Description

A mounting bracket for a helicopter horn

technical field

The invention belongs to the technical field of helicopter structural parts, in particular to a mounting bracket for a helicopter horn.

Background technique

Due to the needs of performing various tasks, helicopters are often equipped with an air broadcast system for the helicopter pilot or crew members to shout to the ground. However, due to the limitation of the installation position and space of the helicopter body, the loudspeaker in the air broadcasting system has been installed on the outer skin under the floor of the luggage compartment. This installation position is also the installation position of the air conditioning system and Doppler radar, resulting in three options. The dilemma that mission equipment cannot be installed at the same time.

Contents of the invention

The technical problem to be solved in the present invention:

By designing a mounting bracket for the helicopter horn, the horn is installed on the outer skin of the right side of the helicopter fuselage to solve the problem of interference between the horn and the air conditioning system and Doppler radar system, while considering the characteristics of the horn use, installation, disassembly and maintenance . Technical scheme of the present invention:

A mounting bracket for a helicopter horn, comprising a bracket rear web 5, a bracket lower web 6, a bracket front web 7, the bracket rear web 5 and the bracket lower web 6 are riveted by rivets, the bracket lower web 6 and the bracket front web 7 Through rivet riveting, there are bracket installation holes 3 on the rear web 5 of the bracket and the front web 7 of the bracket, which are used to fix the horn 1, and the rear web 5 of the bracket and the front web 7 of the bracket pass through the bracket assembly holes on the ribs 4. Use screws to connect to the skin of the fuselage. Inserts are preset in the skin of the fuselage, and each part is designed with rigidity.

Rubber gaskets are installed at the bracket mounting hole 3 and the bracket mounting hole 4.

Beneficial effects of the present invention:

Through the newly designed bracket, the horn is installed on the outer skin on the right side of the tail section of the helicopter, which solves the problem of interference between equipment, and at the same time solves the installation and use of the air broadcast system, and considers the quick disassembly and replacement of the horn.

detailed description

A mounting bracket for a helicopter horn, comprising a rear web 5 of the bracket, a lower web 6 of the bracket, and a front web 7 of the bracket.

The rear web 5 of the bracket and the lower web 6 of the bracket are riveted by rivets, the lower web 6 of the bracket and the front web 7 of the bracket are riveted by rivets, and there are bracket installation holes 3 on the rear web 5 of the bracket and the front web 7 of the bracket, which are used to fix the horn 1.

The rear web 5 of the bracket and the front web 7 of the bracket are screwed to the fuselage skin through the bracket assembly hole 4 on the rib. Inserts are preset in the fuselage skin, and each part adopts rigidity design.

In order to increase the shock resistance, facilitate assembly and prevent abrasion to the skin of the fuselage, rubber gaskets are installed at the bolt joints.
