Description

The utility model relates to aviation technology, namely, to the glazing of the cabin in the form of a lantern.

In aviation, a lantern is a transparent part of the pilot's cabin, which protects the crew and passengers from the effects of oncoming air flow, weather conditions, noise, from the effects of a collision with birds and ensures that the crew observes the outside space.

Modern aircraft use flashlights made of plastic, or glass, or other transparent materials, or their combinations, streamlined in order to minimize drag. (“Lantern (aviation).” Material from Wikipedia, the free encyclopedia. Https://ru.wikipedia.org/).

However, these lights do not provide a view directly below the plane and do not provide a sufficient view back, since the transverse size of the fuselage of the aircraft is such that the fuselage overlaps the view down and back.

In light biplanes, for example, in the AN-2 aircraft, the lantern is made of multifaceted glazing with a binding, in which flat glasses are located in front, from the sides and from above (Brief description of the design of the AN-2 aircraft. Http://aviaclub.ru/planes/ nashi-samolety / an-2 / rleh / glava-i / kratkoe-opisanie-konstrukcii /). Flat glasses are connected to each other with the formation of bulges from the sides for viewing back and down. The transverse size of the AN-2 aircraft is smaller than the transverse size of the lamp at the site of its convex sides, and when the pilot's head is tilted to the bulge of the lamp, the fuselage does not interfere with the view down. (AN-2. Passenger / transport aircraft. Http://flot.sevastopol.info/arms/plane/an2.htm). The disadvantage of the flashlight is the presence of binding in the form of a large number of opaque elements in the joints of flat glasses that make it difficult to see. The streamlined shape of the lamp, compounded by the location of the propeller near it, increases drag, quadratically increasing with increasing speed.

The technical problem solved by the proposed utility model is the development of an aircraft cockpit lantern, in particular, a biplane, streamlined, with improved aerodynamics and improved manufacturability and repair, as well as with improved visibility, including below under the aircraft and behind it .

The problem is solved by the lantern of the cockpit of an aircraft, comprising a glazed hull having front, top and convex side parts, in which the body is streamlined.

The housing is made with glazing, including four transparent elements, two of which are larger in size along a line lying in the longitudinal vertical plane of symmetry of the housing. Each of the two transparent elements of a smaller size is connected to a corresponding transparent element of a larger size along a line conjugated with the line of the upper edge of the housing.

In addition, the housing may have an emergency hatch at the top.

The technical result of the utility model is to provide drag reduction due to the streamlining of the flashlight, as well as to improve the visibility for pilots forward, sideways, backward and downward due to the design of the flashlight either completely re-free or with a significantly smaller number of glasses and opaque elements joints of glasses.

The cockpit lantern is described below on the example of the AN-2 light biplane aircraft or its derivatives, including TVS-2MS and TVS-2DT.

The luminaire housing 1 is made of glazing from two main curved, convex, symmetrical relative to its longitudinal vertical plane transparent parts, hereinafter referred to as glasses 2 and 3. Each glass 2 and 3 is made without binding from a transparent polymeric material (or mineral material - glass, quartz , or from a combination of mineral and organic material) and has a power circuit 4 of metal or composite material along the edge (Fig. 3, 6). Glass 2 and 3 are connected at the junction of the cover plate 5 (Fig. 3) also of metal or composite material. The glazing of the housing 1 has an additional two rear windows 6 and 7 (Fig. 2, 4) connected to the main windows 2 and 3, respectively, along the articulation lines lying in a plane perpendicular to the above vertical plane and the axis of symmetry of the aircraft. Glasses 6 and 7 are connected to glasses 2 and 3, respectively, using plates 8 of metal or composite material (Fig. 4). Moreover, a large area of the side surface of the housing 1 does not have opaque glass connecting elements.

Glazing may include more than four glasses, depending on the technological capabilities of the manufacture of glasses. In any case, two main glasses of a larger size are connected as described above and shown in the drawings.

Also, the housing 1 may have an emergency hatch 9 in the upper part (Fig. 2, 5). The hatch 9 may be made transparent or of metal or composite material.

In the two-seat cockpit of the AN-2 biplane, pilots are arranged in a row, and each has the ability to view one half of the transparent body 1. Each side part of the body 1 is made convex in the form of a blister, made together with the main glass 2 or 3. The blister has dimensions sufficient to accommodate the pilot’s head. The pilot, bending his head into the cavity of the blister, can observe the space below and side-behind the aircraft, as well as the side of the fuselage, since the transverse size of the fuselage is smaller than the transverse overall dimension of the body of the lamp.

In the cross section of a lantern with a maximum transverse dimension, the height Hz of the arc (Fig. 3), the chord of which lies in the plane parallel to the XY plane of the associated coordinate system of the aircraft and the longitudinal vertical plane of symmetry of the hull 1, is at least 100 mm to provide the pilot with a free view of the side hemisphere for its part the fuselage.

The lantern can be made using known blowing or stamping technologies and can be used on biplane aircraft.
