Embodiment Construction

[0014] figure 1 , 2 As shown in , 3 and 4, the aircraft with the abnormal emergency landing safety protection device of the present invention includes a fuselage 1, and the back of the fuselage 1 is provided with a parachute 3 that can eject the fuselage when the aircraft falls. The head and bottom of the airbag are provided with an airbag device 2 that can pop out the fuselage when the aircraft falls. The airbag device 2 includes an airbag 21 and a rapid inflation device 22. The rapid inflation device 22 is communicated with the airbag 21 through a pipeline 4. 4 is provided with a one-way valve 5. In this embodiment, the rapid inflation device 22 is a combination of a nitrogen compressed gas generator 23 and a sodium azide solid tablet gas generator 24. The nitrogen compressed gas generator 23 includes a high-pressure gas cylinder 231, and an igniter 232, an impact pin 233, a gas cylinder cap 234 and a powder cartridge 235 are arranged at the mouth of the high-pressure gas c...

Abstract

The invention discloses an airplane with an abnormal emergency landing safety and protection device, comprising a fuselage, and the backside of the fuselage is provided with a parachute which can pop out of the fuselage when the airplane crashes; the head part and the bottom part of the fuselage are provided with airbag devices which can pop out of the fuselage when the airplane crashes; the airbag device comprises an airbag and a rapidly inflating device; the rapidly inflating device is communicated with the airbag through a pipeline; the pipeline is provided with a check valve; the rapidly inflating device is a nitrogen compressed gas generator or a sodium azide solid tablet gas generator or the combination of the nitrogen compressed gas generator and the sodium azide solid tablet gas generator; the invention can not only reduce the impact when the airplane crashes, but also increase the waterborne buoyancy force of the airplane and improve the safety performance.

Description

technical field [0001] The invention belongs to aviation equipment, in particular to an aircraft with an abnormal emergency landing safety protection device. Background technique [0002] When the aircraft is in distress in the air or fails to land normally, the aircraft may crash. If the aircraft falls on land, it may explode and burn due to a hard collision. If it falls at sea, it will sink to the bottom of the sea. Up to now, almost all air crashes around the world have killed people and caused heavy losses. At present, the plane crash is still a big problem. Therefore, setting up abnormal emergency landing safety protection devices on the aircraft to avoid or reduce casualties and property losses caused by air crashes plays a very important role in the safety protection of aircraft and personnel. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an aircraft with an abnormal emergency landing safety protection device which can not on...
