected to each other using fixing means such as strings, rubber, hooks, and fasteners (including hook-and-loop fasteners), which requires considerable time and labor for attachment / detachment. . Moreover, since the connection of each part was such a simple connection method, it had a poor structure in which wind was drawn from the connection part and fluttered, or rain entered from the gap. Furthermore, it is common to use various fasteners such as strings, rubber, bands, and hook-and-loop fasteners to secure the cover, and the number of fasteners ranges from 20 to as many as 40. The structure requires a considerable amount of time and labor to attach and detach. Moreover, even if a regular fixing method of the cover is performed, it is weak in the wind, and the customer often uses a fastener such as a string, rubber, or band by himself.

In addition, in the case of a pure glider, it is common to disassemble it and store it in a dedicated trailer, but if you want to enjoy the glider for a few days or need a few days in a competition, disassemble it every day In some cases, the aircraft is parked without being stored in the trailer. In this case, the entire cover must be attached. On the other hand, you may want to cover only the canopy part of the flight for a short time and protect the instruments and resin canopy from direct sunlight and sunlight heat. For this purpose, a canopy cover is used, and the canopy cover is generally mounted even when disassembled and stored in a dedicated trailer. Such a canopy cover was a separate product from the cover for each part of the entire fuselage.

In view of the above-described problems, an embodiment of the present invention provides a cover for a small fixed wing aircraft in which a part for protecting each part of the fuselage and a part for housing these parts are integrated, which has never been obtained before. By providing it, the challenge is to realize a secure installation on the aircraft that does not require a lot of effort even by a small number of people, especially one person, and does not easily fall off even with a strong wind To do.

(10) Tenth aspect In addition to the features of the seventh or eighth aspect, in the cover for small fixed wing aircraft according to the tenth aspect, the horizontal tail is provided near the lower edge of the vertical tail. The vertical tail cover is connected to the rear of the horizontal tail cover and has a bag-like structure that can be covered from the upper edge of the vertical tail cover.

(11) Eleventh aspect In addition to the features of any one of the first to tenth aspects, the cover for a small fixed wing aircraft according to the eleventh aspect has a rod shape outward from a part of the surface of the fuselage. A protrusion is provided, and an opening through which the protrusion penetrates is provided at a portion corresponding to the protrusion, and a slit is formed along the longitudinal direction outward from the edge of the opening. A cylindrical projecting object cover is extended.

Here, the “projection” refers to, for example, a measuring instrument (Pitot tube) that measures the speed of air flow as a fluid around the fuselage during the flight of a small fixed wing aircraft. These protrusions are installed at various positions on the surface of the fuselage, such as near the nose, near the cockpit, or at the front edge of the tail.

(12) Twelfth aspect In addition to the features of any one of the first to eleventh aspects, the small fixed wing machine cover according to the twelfth aspect has a propeller at the tip of the nose. The propeller cover for covering the blades of the propeller is continuously provided at the front end of the front cover.

(13) Thirteenth aspect In addition to the features of any one of the first to twelfth aspects, the cover for a small fixed wing aircraft according to the thirteenth aspect has a stretchable outer and lining bonded together. The outer surface is formed of a waterproof and weather resistant material, and the lining is formed of a durable and breathable material.

(1) 1st aspect According to the structure of the said 1st aspect, there exist the following effects.
In other words, by providing a cover for small fixed wing aircraft that integrates the parts that protect each part of the fuselage and the parts that store these parts, which has never existed so far, even a small number of people, especially one person It is possible to realize a reliable mounting on the airframe that does not require labor and that does not easily fall off even with a strong wind.

In particular, once the front / rear / left / right positioning is performed with each part stored in the first place, the front / rear / right / left orientation of the part protecting each part is uniquely determined, so that the position and direction of attachment may be lost. Disappear. Further, since the parts for storing the respective parts are also integrally formed, the case referred to in the prior art becomes unnecessary, and the worry of forgetting or losing the storage place is eliminated in the first place.

Also, the main wing of the glider is as long as 15 to 20 m (7 to 10 m for one wing), and if it is a competition glider, the wing on one side can be as long as 15 m. In the past, it was common to put a bag-shaped cover from the tip of the bag toward the base, for example, it was an image of wearing long socks, and it took considerable time and effort to attach and detach, but this book In the aspect, the cover can be attached to the main wing simply by extending from the base side of the main wing toward the tip, and a great reduction in labor can be realized.

Moreover, since it is not necessary to connect each part with a fastener afterwards, the labor for attachment / detachment is greatly reduced, and wind does not blow from the connection part or rain does not enter. Also, the number of fasteners can be greatly reduced.
In addition, there is no need to prepare a conventional canopy cover that covers the canopy.

(2) Second aspect In the conventional cover, the back side (lower side) of the main wing is in a state where the fabric hangs down due to gravity along the length of the main wing, and the structure is inevitable to flutter with the wind. It has been common practice to twist strings, rubber or belts so that they do not flutter with the wind.

However, according to the configuration of the second aspect, in addition to the effect of the first aspect, the force inserted by the rubber inserted along the edge formed in the arch shape to return linearly is utilized. The fabric tension and fit can be achieved on the lower surface of the main wing. As a result, it is possible to significantly reduce the time and labor required for attaching / detaching the cover by putting the string, rubber or belt after the attachment.

(3) Third aspect The glider's main wing usually has a total width of 15m to 20m (7m to 10m for one wing) between both ends. In the case of such a length, there are cases where the drooping of the fabric due to gravity cannot be sufficiently prevented only by the rubber inserted at the edge.

In such a case, according to the configuration of the third aspect, in addition to the effect of the second aspect, an arch starting from at least one fixing means (for example, a buckle) is formed. And it becomes possible to prevent the bending by the dead weight on the lower surface side of the right wing.

(4) Fourth aspect Conventionally, the lower part of the cover of the body part is formed in a straight line and is generally fixed using a large number of strings, rubber, bands, hook-and-loop fasteners, and the like. Therefore, considerable time and labor are required for attaching and detaching the cover. Moreover, when there was a strong wind, there was a risk that the wind would blow in through the gap, causing the flap to hurt the aircraft or remove the cover itself.

However, according to the configuration of the fourth aspect, in addition to the effects of any one of the first to third aspects, an arch starting from at least one fixing means (for example, a buckle) provided on the fuselage is provided. Since it is formed on the lower surface, it can prevent bending due to its own weight on the lower surface side of the fuselage, making it possible to give fabric tension and fit, and at the same time, damage to the aircraft due to wind blowing and flapping, and removal of the cover Can also be prevented.

(5) Fifth aspect Conventionally, when the front edge and the rear edge of the lower surface side of the covers of both wings are to be connected by fixing means such as a buckle, When it is going to connect with the fixing means, such as a buckle, it was difficult for the operator located in one side to grasp the fixing means on the other side. Therefore, it is necessary for the worker to go under the main wing or the fuselage and search for and grasp the fixing means on the other side. Or it was necessary to have the fixing means on the other side be presented from the opposite side by an assistant.

However, according to the configuration of the fifth aspect, in addition to the effects of the third or fourth aspect, the guide piece can be pulled from the opposite side to pull the fixing piece, so that even one person can easily attach it. . In addition, as a guide string, for example, it is a string of about 50 cm in length, and at one end thereof is a 5 cm square bag made of a co-fabric of the cover, and a non-absorbent cloth is cut into the bag. It is desirable to attach the stuffed material and tie the other end to the fixed piece so that the guide string itself can easily hang down. By doing this, the bag part acts as a weight and does not damage the aircraft with software, and it is square after installation, so it is easy to wind the string, and it is inserted from the end of the cover in the wrapped state. If you do not get in the way.
In addition, the fixing means such as a buckle is usually made of metal or synthetic resin, but it may damage the surface of the aircraft by hitting the aircraft when attaching or detaching, so the fixing device itself can be covered with a cloth or rubber. It would be desirable to be able to prevent damage to the aircraft.

(6) Sixth aspect According to the configuration of the sixth aspect, in addition to the effects of any one of the first to fifth aspects, the front cover and the rear cover are provided on the bottom surface side of the main wing. It is securely fixed at a position between the leading edge and the trailing edge.

(7) Seventh Aspect According to the configuration of the seventh aspect, in addition to the effects of any one of the first to sixth aspects, the cover of the horizontal tail and the vertical tail can be integrally formed.

(8) Eighth aspect According to the configuration of the eighth aspect, in addition to the effect of the seventh aspect, the rubber inserted along the edge formed in an arch shape tries to return linearly. By using the force, the tension and fit of the fabric can be produced on the lower surface of the horizontal tail.

(9) Ninth aspect According to the configuration of the ninth aspect, in addition to the effects of the seventh or eighth aspect, a ladder is avoided when the horizontal tail is provided near the upper edge of the vertical tail. Since the fixing means is provided at the position, it is possible to prevent the ladder from being damaged by the fixing means such as a fastener.

(10) Tenth aspect According to the configuration of the tenth aspect, in addition to the effects of the seventh or eighth aspect, when the horizontal tail is provided near the lower edge of the vertical tail, The vertical tail can be easily covered only by covering the structure from above.

(11) Eleventh aspect According to the configuration of the eleventh aspect, a portion covering a protrusion such as a Pitot tube that can be installed at various positions on the surface of the nose can be formed integrally with the main body cover. It becomes.

(12) Twelfth aspect Conventionally, a small fixed wing aircraft having a propeller, such as a motor glider or a light aircraft, generally has a structure in which one propeller is covered with a cover. Each propeller cover was a simple fixing means that only tied the base with a string or fastened with a hook-and-loop fastener. Therefore, it takes a lot of time, and rain, dust, and foreign matter easily enter the engine room at the base of the propeller, so that sufficient protection could not be achieved. In addition, insects, birds and small animals invaded through the opening of the engine room and sometimes made nests. In order to prevent these problems, it is necessary to close the opening at the time of mooring or parking, and a sponge-like material or the like is packed separately from the cover, which is complicated.

However, according to the configuration of the twelfth aspect, in addition to the features of any one of the first to eleventh aspects, the portion covering the propeller can be formed integrally with the main body cover.

(13) Thirteenth aspect None of the conventional cover fabrics used stretch fabrics. On the other hand, since conventional stretch fabrics are inferior in durability, weather resistance and waterproofness, they have not been suitable for covers for small fixed wing aircraft used outdoors. For this reason, it was necessary to use a non-stretchable fabric, a sufficient fit could not be obtained, and fluttering due to wind could not be prevented.

In addition, there are many covers that use tarpaulin as the outer material with an emphasis on waterproofness and durability, and some have a total weight of 23 kg.
In addition, there are many covers that use a brushed fabric with a soft texture for the purpose of protecting the aircraft, but it involved a dust or pebbles, which caused damage to the aircraft. In addition, the back brushed fabric has high water absorption and slow drying, so mold often grows on the entire front and back. In addition, since it can only be used after it has been dried in the sun after being exposed to rain, it has often been difficult to handle.

However, according to the configuration of the thirteenth aspect, in addition to the features of any one of the first to twelfth aspects, it is easy to attach with a stretchable fabric. In addition, the waterproofness, weather resistance, durability, and breathability required for the cover are also taken into consideration, and the aircraft can be effectively protected even when it is placed outdoors.

That is, the lower nose opening part 29 corresponding to the part between the two wings of the fuselage to the nose 120, the lower fuselage opening part 39 corresponding to the lower part of the fuselage 130, the lower left wing opening part 49 corresponding to the lower part of the left wing 140, the right wing A right lower wing opening 59 that hits the lower part of 150, and a horizontal lower wing opening 69 that hits the lower part of the horizontal tail 160. These open parts are designed to shrink as much as possible by the force of the rubber inserted in the arched edges to return to a straight line, so that a feeling of fit with each part of the airframe can be obtained. This point will be described later.

(2) Center portion In the cover 10 for the small fixed wing aircraft of this embodiment, as shown in FIG. 3A, the front cover 20, the rear cover 30, the left wing cover 40, and the right wing cover 50 are formed as an integral structure. A bag-shaped central portion 11 for storing these portions is also integrally formed. By adopting such an integral structure, the following advantages can be obtained over the conventional cover.

-Unlike conventional covers, there is no need to place each part on the ground once and put it on the ground to check the correspondence with the attached part and the front / rear / right / left orientation.
-It is not necessary to worry that each part placed on the ground will be skipped on the windy day.
-Easy to attach and detach to the aircraft.
-Previously, the installation work of the cover required more than one person, but even one person can easily perform the installation work.

A detailed example of the central portion 11 is the first example shown in FIG. 3B. The inside of the central part 11 is divided into four regions. That is, the front cover storage area 12 for storing the front cover 20, the rear cover storage area 13 for storing the rear cover 30, the left wing cover storage area 14 for storing the left wing cover 40, and the right wing cover storage area for storing the right wing cover 50. 15. When storing each part, gather the front cover 20, rear cover 30, left wing cover 40, and right wing cover 50 from the tip toward the center 11 at the top of the cockpit 110 (near the base of the main wing). Storage can be completed simply by pushing. Therefore, when storing, it is not necessary to once place each part on the ground like a conventional cover.

3B can have a simple structure in which, for example, one rectangular fabric is sewn to the back side of the cover 10 for the small fixed wing aircraft. That is, by sewing the four corners to the outer surface as indicated by the broken lines in the figure, it is possible to form a rectangular pocket having a total of four mouths on each of the four sides on the back side of the cover 10 for the small fixed wing aircraft. Thus, it is difficult for the stored parts to escape to the outside because the pocket mouth is narrower than one side of the rectangle. Note that it is desirable that the end of the fabric is folded back and reinforced in consideration of repeated loading and unloading.

Inside the central part 11, the four parts of the cover 10 for the small fixed wing aircraft are respectively stored in storage areas as indicated by broken lines other than the four corners in FIG. 3B. The display of these storage areas roughly indicates an area where each part is supposed to be stored, and is not partitioned inside. In addition, considering the volume of these four parts, it is good also as partitioning an inside by sewing with the broken-line part in a figure so that it may sort with arbitrary sizes and shapes. The mouths of the four pockets may be simply closed with hook-and-loop fasteners. Further, if the center portion 11 is marked for clarifying the front / rear / right / left directions, the trouble of confirming the front / rear / right / left directions for each part as in the conventional cover is eliminated.

FIG. 4 is a view of the vicinity of the central portion 11 as viewed obliquely from above. When each part is folded from the tip toward the center part 11, it is common and natural to fold and fold the parts so that they have an appropriate size and the lining comes out. Here, since the pocket mouth described above is formed on the back side of the cover 10 for the small fixed wing aircraft, it is folded back so as to be reversed from the folded direction so as to be inserted into the back side of the cover 10 for the small fixed wing aircraft. Need to be pushed into. After storage, the hook-and-loop fasteners 12A, 13A, 14A, and 15A provided on the front side of each part are attached to each other (not shown) of the hook-and-loop fasteners provided on the back side to seal the mouth of each storage area. Stopping the cover prevents it from escaping. The advantage of the structure shown in FIG. 4 is that there is no risk of rain entering the central portion 11 in the mounted state because there is no entrance pocket in each storage area on the surface of the small fixed wing cover 10.

In the second example shown in FIG. 5, the square central portion 11 is stitched to the front side of the small fixed wing cover 10. The central portion 11 is sewn to the cover 10 for a small fixed wing aircraft at a broken line portion in the figure. In this example, unlike the first example shown above, each part folded and folded so that the lining comes out to the front can be pushed into each storage area and inserted without being inverted in the same direction. Therefore, it is an advantage that it can be pushed in by a natural and intuitive operation. It should be noted that the four insertion openings can be sealed with a hook-and-loop fastener or the like. By folding in this way, the size when folded is approximately 1 m square. From this state, it is convenient to carry if it is folded in half, folded in three, or rounded into a cylindrical shape and fastened with a band or stored in a cylindrical case.

In the third example shown in FIG. 6, only the front cover storage area 12 is formed on the back side of the cover 10 for the small fixed wing aircraft, and corresponds to the other rear cover storage area 13, left wing cover storage area 14 and right wing cover storage area 15. The fabric of the portion to be stitched is stitched at the portion indicated by the broken line on the front side. It should be noted that the four insertion openings can be sealed with a hook-and-loop fastener or the like. By doing so, there is no risk of rain entering the front cover storage area 12 in the state where the small fixed wing cover 10 is attached. As will be described later, the first step of mounting the cover 10 for the small fixed wing aircraft is to mount it on the nose 120, so that it is possible to easily identify the front without a mark indicating the front. There is also. In this example as well, the size when folded is approximately 1 m square. From this state, it is convenient to carry if it is folded in half, folded in three, or rounded into a cylindrical shape and fastened with a band or stored in a cylindrical case.

(3) Mounting Procedure Hereinafter, an actual mounting procedure of the small fixed wing cover 10 of the present embodiment will be described with reference to the drawings. The procedure described below is the same in any of the first to third examples of the central portion 11 described above.

As an initial procedure, as shown in FIGS. 7A and 7B, the central portion 11 in which each part is accommodated is set on the cockpit 110 with the direction corresponding to the nose 120 facing forward. At this time, if the setting direction is correct, after that, it is only necessary to pull out and attach the cover corresponding to each part of the airframe without losing the front / rear / right / left direction. The operation of placing the part and confirming the part and direction becomes unnecessary.

When the central portion 11 is set in the correct direction, the front cover 20 is then pulled out from the front cover storage area 12 as shown in FIGS. Then, the pulled forward cover 20 is extended forward, and the tip of the nose 120 is completely covered with the front cover 20 as shown in FIGS. 9A and 9B. At this time, the front cover 20 can be attached to the front end of the nose 120 without a gap by pulling the central portion 11 remaining in the lump so as to be shifted backward. At this time, the position of the central portion 11 is as shown in FIG. 9A. Note that the rear extension 25, which corresponds to a portion of the front cover 20 that turns to the lower side of the blade root, hangs down by its own weight, but this portion is connected to the rear cover 30 later.

Next, as shown in FIG. 10, the rear cover 30 is pulled out. Here, a front extending portion 35, which is a portion connected to the rear extending portion 25 under the blade root, appears.
Then, by closing the front fastener 24 of the rear extending portion 25 and the rear fastener 34 of the front extending portion 35 under the blade root, as shown in FIG. Will be concatenated.

FIG. 12 shows the state immediately before this connection in a side view slightly downward. Before the rear cover 30 is deployed to the rear of the fuselage, the front fastener 24 and the rear fastener 34 shown in FIG. 12 are closed, and then the fixing pieces 22A of the main wing lower buckle 22 are joined to the main wheel 135 at the bottom of the fuselage 130. It is made to stop behind (refer FIG. 13). This order may be reversed.

FIG. 13 shows the position where the main wing lower buckle 22, the front fastener 24 and the rear fastener 34 are fixed from the lower rear side of the fuselage. The position behind the bulge of the tire house that houses the main wheel 135 is a position where the main wing lower buckle 22 is locked. The rubber works along the arch line of the edge 21 connecting the main wing lower buckle 22 and the position just before the front wheel 125 (see FIG. 11), and the force that pushes down the fabric works, giving the cover a tension and fit. . In addition, since the fastener is located under the main wing, there is no fear of rain entering from this gap.

Next, as shown in FIG. 14, the tail wheel buckle 33 is stopped immediately after the tail wheel 175 under the vertical tail 170. When attaching the tail portion of the rear cover 30, either the vertical tail cover 70 or the horizontal tail cover 60 may be used first. In any case, considering that rubber enters the edge 31 of the rear cover 30 and is pulled forward, it is better to stop the tail wheel buckle 33 immediately after the tail wheel 175 as described above. By doing so, since the fabric is not pulled forward, it is possible to attach to the tail and fasten it without applying unnecessary force.

Then, as shown in FIG. 15A, the vertical tail cover 70 is attached to the vertical tail 170. In the left side surface covering portion 73 (located in the drawing on the other side of the vertical tail 170) that covers one side (the left side surface in this embodiment) of the vertical tail 170, the rear end portion is formed in a bag shape. The ladder 173 provided at the trailing edge of the vertical tail 170 is wrapped around. This portion is referred to as a ladder covering portion 75. This is a structure that can be easily and firmly attached to the trailing edge of the vertical tail 170 without using any fixing tool, and also provides a fit. A tail wing fastener 72 is provided on the front edge of the ladder covering portion 75 and the rear edge of the right side surface covering portion 74 covering the other side of the vertical tail wing 170 (right side surface in the present embodiment). As shown in FIG. 15B, the vertical tail 170 is closed on the right side. Although not shown, it is desirable to provide a cover on the fastener so that the tail wing fastener 72 is not exposed and rain does not enter.

Here, when referring to the fabric of the cover 10 for the small fixed wing aircraft, both the outer material 16 and the lining material 17 (see FIG. 15A) need to be stretchable. Further, the outer surface 16 is formed of a polyurethane-based film, and is a material having waterproofness and weather resistance in addition to stretchability, and has almost no fading. On the other hand, the lining 17 is formed of a fabric in which polyester fibers are knitted in a mesh shape. This fabric is also used for sunshades outdoors and is excellent in weather resistance and durability.

Next, as shown in FIG. 16, a horizontal tail cover 60 is attached to the horizontal tail 160. Since the horizontal tail cover 60 is open on the back side (see FIG. 2), the left tail cover portion 63 and the right tail cover portion 64 are simply stretched and stretched in the distal direction. The tip is formed in a bag shape and can be easily and firmly fixed just by covering. Further, the portion corresponding to the blade root on the bottom surface side of the horizontal tail 160 has an integral structure connected to the vertical tail cover 70. In addition, the edge 61 that hits the bottom side is formed in an arch shape as described above and rubber is inserted so that the force works so as to squeeze inward, so you can feel fit just by wearing it It can be installed firmly even in strong winds. The small fixed wing machine 100 shown in the figure is modeled on the ASK 21 as described above, and the vertical tail 170 slightly protrudes from the upper surface of the horizontal tail 160. Therefore, a ladder cap 65 for covering this portion is connected to the horizontal tail cover 60 (see FIG. 18). Accordingly, the position of the horizontal tail cover 60 itself is fixed, and rain intrusion from the gap above the vertical tail 170 is prevented.

When the attachment of the cover to the vertical tail 170 and the horizontal tail 160 is completed, as shown in FIG. 17, the fuselage central buckle 32 is stopped, and the attachment of the rear cover 30 is completed.

In addition, since the pure glider has a feature that the width of the fuselage 130 is narrow, the lower fuselage opening portion 39 (see FIG. 2) cannot be made too large. Further, the length of the body 130 differs depending on the model. Therefore, to prevent the aircraft from raining, the fuselage lower open part 39 is made as small as possible, and rubber is inserted into the arched line along the edge 31 connecting the starting points to maximize the downward force of the entire fabric. In order to exhibit, the starting point distance and the arch angle are important. In this case, since the starting point under the main wing (ie, the main wing lower buckle 22) and the starting point immediately after the tail wheel 175 (ie, the tail wheel buckle 33) are long and the fuselage is thin, a large arch line cannot be formed. A buckle was added at the midpoint and the starting point was used. This is the above-described trunk central buckle 32. Note that the number of starting points to which a buckle should be attached varies depending on the model.

16 to 18 described above are the structures of the horizontal tail cover 60 and the vertical tail cover 70 suitable for the type in which the horizontal tail 160 is installed above the vertical tail 170, for example, ASK21. As described above, even an integrated structure can be easily mounted and fixed firmly. In addition, no fixing means such as a buckle is used in this portion.

Note that a modified example in the case where the horizontal tail 160 is suitable for the type set below the vertical tail 170 will be described.
Here, as shown in FIG. 19A, a Pitot tube 180 may be provided at the tip of the vertical tail 170. The Pitot tube 180 is a velocity measuring instrument that measures the flow velocity of the fluid outside the aircraft during flight. Since the Pitot tube 180 is a fixed structure, it is particularly necessary to attach a cover to this portion. A conventional cover is formed as a cylindrical (cylindrical) cover, and a tag is generally attached prominently so as not to forget to take it off during takeoff. However, if it is integrated with the cover of the aircraft, there is no worry of forgetting to remove it. However, if it is formed into a complete cylinder, it must be taken in and out from one end of the cylinder, so mounting is difficult. Further, if force is applied to the tip during mounting or the cover is displaced, the Pitot tube 180 may be damaged.

Therefore, as shown in FIG. 19B, a pitot tube cover 76 that is integral with the small fixed wing cover 10 is provided. That is, it has an open structure in which a slit 76A is inserted on the lower side along the longitudinal direction. Since only the tip is formed in a bag shape, the Pitot tube 180 can be covered only by covering the slit 76A. In FIG. 19B, only the Pitot tube cover 76 is shown independently, but actually, a fixed edge 76B drawn as an open end is sewn to the tip of the vertical tail cover 70 (FIG. 19B). 20).

The Pitot tube 180 may be provided not only at the tip of the vertical tail 170 as shown in FIG. 19A but also at various parts such as the leading edge of the main wing and the nose 120. In any of these cases, the Pitot tube cover 76 having the above-described structure can be provided at a corresponding portion of the cover 10 for the small fixed wing aircraft. Even when a rod-like protrusion such as an antenna is provided instead of the Pitot tube 180, it can be covered with the same structure as the Pitot tube cover 76 having the above structure.

Again, FIG. 20 shows the structure of the small fixed wing aircraft cover 10 for the aircraft with the horizontal tail 160 on the lower side.
In this case, the vertical tail cover 70 is formed in a bag shape, and can be easily mounted by covering the vertical tail cover 170 from above. In this case, no fixing means such as a fastener as well as a buckle is used. The pitot tube cover 76 is attached to the pitot tube 180 as described above. Here, although the lower part of the vertical tail cover 70 is in an open state, as shown in the circle in the figure, only the lower corner part is formed into a bag shape of about 5 cm, and this is hooked on the lower end corner of the vertical tail part 170. Therefore, it is possible to prevent the wind from rising up.

Note that the vertical tail cover 70 is divided into the front and rear sides on the lower surface side of the blade root of the horizontal tail 160, and the front and rear edges thereof are preferably fixed by some fixing means such as a fastener, a hook-and-loop fastener, and a buckle. In the figure, a structure in which the tail fastener 72 is connected is shown.
The structure and mounting method of the horizontal tail cover 60 are the same as those described above with reference to FIGS.

Finally, as shown in FIG. 21A, the left wing cover 40 is pulled out from the central portion 11 and attached to the left wing 140. That is, by extending the left wing cover 40 from the wing root toward the wing tip, hooking the bag-like portion 43 (see FIG. 1) at the tip to the wing tip, and further stopping the left wing buckle 42 (see FIG. 1) on the bottom side. The attachment to the left wing 140 is completed (see FIG. 21B). The right wing cover 50 is similarly mounted on the right wing 150. It should be noted that the left wing cover 40 and the right wing cover 50 may be attached in either order, or may be attached simultaneously when there are a plurality of workers.

FIG. 22A shows the mounting state of the right wing cover 50 in the right wing 150 from the bottom side. As described so far, in order to be able to form a cover corresponding to each part of the fuselage, it is possible to cover from the top of the main wing by providing an open part (lower right wing open part 59) on the bottom side of the fuselage. The portion corresponding to the wing tip is formed in a bag shape (bag-like portion 53), and the wing tip is covered with this. In addition, the edge 51 constituting the open portion is formed in an arch shape, and rubber having a length of 70% to 80% of the length is inserted. Therefore, in the mounted state, the force that the rubber tries to return linearly is applied to the edge 51, and the action of trying to make the opening portion smaller is generated. This provides tension and fit to the cover fabric.

Note that an arch in the direction of the blade root and an arch in the direction of the blade tip are formed with a single buckle (right wing buckle 52) attached in the middle. If the length of the main wing is not too long, such a buckle is not necessary. However, depending on the length, one or more buckles of an appropriate number of buckles should be used so that they do not hang down due to the weight of the lining and rubber. Necessary. The vicinity of the blade root is continuous with the fabric at the bottom of the fuselage to form an arch shape. However, an integral structure cannot be realized unless the fuselage portion near the blade root is divided and provided with a fixing means such as a fastener, a buckle or a hook-and-loop fastener (see FIGS. 10 to 13).

FIG. 22B shows an arch-shaped mechanism. For example, when a “catenary curve” used in buildings and the like is employed and a uniform arch is formed as shown in the left figure, the force to return straightly becomes almost uniform at any point on the curve.
On the other hand, as shown in the right figure, when a sharp curve shape with a small radius of curvature is formed at both ends and the intermediate part is a straight shape, the force to return straightly is large in the curve shape part. , It becomes weak in the straight part. This means that when the fabric is evenly stretched to give a fit feeling, the structure shown in the right figure causes unevenness in the fit feeling.

Therefore, it is important to form the arch shape of each rubber insertion place as shown in the left figure in order to evenly stretch the fabric with the rubber provided on the edge and give a feeling of fit.

As described above, the installation procedure of the cover 10 for the small fixed wing aircraft according to the present embodiment has been described. However, the procedure after the installation of the front cover 20 to the nose 120, which is the first procedure, is not as described above. Also good. Therefore, this technique is not limited to the mounting procedure.
For example, after the front cover 20 is attached to the nose 120, the attachment to the main wing can be performed first.
However, since the edges of the cover are all formed in an arch shape and rubber is inserted, it will be necessary to work while pulling with considerable force, or the cover will be misaligned and must be repaired later. Therefore, there is a risk that it will not be able to be installed smoothly. Therefore, it is desirable to install according to the procedure described above.

(4) In the case of a small fixed wing aircraft having a propeller FIGS. 23A to 23C show that the propeller cover 27 is integrated with a small fixed wing aircraft 100 having a propeller 105 (for example, a motor glider or a light aircraft). 1 shows a cover 10 for a small fixed wing aircraft.

In the prior art, it has been common to put a bag-like cover on each propeller and fasten the base with a string or hook-and-loop fastener. However, it takes time and effort to install, and there are problems such as rain and foreign matter entering from the gaps at the base.

Therefore, as shown in FIG. 23A, the fabric of the front cover 20 covering the engine room of the nose 120 and the fabric covering the propeller (propeller cover 27) can be integrated. In this way, when viewed from above, the cover is an integral type and there is no gap, so there is no fear of rain entering from above. Above all, it is an advantage of the integrated structure that it can be fixed easily and firmly.

FIG. 23B shows an example of an integral structure including the propeller cover 27. As described above, there is no gap on the upper side, but it is necessary to make a notch on the lower side in order to enable mounting. Therefore, the base portion of the propeller 105 is opened (opening 27A), and a cloth cover is provided to cover the gap. The bottom portion of the front end portion of the front cover 20 is divided into right and left around the propeller 105, the front end is connected to the lower propeller buckle 27B, and both divided edges are connected to each other with a fastener 27C. The tip portion of the propeller cover 27 has a shape protruding from the front cover 20, followed by an opening 27A at the base portion of the propeller 105, and a portion corresponding to the end portion of the propeller 105 is formed in a bag shape. It can be installed just by putting it on the tip. The gap on the back side of the propeller 105 can be easily fixed with a hook-and-loop fastener 27D or the like by covering the cloth as shown in FIG. 23C. Thus, by making the propeller cover 27 also an integral structure, it can be easily and firmly fixed, and rain intrusion and wind blowing can be prevented.

(5) Guide string As shown in FIG. 24, guide strings 22B, 32B, 33B, 42B, and 52B of about 50 cm may be provided on one side of the buckle as each fixing means. Further, approximately 5 cm square bags 22C, 32C, 33C, 42C, and 52C made of the co-fabric of the cover are respectively sewn to the tips of the guide cords 22B, 32B, 33B, 42B, and 52B. These bags 22C, 32C, 33C, 42C, and 52C are packed with chopped dough having no water absorption. As a result, the guide strings 22B, 32B, 33B, 42B, and 52B are likely to hang down, and the buckle can be searched by hand from the opposite side, making it easier to mount the cover alone.

(6) Summary As described above, the elements that are particularly important for the structure of the all-part integrated type small fixed wing aircraft cover that do not exist in the conventional cover are as follows.
A. How to form the open part Location and method of minimum fixing means C. D. Cover edge treatment for fit How to make mold (pattern) This is how the storage area should be.

Of these, A is as described in FIG. 2 and the description thereof. Further, regarding B, as shown in FIG. 2, in this embodiment, it is optimal to use five buckles as fixing means. As for C, as shown in FIG. 2, it is appropriate to insert the rubber after making the edges have an arch shape starting from the buckle. Regarding D, in particular, it is necessary to consider the horizontal tail and vertical tail patterns and the joining method, and there are two patterns, that is, the patterns shown in FIGS. 16 to 18 and the patterns shown in FIGS. As an example, it was shown that a pattern according to the shape of a specific small fixed-wing aircraft can be realized. As for the last E, since there has never been a case where the storage area is integrated, the position and structure are important, and this can be concretely implemented with reference to FIGS. It is presented as a thing.

In addition to the above, it can be easily installed by one person, can be installed in a short time, must not be fluttered by the wind, has high waterproof performance against rain, etc. If it is attempted to satisfy the requirement that it is easy to determine the left and right directions at the same time, it cannot be achieved by only one of the above five elements.
That is, it is necessary to satisfy all of the above five elements and other elements included in the above embodiments as appropriate, but such an idea cannot be conceived from the prior art.

The present invention can be used as a cover for a glider or light aircraft in which the main wing is fixed to the fuselage during flight.
