A., on the carbon plate shelf of location, the lower end is separately installed with power motor, two power motors are gone up rotor and following rotor by corresponding respectively connection of gear, the rotating shaft coaxle of last rotor and following rotor is fixed on the center of location carbon plate shelf, the left side of location carbon plate shelf, the right side connects two steering wheel servomechanisms respectively, the steering wheel servomechanism connects aspect control rudder by the steering wheel rocking bar, the side of one aspect control rudder is connected with rotor upset servomechanism, and the afterbody that central authorities have the rotor duct is provided with the propelling propeller.

Technique effect of the present utility model is: 1, adopt a coaxial reverse rotor that is opposite to fuselage central authorities, can effectively overcome traditional about two tilting rotors cause the uneven and problem of the aircraft rollover that produces of lift easily; 2, before rotor verts, adopt the thrust that advances propeller to carry out preacceleration and in the process of verting, keep necessity, guarantee the stability of aircraft flight MODAL TRANSFORMATION OF A when rotor verts; 3, the flexible combination that can be by four aspects control rudders and the adjusting of gyroplane rotate speed are controlled aircraft very easily and are being hovered and attitude during state of flight.

Description of drawings

Fig. 1 has the structural representation of the fuselage of rotor duct for the utility model central authorities.

Fig. 2 is a structural representation of the present utility model.

In the drawings, 1, central authorities have the rotor duct fuselage 2, rotor S. A. 3, location carbon plate shelf 4, power motor 5, go up rotor 6, down rotor 7, steering wheel servomechanism 8, steering wheel rocking bar 9, aspect control rudder 10, rotor upset servomechanism 11, advance propeller

The specific embodiment

As Fig. 1, shown in Figure 2, the utility model is achieved like this, central authorities have on the duct of fuselage 1 of rotor duct and are connected with rotor S. A. 2, the intracardiac location carbon plate shelf 3 that is provided with in the rotor S. A. 2, on the carbon plate shelf 3 of location, the lower end is separately installed with power motor 4, two power motors 4 are gone up rotor 5 and following rotor 6 by corresponding respectively connection of gear, the rotating shaft coaxle of last rotor 5 and following rotor 6 is fixed on the center of location carbon plate shelf 3, the left side of location carbon plate shelf 3, the right side connects two steering wheel servomechanisms 7 respectively, steering wheel servomechanism 7 connects aspect control rudder 9 by steering wheel rocking bar 8, the side of one aspect control rudder 9 is connected with rotor upset servomechanism 10, and fuselage 1 afterbody that central authorities have the rotor duct is provided with propelling propeller 11.

Now sketch the specific embodiment of the present invention in conjunction with the typical flight course of aircraft " take off vertically------flying the fast---vertical landing of hovering ".

(1) take off vertically: this moment, rotorshaft was in vertical state, two rotor constant speed counter-rotatings, and afterbody advances propeller not work, and rotor rotates the lift that produces vertically upward, aircraft vertical uplift.

(2) hover: when VUAV take off reach predetermined altitude after, thereby make lift equate to be in floating state with aircraft gravity by the control gyroplane rotate speed, for the stability that guarantees the hang state is being equipped with attitude coutrol mechanism in the middle of the rotor up and down---attitude control rudder, as shown in Figure 2.Above attitude control rudder, current plate is arranged, when about four control rudders rotate forward synchronously or the certain angle that rotates backward after, the effect that is subjected to the downward air-flow that rotor produces can realize pitch control subsystem.After turning an angle respectively before and after two control rudders of a side, can block a side direction downstream and change this side lift size, realize rolling control.When left and right sides control rudder rotates simultaneously in the opposite direction, can make the yaw angle about aircraft produces.Also can pass through above the change or the rotating speed of following rotor, make aircraft produce the driftage moment of torsion, the original place rotates, the control of realization course.

(3) fly before fast: the afterbody propeller is started working when VUAV will fly state before floating state forwards to, promoting aircraft flies forward, when reaching certain forward flight speed, wing produces certain lift, overturn forward when rotor and attitude coutrol mechanism can be opened under the drive of upset control motor this moment, the lift of loss when wing produces lift and compensates rotor and vert when being flown forward by aircraft.Rotor all is used for producing aircraft thrust forward when rotorshaft forwards level attitude to, and aircraft flies before beginning fast.Because VUAV adopted the tail-rotor propelling, so aircraft has possessed certain forward flight speed when rotor overturn, promptly wing has produced a part of lift, so the process that flies before the full speed of hovering is more stable, and manipulation easily.

Rotor inclines when turning 90 degrees, and the control rudder also rotates 90 degree with axle.When about after four control rudders upwards rotate synchronously or rotate certain angle, the effect of the air-flow that is subjected to flying can realize pitch control subsystem.After two control rudders of a side turn an angle respectively up and down, can realize course control.When left and right sides control rudder rotates simultaneously in the opposite direction, can realize the control of rolling.

(4) vertical landing: this moment rotor in the control turning down of upset motor, produce lift upwards, the loss that the airfoil lift that the speed that remedied reduces to bring reduces.The afterbody propeller stops the rotation after rotorshaft goes back to vertical state, and the aircraft forward flight speed reduces gradually, and the lift of aircraft changed by rotor and produced this moment.The revolution that reduces rotor can reduce the lift aircraft and begin vertical decline, realizes vertical landing.
