Description

The utility model relates to aeronautical engineering, mainly naval aviation, and can be used to provide a visual approach to helicopter landing on runways on the runways in difficult weather conditions day and night.

Known glide path indicator ship pendulum (IGMK) NKUG.462519.005, a design sketch of which is shown in FIG. one.

The main elements of IGmk are the body (1), the pendulum (2) and the gimbal (3). The pendulum is a pendant mounting frame (2.1), which is attached to a gimbal (3). A block of lights for the glide path indicator (2.2) is installed inside this frame.

The IGmk housing consists of a welded frame, light panels that are mounted in the left, rear and right planes of the frame, and upper and lower power panels that are attached to the frame in its upper plane and, respectively, in the lower one.

Mounting bolts (4) are placed on the upper power panel (1.1) and a gimbal suspension (3) is attached to it from below, and a pendulum (2) is attached to it, consisting of a suspended mounting frame (2.1) and a block of lights of the BOIG glide path indicator (2.2) .

The gimbal is a cross, one of the axes of which is fixed in the bearings of the bearing housing of the gimbal, and the mounting frame (2.1) is suspended on the bearings on the second axis. BOIG is installed inside the pendant mounting frame (2.1) with the front side facing the front plane of the IGMK (6).

The block of lights of the BOIG glide path indicator (2.2) consists of a frame (2.2.1) and three light blocks (2.2.2, 2.2.3, 2.2.4), which are placed one above the other in this frame.

Structurally, all the light blocks are made according to one scheme: to the circuit boards 2.2.8, 2.2.9, 2.2.10 of the light blocks 1 (pos. 2.2.2) and, respectively, 2 (pos. 2.2.3) and 3 (pos. 2.2. 4) two groups are mounted, the first on the left (pos. 2.2.2.1, 2.2.3.1, 2.2.4.1), the second on the right (pos. 2.2.2.2, 2.2.3.2, 2.2.4.2) of optical light emitters (AIS) based on superbright LEDs (SSD). In the light unit 1 (pos. 2.2.2), the AISs (pos. 2.2.2.1.1) are installed based on the SSD of the first color, for example yellow. In the light block 2 (pos. 2.2.3), the OSI (pos. 2.2.3.1.1) are installed on the basis of the second color SSD, for example, green. In the light block 3 (pos. 2.2.4), the AISs (pos. 2.2.4.1.1) are installed on the basis of the third color SSD, for example, red. AXIs of the first color have aperture angles of light rays equal to α ₁ ° = 2.5 °, green - α ₂ ° = 1.8 ° and red - α ₃ ° = 1.8 ° in the vertical plane and γ ° = ± 10 ° - in horizontal, as shown in FIG. 3.

In each group of AXLs, in the light blocks, an AXL is set in an amount sufficient to provide a given range of visibility, for example, equal to L = 3km for each color. In the prototype, the OSI was installed with yellow SSD Nzh = 24, green Nз = 24, red Nкр = 24.

As shown in FIG. 2, a top view of the AIS of the first groups is installed perpendicular to the mounting plates of the LED blocks, and the second, using special wedges (pos. 2.2.11), at an angle ϕ = 10 ° equal to the given heading angle of helicopter landing.

Light blocks 1 (pos. 2.2.2) and 3 (pos. 2.2.4) have rotation axes. By rotating around their axes, these blocks are installed and fixed using fixation units (pos. 2.2.5 and 2.2.7) so that their light rays are in contact with the light beam of the central light unit 2 (pos. 2.2.3) tangentially, as shown in FIG. 3A.

The central light unit 2 (pos. 2.2.3) has an axis of rotation, which at the same time is the axis of rotation of the entire BOIG. This block (pos. 2.2.3) is installed with its face in the plane of the pendulum suspended mounting frame (pos. 2.1). In turn, the BOIG (pos. 2.2) is installed and fixed using the fixation unit for the angular position of the BOIG (pos. 2.2.6) so that the angle of the optical axis of the central light unit 2 (pos. 2.2.3) is equal to the angle of inclination of the helicopter approach glide path for landing.

The light blocks installed in accordance with the above method and the BOIG as a whole make it possible to form two light fluxes (positions 7 and 8 in Fig. 1), one of which is directed to the IGMK front plane, and the second - at an angle to it, for example, at an angle of 10 hail, as in the prototype.

The IGMP uses the classic pendulum suspension scheme. When the body is swinging, the pendulum will swing. During the trips of the ships on which the IGMK are installed, pitching is present almost constantly. With a large pitching, helicopter flights are not performed and, therefore, IGMK is not used. In this case, the pendulum should be fixed. In the prototype under consideration, the pendulum is fixed using the locking mechanism (pos. 6) in the form of a bolt with a thread on it and in the lower power board, which is screwed into the pendulum until it stops.

IGMK works as follows. Power supply is supplied to the IGMK and, depending on the course angle of approach of the helicopter, the left group (pos. 7) or the right group (pos. 8) is turned on, with the help of which the first or second light streams are formed.

The disadvantages of the known IGmk include: the great complexity of manufacturing BOIG, the impossibility of using the redundancy of optical light emitters, which is embedded in the design of light blocks in the event of a failure of one of the groups of optical light emitters, the difficulty of performing the operation of fixing the BOIG under operating conditions, and the distortion of the direction of the rays of the second light flux in space with the adopted scheme for installing wedges on the circuit boards of light blocks.

The objective of the invention is to eliminate the disadvantages of the above indicator.

The technical and economic effect of the IGmk utility model is to increase operational characteristics and reduce the complexity of its manufacture.

The technical result of the proposed solution is to increase the reliability of IGmk by introducing into its composition two identical BOIGs, each of which includes light units, with which it is possible to form one light stream. The luminous flux of one of the BOIG is directed to the front panel of the IGMK, and the second - at an angle to it in accordance with the given course of the helicopter landing, the introduction of a remotely controlled mechanism for fixing the pendulum in its original position.

The design of IGMK is similar to the prototype scheme and is explained in the sketches. Its main elements are the indicator housing (pos. 1), the pendulum (pos. 2), the gimbal (pos. 3).

The pendulum consists of a suspended mounting frame of the pendulum (pos. 2.1), made in the form of a closed frame with two horizontally mounted shelves: upper (pos. 2.2vp) and lower (pos. 2.2np). On the shelves at an angle β to the horizon, the upper (pos. 2.2c) is installed with the help of the upper installation wedge (pos. 2.2.11 c) and the lower (pos. 2.2n) with the lower installation wedge (pos. 2.2.11n) ( Pos. 2.2c, 2.2n). In this case, one of them, for example (2.2n), is installed with the front panel parallel to the front plane of the IGmk housing, and the second (pos. 2.2c) - at an angle ϕ to the first in the horizontal plane.

BOIG is a prefabricated structure consisting of a welded body (pos. 2.2.1 in Fig. 5) and a base (pos. 2.2.8). LED blocks (pos. 2.2.2, 2.2.3 and 2.2.4) are installed in the welded case (pos. 2.2.1) based on the AIS in an amount sufficient to form one three-beam light flux, and not two (pos. 7 and 8 in Fig. 1), as in the prototype.

The central light unit (pos. 2.2.3 of Fig. 3) is installed in the FACE with the front panel parallel to its front plane. Adjustment (adjustment) of the position of the LED blocks (pos. 2.2.2 and 2.2.4 of Fig. 3), located above and below the central block (pos. 2.2.3), relative to the block (pos. 2.2.3) is performed by the BOIG when assembling the product , which subsequently significantly reduces the complexity of manufacturing and debugging of IGMk as a whole.

In the proposed IGmk, the fasteners are located on the lower power panel, which allows you to install the IGmk on the foundation, and not under it, as in the prototype. If necessary, shock absorbers can be installed on the IGmk housing for its vibration protection in operating conditions. At the same time, shock absorbers are installed under the lower power panel and on the rear wall of the housing at the top.

IGMK works as follows.

Power supply is supplied to the IGMK and, depending on the heading angle of the helicopter, the upper (pos. 2.2c, Fig. 4) or lower (pos. 2.2n of Fig. 4) BOIGs are switched on. When approaching, the pilot is guided by the lights that he perceives while in the range of the indicator light rays shown in FIG. 3.

In case of failure of one of the BOIGs, the approach approach may be provided with the help of another BOIG.

Upon termination of operation, the IGMC is brought to its initial position by issuing a command to the remotely controlled mechanism for fixing the pendulum to its original position (pos. 6 of Fig. 4) and turning off the power.

The advantage of the utility model is to increase the reliability of the IGmk by introducing two identical BOIGs, reduce the complexity of manufacturing and debugging (adjusting) the BOGG, significantly reduce the service time of the IGmk by using the remotely controlled locking mechanism of the IGmk pendulum, and increase the service life of the IGmk pendulum in operating conditions due to use of the mechanism of its fixation.

The technical and economic effect of the utility model is to increase the technical and operational characteristics of the product.
