Description
Technical field:
The utility model belongs to the air equipment technical field, particularly a kind of aircraft with falling protecting device.
Background technology:
As everyone knows, situation when aircraft accident occurs in the high-altitude is very fearful, at present, and in the middle of the existing flight of aircraft, emergency episode is handled and can't be solved, all the time exist an insurmountable defective in-flight failure problem, aircraft in the past, especially aircarrier aircraft, in case aircraft belly alighting gear hardover failure takes place, the just unavoidable difficulty that is all in vain, the fatal crass, the loss that causes to the country and people also is huge.The annual all over the world generation that all has the aircraft high-altitude to survive an accident is suffered heavy losses, and various countries also pay much attention to this.Busy along with air communication, and natural environment is abominable day by day, the air crash accident happens occasionally.Avoid taking place the airplane crash incident, the safety of protection aircraft and the security of the lives and property on the machine still are a global problem at present.
The utility model content:
The purpose of this utility model provides a kind of aircraft with falling protecting device of practical, safe, good reliability.
For achieving the above object, the utility model adopts following technical scheme:
A kind of aircraft with falling protecting device; comprise fuselage, wing and afterbody, the belly on fuselage is provided with interlayer to be opened/closed, is provided with air-cushion device and high pressure air delivery device in the interlayer; air-cushion device is communicated with the high pressure air delivery device, and body upper is provided with the directed wing.
The described directed wing is dovetail form, dull and stereotyped square or dull and stereotyped circle.
Described air-cushion device inflation back is the cuboid air cushion.
Described air-cushion device is the formation buffer zone that caves inward.
Described high pressure air delivery device has gas piping, and gas piping is communicated with air-cushion device.
The utility model beneficial effect is: owing on the aircraft air-cushion device is installed; this air-cushion device is communicated with airflow line; body upper is provided with the directed wing; fixing falling direction makes aircraft run into catastrophic discontinuityfailure when flight, but when being difficult to get rid of; in emergency circumstances; start air-cushion device,, retrieve tremendous loss to the country and people no matter all can protect the safety of aircraft in the ground landing or in drop in water surface.

The specific embodiment:
In order better to understand the utility model, be further described below in conjunction with accompanying drawing.
See accompanying drawing 1～8; a kind of aircraft with falling protecting device; comprise fuselage 1; wing 2 and afterbody 3; belly on fuselage 1 is provided with interlayer 11 to be opened/closed; be provided with air-cushion device 4 and high pressure air delivery device 5 in the interlayer 11; this air-cushion device 4 is communicated with high pressure air delivery device 5; fuselage 1 top is provided with the directed wing 8; the described directed wing 8 is a dovetail form; dull and stereotyped square or dull and stereotyped circle; described air-cushion device 4 inflation backs are the cuboid air cushion; described air-cushion device 4 forms buffer zone 7 for caving inward, and described high pressure air delivery device 5 has gas piping 6, and gas piping 6 is communicated with air-cushion device 4.
See accompanying drawing 1～3 and accompanying drawing 7～8, the belly on fuselage 1 is provided with interlayer 11 to be opened/closed, is provided with air-cushion device 4 and high pressure air delivery device 5 in the interlayer 11, and this air-cushion device 4 is communicated with high pressure air delivery device 5 by gas piping 6.Fuselage 1 top is provided with the directed wing 8, and the directed wing 8 is a dovetail form.When dangerous situation appearred in aircraft, because the heavy and light of the directed wing 8 of dovetail form and fuselage 1 is poor, the aircraft falling direction is fixing all the time, and the directed wing 8 of dovetail form all the time up; Then chaufeur is opened belly open and close type interlayer 11 in the operator's compartment inner control, rapidly air-cushion device 4 is inflated by gas piping 6 by high pressure air delivery device 5, air-cushion device 4 is exposed at outside the interlayer 11 fully, and putting on the air reaches the preset air pressure requirement, and it is the cuboid air cushion that air-cushion device 4 forms an outer ring.Air-cushion device 4 has certain area in the aircraft dropping process, air-cushion device 4 forms buffer zone 7 for the mediad sunken inside, 7 pairs of original air-flows of buffer zone produce resistance, make the air-flow formation eddy current that changes, the pressure that also can make upper surface is less than lower surface pressure, produce pressure difference, this aerodynamic force is called suction upwards enhanced feature.No matter aircraft falls earthward or the water surface all plays the picking-up effect, reduce impulsive force, guarantee safely dropping.Land earthward as aircraft, when contacting with ground, the buffer zone 7 of air-cushion device 4 can play secondary and slow down the impulsive force function, the outer ring is formed centrally a hollow buffer zone 7 in exceeding for the first time, the air of the inside becomes holder power with the pressure contravariant that air-cushion device 4 is subjected to the aircraft deadweight, and the impulsive force that reduces a part produces a pooling feature; Buffering is to be provided with the air-cushion device 4 that is lower than the outer ring at belly for the second time, the stressed excessive belly device that is retracted to a certain degree carries out secondary buffer and plays and hold up and reduce the effect of impact dynamics when the outer ring, prevent that fuselage is explosion caused because of impulsive force excessive impact ground, reach the effect that safety is landed.If aircraft is identical with the ground all functions to drop in water surface, but air-cushion device 4 can produce certain displacement, and aircraft can swim in the water surface as the naval vessel, reaches the safe life-saving effect.
See accompanying drawing 4～8, this is the utility model embodiment 2, the place different with embodiment 1 be the directed wing 8 of embodiment 2 for dull and stereotyped square, other structures are identical with the structure of embodiment 1, principle of work is identical with embodiment 1, here no longer repetition.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
