Embodiment：
With reference to embodiment, the present invention is described in further detail.
According to Fig. 1, Fig. 2 and Fig. 4, a kind of VTOL fixed-wing unmanned plane with bending moment propeller, including machine
Body 1, the middle part of fuselage 1 and afterbody are fixed with wing 2 and empennage 3, and the empennage 3 at least three, adjacent two panels respectively
Angle between the empennage 3 is less than 180 degree, and is distributed in the empennage 3 of fuselage both sides and is symmetrical arranged, in the trailing edge of wing 2
It is hinged with aileron 7, the empennage 3 and is hinged with tail vane 8, in flight course, unmanned plane is controlled by adjusting the aileron 7
Rolling, the pitching and driftage of unmanned plane are controlled by the tail vane 8, engine 5, engine 5 are provided with the head of fuselage 1
Output shaft on equipped with two groups of bending moment propellers 6, the pitch angle of the bending moment propeller 6 is adjusted by adjusting pitch control shaft, and
The vectored thrust produced in low-speed stage of the unmanned plane in taking-off and landing using bending moment propeller controls unmanned plane
Pitching and course posture, when the unmanned plane is run, the direction of rotation of bending moment propeller 6 described in two groups is on the contrary, and then pass through difference
The relative rotation speed of fast device regulation propeller 6 controls to be provided with buffering lift on the roll attitude of unmanned plane, the empennage 3,
The buffering lift includes：Connecting rod 10, buffer unit 11 and roller 4, described one end of connecting rod 10 are articulated with the empennage 3,
Its other end is hinged the roller 1, and the middle part of the connecting rod 10 is hinged with the buffer unit 11 being installed in the empennage 3,
Under the limitation of the buffer unit 11, the connecting rod 10 is in the place rotation with surface of empennage 3.
Angle is formed between the central shaft of the connecting rod 10 and fuselage 1 so that connecting rod can in landing for the unmanned plane
Slided with the roller 4, in unmanned plane landing, unmanned plane is perpendicular to ground, and connecting rod is parallel to the central shaft of fuselage
Words, may be not easy to drive roller 4 to slide, conversely there is certain angle of inclination, can easily allow connecting rod 10 to drive roller 4 on ground
Unmanned plane jolts when being slided on face, and then reducing landing.
As shown in figure 3, the roller 4 includes two bull wheels 12, a steamboat is folded between two bull wheels 12
13, two bull wheels 12 and steamboat 13 are coaxially disposed, and the outer rim of the steamboat 13 sets with teeth, in unmanned plane during flying,
Under airflow function, drive steamboat 13 to rotate, and then drive roller 4 to rotate.
Illustrate a kind of VTOL fixed-wing unmanned plane with bending moment propeller of the present invention below in conjunction with the accompanying drawings once
Use process：
When unmanned plane takes off：Start engine 5, engine 5 is rotated, produce powerful downdraught, gradually make nobody
The lift of machine is more than gravity, meanwhile, connecting rod 10 is by the traction of buffer unit 11, under the rolling of roller 4, slowly to empennage 3
Close, until buffer unit 11 is contracted to lowest pull state, engine 5 drives bending moment propeller 6 to rotate, liftoff in unmanned plane
When, the downward air-flow that engine 5 is produced drives roller 4 to rotate, and then causes unmanned plane to have higher stability；
In flight course, bending moment propeller 6 is controlled to produce vectored thrust by engine 5 so that unmanned plane is by vertical
Takeoff condition is changed into parallel state of flight, manipulates the rolling that aileron 7 controls unmanned plane, manipulates bowing for the control unmanned plane of tail vane 8
Face upward and go off course, meanwhile, roller 4 is rotated in the presence of air-flow so that unmanned plane during flying is more stablized；
When landing, unmanned plane is controlled by engine 5, makes its hovering in the air, is gradually reduced the lift of unmanned plane, directly
Lift to unmanned plane is less than gravity, and the roller 4 of unmanned plane is contacted with ground, in the presence of the frictional force that roller 4 is subject to, rolling
Wheel 4 drives pull bar 10 to be moved to the direction away from empennage 3, while in the presence of buffer unit 11 so that the motion of roller 4 is strong
Degree weakens, and then unmanned plane jolts when reducing landing, closes engine, completes whole landing mission.
Finally it should be noted that：The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof, to the greatest extent
The present invention is described in detail with reference to above-described embodiment for pipe, those of ordinary skills in the art should understand that：Still may be used
Modified or equivalent substitution, and repaiied without departing from any of spirit and scope of the invention with the embodiment to the present invention
Change or equivalent substitution, it all should cover among present claims scope.
