On be fixed with blade.Circular configuration symmetry is good, and all blade orders in circular configuration tilt, so that positioned at always
The incline direction contrast of two blades on footpath, caused horizontal thrust are cancelled out each other, and only produce upward lift, according to
The difference of the blade anglec of rotation forms different lift, ensures the difference of unmanned plane required lift in varied situations.
Preferably, described change lift structure includes concentric outer ring and inner ring, it is evenly equipped between outer ring and inner ring
Blade rotary shaft, blade are fixed in blade rotary shaft, and the radial arrangement in outer ring has fixed pole, are become lift structure and are passed through admittedly
Determine pole with horn to be connected.Rotary shaft and blade, while the centrally convenient arrangement spiral of inner circle are conveniently arranged by inner ring and outer ring
Oar and fuel engines, improve space availability ratio.Fixed pole improves the stability of structure, at the same will conveniently become lift structure with
Horn is connected.
Preferably, described change lift structure is located at below propeller, the spindle central of propeller is with becoming lift structure
Center superposition.Fuel engines and propeller are respectively positioned on the top for becoming lift structure, prevent from hindering to be used for fuel engines
The air-flow of radiating, lower deflection air-flow caused by blade is facilitated to cool down fuel engines.
Preferably, the described blade anglec of rotation is 0 ° -90 °.It is big with the different adjustment lift of blade flip angle
Small, when blade is arranged vertically, lift is maximum.
Preferably, described horn is distributed on fuselage, undercarriage is provided with below fuselage.Protect the fuselage peace of unmanned plane
It is complete to land.
Rotated preferably, described propeller is driven by fuel engines.Cruising time is grown, and possesses higher load.
Therefore, a kind of multi-rotor unmanned aerial vehicle for becoming lift structure of the present utility model possesses following advantages：
（1）The utility model becomes lift structure fast high efficient oil and moves multi-rotor unmanned aerial vehicle, there is lift to regulate and control fast excellent
Gesture, realize the characteristics of dynamic posture action regulation of oil is rapid.
（2）The fuel engines that the utility model becomes the dynamic multi-rotor unmanned aerial vehicle of the fast high efficient oil of lift structure does not adjust fuel oil
Engine speed, reliability are high.
（3）The utility model fuel engines is in economic speed point, and rotating speed keeps constant, and reliability is high, long lifespan, no
It is easily flame-out.

Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical scheme of utility model is described in further detail.
Embodiment：
As illustrated in fig. 1 and 2, a kind of multi-rotor unmanned aerial vehicle for becoming lift structure, including fuselage 10, consolidate in the lower section of fuselage 10
Surely there is undercarriage 11, undercarriage protects the security of whole fuselage to land when unmanned plane lands.4 horns are connected with fuselage
9, horn 9 is uniform to be connected on fuselage 10.Horn 9 is for supporting fuel engines 2 and propeller 1 thereon.In horn
Upper be fixed with simultaneously becomes lift structure 3.Become lift structure 3 as symmetrical circular configuration, propeller 1 is in change lift structure
The heart, and propeller 1 and fuel engines 2 are respectively positioned on the top for becoming lift structure 3.Fuel oil is connected with the lower section of propeller 1
Engine 2, fuel engines 2 drives propeller 1 to be run with a constant rotating speed, and the lift provided is becoming lift structure 3
Regulation under quickly form the lift of different working condition demand.
Becoming inner ring 5 and outer ring 8, radially connected in outer ring 8 of the lift structure including arranged concentric has two fixed poles
4, two fixed poles 4 are arranged in right-angled intersection.Become lift structure to be fixed on horn 9 by fixed pole 4.In the He of inner ring 5
Blade rotary shaft 6 is evenly equipped between outer ring 8, the both ends of blade rotary shaft 6 are plugged on inner ring 5 and outer ring 8 respectively, blade rotation
Axle 6 can be rotated according to the instruction of control system.Blade 7 is fixed with blade rotary shaft 6, blade 7 rotates in blade
Rotated under the drive of axle 6, the gap formed between adjacent blades, air-flow produces thrust by gap, and thrust can decompose
For level thrust and upward lift, because the direction of rotation of blade rotary shaft is identical, thus positioned at it is same diametrically two
The incline direction contrast of individual blade, so, horizontal thrust caused by two blades are cancelled out each other, and only remain upward liter
Power, adjusted by adjusting blade between 0 ° -90 °, so that it may required any lift is obtained, to adapt to the demand of state of flight
Amount.The algorithm of original control system need not be changed, just can be in the case where fuel engines power output be consistent, to adjust
The flight lift of unmanned plane.
