Problems solved by technology

[0003] In order to overcome the shortage that the existing helicopter personnel protection technology cannot provide sufficient protection for personnel in the case of a high-height and high-speed crash, and at the same time cannot ensure the safety of equipment when the height is not high and the crash speed is not high. The invention provides a new type of active airbag for helicopters, which can not only ensure the safety of personnel, but also ensure the safety of equipment when the height is not high and the falling speed is not high

Abstract

An active high-safety air bag for helicopter features that several air bags and several gas generators communicated to said air bags (one to one) via inflating tube are arranged in the recesses on the bottom of helicopter body and a controller close to the driver' s seat is used to control said gas generators.

Description

Technical field [0001] The invention relates to an air bag device, in particular to an air bag device capable of providing protection for a helicopter. Background technique [0002] At present, the personnel protection technology of helicopters adopts the design of energy-absorbing body and reinforces the cockpit. When the helicopter loses control and crashes, the body is deformed due to the collision and absorbs part of the energy. At the same time, the reinforced cockpit reduces the probability of cockpit deformation. It also reduces the probability of injury to the crew due to the deformation of the cockpit. But there is an irreconcilable contradiction in this approach. In order to ensure the safety of the people on board, when the helicopter crashes, the acceleration experienced by the people cannot exceed a certain value, usually 15 to 20 g. When a crash occurs at a certain height, the greater the deformation of the body, the greater the buffer distance provided. The ...
