Embodiment Construction

[0043] The buoy cabin of the integrated helicopter emergency floating system provided by the present invention will be explained below in conjunction with the accompanying drawings.

[0044] Such as Figure 1-6 As shown, the present invention proposes a buoy cabin of an integrated helicopter emergency floating system, which is mainly composed of a buoy cabin partition 1, an inflatable bottle 2, a buoyant bag 3, a mooring belt 6, a fixed bracket 7, a protective piece 8, and a peripheral waterproof seal 9, soft cover 10, rubber patch 11, foam pad 12, hinge 13, locking wire 14, screw 15, washer 16, connecting belt 17 and so on.

[0045] The buoy compartment partition 1, as the main body of the buoy compartment, is embedded in the inside of the helicopter fuselage, including a first plane and a second plane. The two planes form a preset angle, and the angle faces the outside of the helicopter fuselage. The buoyant bag 3 is placed in the angled area; the soft cover 10 covers the b...

Abstract

The invention provides an integrated helicopter emergency floating system buoy cabin. The integrated helicopter emergency floating system buoy cabin comprises a buoy cabin partition plate (1), an inflation bottle (2), a floating bag (3), a soft cover (10) and a hinge (13). The buoy cabin partition plate (1) is arranged in a helicopter body and comprises a first plane and a second plane, the two planes form a preset included angle, the included angle faces the outside of the helicopter body, and the folded floating bag (3) is placed in the included angle; the soft cover (10) covers the floating bag (3) and keeps consistent with the aerodynamic shape of the helicopter body; the first plane is horizontally arranged, a semicircular concave part is arranged on the first plane, the inflation bottle (2) is embedded in the concave part, the top end of the second plane is connected with the first plane, and the bottom end of the second plane is rotationally connected to the interior of a helicopter body through the hinge (13). An inflation pipeline is short, light in weight and high in reliability.

Description

technical field [0001] The invention belongs to the field of helicopter buoy cabin design, in particular to an integrated helicopter emergency floating system buoy cabin. Background technique [0002] The helicopter emergency flotation system can provide a stable buoyancy for a certain period of time for the helicopter that is forced to land on the water surface, which is convenient for the personnel on board to evacuate from the helicopter to the life raft safely, and provides safety guarantee for the helicopter's water operation. [0003] The emergency flotation system usually includes a control system and an inflation system, wherein the inflation system usually includes an inflatable bottle and a buoyancy bag. In the existing helicopter emergency flotation system design, a configuration in which the buoyant bag and the inflatable bottle are arranged separately is usually adopted, that is, the buoyant bag is arranged in the external buoy cabin, and the inflatable bottle i...
