Background technology
Since 21 century, increasing aircraft development business has invested the fixed wing aircraft of vertical takeoff and landing sight, this kind of aircraft has the function similar to helicopter, do not need by runway just energy vertical and landing takeoff, aloft can be verted by power from floating state unlike, this kind of aircraft and flatly fly to accelerate and be transitioned into the offline mode of fixed-wing.
At present, practical vertical takeoff and landing fixed wing aircraft mainly AV-8 sparrow hawk formula fighter plane, V-22 osprey tilt rotor aircraft, F-35 opportunity of combat.What AV-8 sparrow hawk formula opportunity of combat adopted is flying horse driving engine, and jet engine basis have employed the rotatable thrust vectoring scheme of ejector exhaust pipe, and in actual use, this type aircraft often occurs integrity problem, is also referred to as " widow's aircraft ".V-22 osprey formula tiltrotor is a tiltrotor manufactured by American Bell Incorporated and Boeing's collaborated design, is also a medium transport aircraft.It realizes the conversion of rotor between vertical and horizontal direction by two lifting airscrews of tilting wing two ends wing tip, thus more ideally the feature of helicopter and fixed wing aircraft is combined together.Under vertical takeoff and landing state, two rotor thrust directions, perpendicular to ground, utilize auto-bank unit to keep the attitude stabilization of body longitudinal direction.V-22 osprey had both had the ability of pure helicopter vertical takeoff and landing and hovering, had again the ability of the high speed cruise flight of turboprop, was a kind of dual-use new high-tech product.At present, it is mainly used in military requirement, and can give battleficld command official and more select and greater flexibility.It does not need special airport and runway, easy to maintenance, and viability is strong, is specially adapted to carry out special operations, greatly can improve military personnel and deliver, deploy troops on garrison duty, hostile takedown, the speed of the action such as disaster relief.
But because V-22 osprey have employed two lifting airscrews, under vertical takeoff and landing pattern, rotor needs auto-bank unit to control the stable of attitude of flight vehicle, add the difficulty of control, and blade adopts feathering device, too increases cost; And osprey is under vertical takeoff and landing pattern, the positive top blast of rotor slip-stream, on aerofoil surface, causes very large pressure drag loss, and forces wing to increase structural strength, and then cause Flight Vehicle Structure weight to increase, reduce the performance of aircraft.
Summary of the invention
Based on this, the invention provides that a kind of volume is little, the simple vertical takeoff and landing Fixed Wing AirVehicle of structure.
The concrete technical scheme solved the problems of the technologies described above is as follows:
A kind of vertical takeoff and landing Fixed Wing AirVehicle, comprise fuselage, empennage and the engine installation with inclining rotary mechanism, the described engine installation with inclining rotary mechanism comprises fixedpiston screw propeller, driving engine, machinery space, slip-stream rudder, wing, tilting wing and steering wheel, driving engine is installed in machinery space, fixedpiston screw propeller is connected with the output shaft of driving engine, tilting wing one end is fixedly connected on machinery space, the other end is rotating to be connected on wing, slip-stream rudder is movably connected on tilting wing, slip-stream rudder described in servo driving, the described engine installation with inclining rotary mechanism is symmetricly set in fuselage both sides, and be horizontally disposed with for wing, described fuselage head is provided with through hole, ducted fan is established in through hole, a lift is upwards provided for giving vertical takeoff and landing Fixed Wing AirVehicle.
Wherein, described slip-stream rudderpost connects or is hingedly coupled to the end of tilting wing, and is positioned at the one end away from described fixedpiston screw propeller.
Wherein, also comprise rotating shaft, rotating shaft one end is rotating to be connected on wing, and the other end is fixedly connected on tilting wing.
Wherein, the length of described wing is the 35%-55% of fixedpiston diameter of propeller.
Wherein, described wing comprises host wing and wing flap, and wing flap is movably connected on the side of host wing, and host wing is rotationally connected with on tilting wing.
Wherein, described wing flap is articulated with the side of host wing.
Wherein, the diameter of described ducted fan is the 30%-40% of fuselage maximum width.
Wherein, the quantity of the described engine installation with inclining rotary mechanism is 2.
Wherein, described empennage is T-shaped empennage.
Vertical takeoff and landing Fixed Wing AirVehicle tool of the present invention has the following advantages and beneficial effect:
1, aircraft of the present invention, adopt preposition ducted fan and the engine installation with inclining rotary mechanism, it considerably reduces the size of rotor and vertical takeoff and landing Fixed Wing AirVehicle, eliminate complicated auto-bank unit and feathering device simultaneously, structure is simple, reduce the difficulty of trim and the complexity of flight control system, improve the reliability of system, decrease manufacturing cost; This aircraft has vertical takeoff and landing function, can not take off by runway and land, and can play very large effect, also can be used as the Small General Aircraft towards civil aviaton market in navigation, mapping, patrol, transport, warning.
2, aircraft of the present invention, when the state of aircraft vertical landing, the engine installation with inclining rotary mechanism of fuselage both sides, rotate to the direction of engine axis perpendicular to horizontal surface, fixed pitch screw propeller upwards provides lift, and preposition ducted fan starts, and provides a part of lift, and the luffing of aircraft is changed by the change of ducted fan rotating speed, realize aircraft pitch trim; Vert in process at driving engine, changed the pulling force of both sides screw propeller by the rotating speed controlling fuselage both sides driving engine, to control the motion of aircraft rolling, its rolling movement is stablized; Controlled the motion in vehicle yaw direction by the deflection of slip-stream rudder, and it is stable to make it go off course; When engine rotation to forward flat fly position time, slip-stream rudder can replace aileron, air flow deflector is made by differential, produce the rolling moment of aircraft, control the rolling movement of aircraft, make like this wing can adopt large-area wing flap, in landing process, better anti-proliferative effect is played to aircraft, considerably increase the lift coefficient of aircraft, be conducive to aircraft when taking off and reach flat quickly and fly state.
3, aircraft of the present invention, also adopt T-shaped empennage, Fixed Wing AirVehicle realizing while can keep the floating state of vertical takeoff and landing reposefully, can make the driving engine of aircraft in the process that the state of flying is verted forward, keep aspect to stablize, and aircraft finally can be entered, and fixed-wing is flat flies state.
4, aircraft of the present invention, under vertical takeoff and landing state, because fixedpiston screw propeller produces downward wind all in the scope of tilting wing, downward wind can not be there is again in the position of wing, thus make wing only bear fixedpiston screw propeller generation pulling force upwards, and the resistance produced under need not going to bear wind direction again, significantly reduce the resistance loss that wing produces fixedpiston prop-blast, thus the wind making fixedpiston screw propeller produce all is utilized, improve the output efficiency of fixedpiston propeller power.
