A kind of vertical take-off and landing drone
Technical field
The present invention relates to a kind of unmanned planes, are related specifically to a kind of vertical take-off and landing drone.
Background technology
Since unmanned plane has the advantages such as small, at low cost, and with flight control technique, the communication technology and electronic technology
Fast development, the performance of unmanned plane constantly enhances, type is on the increase, and makes its application in military domain and civil field
Demand constantly increases.
Unmanned plane is typically divided into fixed-wing unmanned plane and rotary wings unmanned plane.
Wherein fixed-wing unmanned plane is pushed by engine, and engine driving generates the horizontal thrust for being parallel to fuselage axis, makes
Unmanned plane can high-speed flight in the air.But since engine cannot generate the lift perpendicular to fuselage axis, so fixed-wing
Unmanned plane can only obtain lift by the relative motion between fixed-wing and air, to overcome the gravity of fixed-wing unmanned plane, rise
There are positive correlations for speed of related movement between the size and fixed-wing and air of power, and speed of related movement is bigger, fixed-wing
The lift that unmanned plane is obtained is also bigger.In the prior art, there is two disadvantages for fixed-wing unmanned plane:First, it is needed when taking off
Want longer runway just fixed-wing unmanned plane can be made to obtain enough horizontal velocities, so that fixed-wing unmanned plane obtains enough liters
Power is taken off;Second, fixed-wing unmanned plane need to keep after take off enough flying speeds could obtain enough lift with gram
Take the gravity of itself.
Rotary wings unmanned plane makes rotary wings around own axes rotation by engine, and when rotary wings rotation generates opposite with air
Movement obtains lift.Since the lift that rotary wings unmanned plane generates directly transfers generation, rotation certainly by engine driving rotary wings
Rotor unmanned plane takes off need not have horizontal flight speed, that is, eliminates the reliance on runway, overcome fixed-wing unmanned plane rely on it is longer
The shortcomings that runway.Meanwhile rotary wings unmanned plane also overcomes after fixed-wing unmanned plane takes off and needs to keep enough flying speeds
The shortcomings that, rotary wings unmanned plane can be vertically moved up or down, hovering, left and right is flown forwards, backwards, have flight attitude diversified
Advantage.But due to the mainly lift that rotary wings provide, the level for being parallel to fuselage axis of rotary wings unmanned plane acquisition pushes away
Power is smaller, so horizontal flight speed is slower.
In conclusion in the prior art, or unmanned plane needs to rely on long runway, and needing holding is enough to fly after taking off
Scanning frequency degree;Horizontal flight speed is slower.

With reference to figure 1 and Fig. 2, when taking off, first vertical take-off and landing drone to be placed vertically, fuselage axis is perpendicular to the ground, and four
A vertical fin 4 lands as undercarriage;4 motor rotations are driven under the control of flight control system by lithium battery, and drive 4
Propeller 6 is around own axes rotation.And 4 propellers 6 is made to be divided into two groups according to diagonal line, two groups of propellers 6 rotation
Direction on the contrary, with offset propeller 6 rotation generate anti-paddle power.Propeller 6 is parallel to fuselage around own axes rotation generation
The pulling force of axis, makes vertical take-off and landing drone that gravity be overcome to take off.
With reference to figure 1 and Fig. 3, after vertical take-off and landing drone rises to certain altitude, lithium battery is in flight control system
The lower driving steering engine of control simultaneously drives aileron 8 around the rotary shaft rotation perpendicular to fuselage axis, by adjusting aileron 8 so that vertical
Landing unmanned aerial vehicle body head pulls down, and vertical take-off and landing drone enters flies to horizontal flight transition stage vertically.
With reference to figure 1 and Fig. 4, as vertical take-off and landing drone fuselage head pulls down, the power that propeller 6 generates gradually changes
For horizontal flight power, vertical take-off and landing drone enters the high-speed horizontal flight stage.
When vertical take-off and landing drone needs landing, lithium battery drives steering engine and is driven under the control of flight control system
Aileron 8 around perpendicular to fuselage axis rotary shaft rotation, pass through adjust aileron 8 so that vertical take-off and landing drone fuselage head to
Pull-up, as the unmanned chain-drive section of landing is constantly pulled up, the horizontal flight power that propeller 6 provides is gradually converted into upward drawing
Power, pulling force and the vertical take-off and landing drone its own gravity that final propeller 6 generates on one wire, when the drawing that propeller 6 generates
When power is less than landing unmanned plane its own gravity, vertical take-off and landing drone slowly vertical landing.It can be with continued reference to Fig. 2 when landing.
Although present disclosure is as above, present invention is not limited to this.Any those skilled in the art are not departing from this
It in the spirit and scope of invention, can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
Subject to the range of restriction.
