Description

The utility model relates to the field of aircraft construction, namely, to the structure of fastening the external suspended equipment of an aircraft, for example, a helicopter.

The known design of a suspended pylon (US patent 8800929, B64D 1/12, published 08/12/2014), the body of which is made of monolithic carbon fibers and contains means of attachment to the aircraft in the upper part and attachment points for the suspension equipment in the lower part, as well as interface connector.

Known system of fastening and release of unmanned aerial vehicles (patent US 7624947, F41F 3/065, published on 11.12.2008), containing a bracket attached to the wing or fuselage of the aircraft with fasteners. The pylon is pivotally attached to the bracket through a lever and a transverse hinge pin with the ability to move in the longitudinal direction, as well as rotate.

Known design of the suspension element, which is the closest analogue (patent US 4412475, F41F 3/055, published 01.11.1983), the solid body of which is equipped with attachment points to the pylon of the aircraft, and which remains on the aircraft after dropping the unit suspended from it. At the same time, the high-tech electronic mechanism inside the case is preserved with the possibility of its further use when replacing the suspended unit.

The technical problem solved by the claimed utility model consists in the creation of an adapter device for attaching to a girder holder of a helicopter, which makes it possible to adapt a new external suspended equipment having a certain arrangement of attachment points and electrical connectors, different from the standard arrangement, which is implemented in the design of fastening elements and standard electrical connectors of the on-board network helicopter.

The technical result consists in the possibility of attaching and connecting to the on-board electrical network of new suspended equipment without modifying the standard design of the attachment elements and the helicopter on-board network; increased reliability in flight applications.

The technical result is achieved due to the fact that in the device for attaching to the girder holder of the aircraft, containing a body with fastening elements, in accordance with the claimed utility model, the body consists of an upper and lower beams provided with stiffeners and fixed to each other by means of fastening elements and pins, while inside the body there are electrical harnesses with connectors, while the body is equipped with a box and a fairing.

In addition, on the upper beam there are fastening elements in the form of a front stop, a rear stop, and eye bolts.

In this case, the lower beam is provided with lugs and contains front and rear stops.

Additionally, the harnesses are fixed to the beam walls by means of clamps.

In addition, the box is equipped with lids.

In this case, the fairing is removable.

The presence of a body consisting of upper and lower beams, equipped with stiffeners and fixed to each other by means of fastening elements and pins, equipped with electrical harnesses with connectors, a closed box and a fairing located inside, is designed to connect external equipment to the standard on-board electrical network of the helicopter without special modification last.

The design of the attachment device to the girder holder of the aircraft is illustrated by drawings:

fig. 1 - device for fastening to a beam holder, general view;

fig. 2 - fastening device, side view, section;

fig. 3 - fastening device, top view, section;

fig. 4 - bottom beam, inside view;

fig. 5 - top beam, inside view.

The attachment device to the girder holder is an intermediate element necessary for reliable and safe attachment of the external suspended equipment 18 to the girder holder 30 of an aircraft, for example a helicopter.

The device for attaching to the beam holder of the aircraft contains a housing consisting of an upper 1 and a lower 2 beams (Figs. 1-5). The upper beam 1 and the lower beam 2 are fixed to each other by means of screws 21 (Fig. 1). Pins 3 (Fig. 1, 3), installed in the flanges of the upper and lower beams, serve to relieve the longitudinal load. Also, to ensure resistance to longitudinal and lateral loads arising in flight, in the structure of the beams 1, 2 stiffeners 4 are provided on the inner side of the body (Fig. 4, 5).

Inside the lower and upper beams 1, 2 there are electrical harnesses 5 with connectors 9, 10, 11 for connection to the sockets of the on-board network of the aircraft, and on the other hand, through electrical connectors 22, 23, 24 to the mating parts of the suspended equipment 18 (Fig. 2, 3). For fastening the harnesses 5 to the walls of the beams 1, 2, clamps 6 are provided (Figs. 2, 3).

Box 12 is designed to accommodate, protect electrical connectors 9, 10, 11, access to which is provided by the presence of covers 13, 14 (Fig. 1, 3). Removable fairing 19 covers connectors 22, 23, from environmental influences (Fig. 1, 3).

On the upper beam there are fastening elements to the beam holder 30 in the form of a front stop 7, a back stop 8, eye bolts 6.

On the lower beam 2, equipped with lugs 17, front 15 and rear 16 stops are fixed.

The attachment device to the aircraft girder is applied as follows:

The lower beam 2 is installed on the suspension device 18 by means of the front stop 15, the rear stop 16, the lugs 17 (Figs. 1, 2). The lower beam 2 and the suspension device 18 are fixed to each other by connecting the screws 25 through the lugs 17 (Figs. 1, 2). After the connection, the screws 25 are counter-secured and provide a permanent connection. Then the harnesses 5 are mounted on the walls of the beams 1, 2 and secured with clamps 6 (Fig. 2, 3).

Connectors 22, 23, 24 mate with the connectors of the counterpart of the suspended equipment 18 (Fig. 2). To protect against environmental influences, a removable fairing 19 is installed (Fig. 1, 2).

On the upper beam 1, a front stop 7, a back stop 8, eyebolts 6, a box 12, supports 20 are installed (Fig. 1).

The upper beam 1 and the lower beam 2 are fixed to each other by means of screws 21 (Fig. 1). Electrical connectors 9, 10, 11 are fixed on the upper beam 1 (Fig. 1, 2, 3).

The design of the device for attaching to the beam holder allows you to place the suspended equipment with the required inclination, because the shape of the upper beam 1 is made at an angle, which is selected in accordance with the configuration of the beam holder 30. In this case, the electrical connectors 9, 10, 11 on one side of the housing and connectors 22, 23 on the other side are arranged in such a way that the device acts as an adapter for connection external equipment to the standard on-board electrical network of the helicopter without special modification of the latter.

The assembled body of the device is a reliable means of protecting internal electrical harnesses in flight as well as electrical connectors.
