Description

A kind of aircraft

Technical field

A kind of aircraft, belongs to airborne vehicle, specially VTOL aircraft.

Background technology

At present, there is the aircraft of the wing, by the lift of the wing, cruising speed is fast and oil consumption is few, but landing is difficult, because of the first exhausted condition of necessarily organic field runway, limit the application of wing aircraft；And the propeller helicopter without wing, although the puzzlement without airfield runway problem, because oil consumption is big, medium of speed meets rescue, exploration, use in the smaller range traveled, so the two advantage can not be taken into account, use scope of the aircraft in communications and transportation is limited.

At present, the osprey transporter in the U.S., by engine at wing tip, its external form exactly likes osprey and gained the name.Although just energy VTOL, without runway, has the design of the wing and with the advantage in speed to osprey machine rotary Engine.But its defect limits the performance of its advantage：1st, such as engine is arranged at wing tip, although its engine-thrust is not affected substantially, but the carrying of fuselage is moved to the both sides of wing by center, and the bearing capacity of wing wants the reinforcement of decades of times, adds cost and the heavy burden of aircraft.2nd, power source is too remote from center, in addition to its aircraft turns to express effect, can make balance degree-of-difficulty factor increase when takeoff and landing, hovering, flight, facilitating osprey machine turns into the aircraft most easily having an accident in the world.Its reason is, the power source of other aircraft is all at fuselage, as passenger plane body of disembarking is also close, such as one is cut the engine, also return ground only can be support by the engine of half power, even the aircraft of an engine stops working, also there is forced landing successful by the lift gliding of wing, cut the engine as long as having osprey machine only and being one, another engine, which will do aircraft quickly to rotate, causes out of control, make osprey machine have the machine of falling specific term (other aircraft meet accident only cries air crash, collide), the advantage of peace and two engines are kept tie, fearful unsurmountable inferior position is changed into by osprey machine.

The content of the invention

Overcome the shortcomings of osprey machine, engine is set by more remote better from aircraft center, it is more near better to be inverted as, and its engine is fixed by a bit, is changed at 2 points and is entrusted：Rotational support point can be set in engine front portion, rear portion is the moving point that oil cylinder stretches；Also can be rotational support point, the moving point that front portion is stretched for oil cylinder by engine rear portion.

Engine lean on centrally disposed two brought big benefits：1st, lean against fuselage, can with easy mounting bracket can stationary engine, its cost is few and lightweight, can mitigate airplane load, what is retrieved is speed advantage and fuel-economizing advantage.2nd, the worm gear of non-blade, snail fan air compress the engine aircraft of class, engine front portion can use to set rotational support point, rear portion is 2 fixing means of the moving point that oil cylinder stretches, and the installation place of engine is still transformed in former wing end, with regard to that can make to have wing aircraft to add VTOL function.

Set first aid umbrella and parachute mechanism on wing, the problem of engine of aircraft always has flame-out, cut the engine simply just in case, can be just in case be exactly disaster.But two engines are simultaneously faulty flame-out, can be just in case in contingency, so only need to tackle be an engine failure when first-aid method.When such as an engine is abnormal flame-out, another engine will be adjusted to landing state, and aircraft at most tilts twenty or thirty degree, also can not damaged landing.As opened first aid umbrella at wing tip, so that it may promote aircraft balanced slowly to land, the technology is reached the safer hardware more than currently all aircraft.

The present invention uses following technical scheme：

A kind of aircraft, is made up of fuselage, wing, engine, engine combined bay etc., and described engine combined bay is made up of carrier, engine support, oil cylinder, it is characterised in that：Frame stretches out from fuselage, can independent weight bearing also with inboard it is L-shaped make a concerted effort, engine support is set on frame, engine support is vertically arranged with fuselage, in engine support, set afterwards and the ring on engine root or hole attachment pegs, before set multistage ram machine machine, pass through oil cylinder telescopic action, engine can be made to hold up or put down 2 points of support engine structures of the flat lifting type plowed, worm-gear type, the snail fan non-blade engine of formula, can rotate on engine front portion and the wing side strong point at fuselage, with the moving point of the rear portion of engine as oil cylinder under the wing, oil cylinder can make engine vertical operation under release effect, aircraft is in take off or landing state, oil cylinder can make engine horizontal when packing up, aircraft is set to be in 2 points of support engine-models of cruising speed.

A kind of aircraft, is made up of, described wing fuselage, wing, engine, engine combined bay etc., it is characterised in that：Automatically the first aid umbrella opened is set inside, when an engine is flame-out because of chance failure, open the first aid umbrella control door on wing, first aid umbrella can be from wing Inner automatic springs, its first aid umbrella handle also needs to be provided with elastic device, moment drag when available buffer opens, first aid umbrella may be alternatively provided as the combining form that umbellule drags gamp.

A kind of aircraft, is made up of, described combined bay fuselage, wing, engine, engine combined bay etc., by fuselage cradle and engine fixing axle, turns mechanism and constitutes, it is characterised in that：It is stretched out from fuselage, and end covers for circle, and the axle of stationary engine is set in set, and axle adjusts working condition by turning mechanism controls, rotatable engine.
