Description
Technical field
The invention belongs to air equipment, especially a kind of aircraft that has abnormal emergency landing safety and protection device.
Background technology
When aircraft aloft got into danger or et out of order can not normally land, aircraft just may crash, and just may will sink to seabed if fall at sea because of colliding the burning of blasting firmly if aircraft falls on land.Up to the present, global airplane crash nearly all is the fatal crass, suffers heavy losses.At present, fall for aircraft and airplane crash takes place remain a hang-up.Therefore, abnormal emergency landing safety and protection device is set aboard, avoids or reduce the personal casualty that airplane crash brings and the loss of property, aircraft and personnel's safety guard-safeguard is all had a very important role.
Summary of the invention
The object of the invention provides a kind of impulsive force not only can alleviate aircraft and fall the time, and can increase aircraft buoyancy on the water, the aircraft that has abnormal emergency landing safety and protection device that safety performance is high.
For achieving the above object, the technical solution used in the present invention is: a kind of aircraft that has abnormal emergency landing safety and protection device comprises fuselage, be provided with the parachute that when aircraft falls, can eject fuselage at the back of fuselage, head and bottom at fuselage are provided with the airbag apparatus that can eject fuselage when aircraft falls, described airbag apparatus comprises air bag and quick air-inflating apparatus, quick air-inflating apparatus is connected with air bag by pipeline, be provided with check valve on pipeline, described quick air-inflating apparatus is the combination of nitrogen compressed gas generator or sodium azide solid tablet gas generator or nitrogen compressed gas generator and sodium azide solid tablet gas generator.
Described nitrogen compressed gas generator comprises high-pressure gas bottle, is provided with firing unit, impulse pin, gas cylinder lid and grain at the high pressure gas bottleneck.
Described sodium azide solid tablet gas generator comprises air collector, is provided with grain in air collector, in grain, be provided with the solid tablet firing unit, outside grain, be provided with the solid medicine chamber, separate by filter screen between described solid coyote hole and the air collector chamber, described grain is provided with the aperture that is communicated with grain and solid coyote hole.
After the present invention adopts said structure; owing to parachute is set at the back of airframe and airbag apparatus is set in the head and the bottom of fuselage; when if aircraft is in danger aloft or et out of order can not normally land; can release a parachute and start airbag apparatus; utilize the buoyancy of parachute deceleration and air bag to slow down; utilize the elastic force buffering of air bag itself simultaneously; avoid aircraft to land on land hard collision takes place and explode; also can utilize the buoyancy of air bag; sink to sea when avoiding aircraft to land at sea, reach protection aircraft and personal security or damage of minimizing aircraft and personnel's injures and deaths.
