Abstract

A vertical takeoff and landing aerial vehicle, which comprises a plurality of lift propellers respectively arranged at the top sides of a left linear support and a right linear support, and a left additional lift propeller and a right additional lift propeller respectively arranged on the bottom sides of the left linear support and the right linear support. According to the aerial vehicle provided by the disclosure, the takeoff and landing power of the aerial vehicle is effectively improved and the maximum take-off weight and effective load of the aerial vehicle are improved by using multiple groups of lift motors on the aerial vehicle.

Claims (64)

1. A vertical takeoff and landing unmanned aerial vehicle, comprising:

a left main wing and a right main wing;

a main body which is engaged with the left main wing and the right main wing;

a left front wing and a right front wing which are engaged with the main body;

a left linear support which is engaged with the left main wing;

a first group of multiple lift propellers which are arranged on a top side of the left linear support;

a right linear support which is engaged with the right main wing;

a second group of multiple lift propellers which are arranged on a top side of the right linear support;

a left additional lift propeller which is arranged on a bottom side of the left linear support; and

a right additional lift propeller which is arranged on a bottom side of the right linear support; and

wherein a rotation coverage area of the left additional lift propeller overlaps with rotation coverage areas of two lift propellers in the first group of multiple lift propellers.

2. The vertical takeoff and landing unmanned aerial vehicle according to claim 1 , further comprising a left vertical stabilizer which is arranged at a tail end of the left linear support, and a right vertical stabilizer which is arranged at a tail end of the right linear support.

3. The vertical takeoff and landing unmanned aerial vehicle according to claim 2 , further comprising a top end lift propeller which is arranged at a top end of each of the left vertical stabilizer and the right vertical stabilizer.

4. The vertical takeoff and landing unmanned aerial vehicle according to claim 1 , further comprising two wingtip propellers, wherein the two wingtip propellers are respectively arranged at a distal end of the left main wing and the right main wing.

5. The vertical takeoff and landing unmanned aerial vehicle according to claim 4 , wherein one end, away from the main body, of each of the left main wing and the right main wing is provided with a wingtip vertical stabilizer, the wingtip vertical stabilizer is a plate-shaped structure which is vertically arranged and parallel to a longitudinal axis of the main body, each of the wingtip vertical stabilizer is respectively located on the left and right main wings and fixedly connected with the left and right main wings, and the two wingtip propellers are each arranged at a top end of the respective left and right wingtip vertical stabilizers.

6. The vertical takeoff and landing unmanned aerial vehicle according to claim 3 , further comprising a traction propeller which is arranged at a front end of the main body.

7. The vertical takeoff and landing unmanned aerial vehicle according to claim 1 , wherein the left main wing is connected to the left front wing through the left linear support, and the right main wing is connected to the right front wing through the right linear support.

8. The vertical takeoff and landing unmanned aerial vehicle according to claim 7 , further comprising a pod which is attached to a bottom side of the main body.

9. The vertical takeoff and landing unmanned aerial vehicle according to claim 8 , wherein the pod is a passenger pod.

10. The vertical takeoff and landing unmanned aerial vehicle according to claim 8 , wherein the pod is a cargo pod.

11. The vertical takeoff and landing unmanned aerial vehicle according to claim 1 , wherein a ratio of a weight increase percentage of the left additional lift propeller and the right additional lift propeller to an increase percentage of takeoff and landing power is 5-15%: 18-35%.

12. The vertical takeoff and landing unmanned aerial vehicle according to claim 11 , wherein a ratio of a weight increase percentage of the left additional lift propeller and the right additional lift propeller to a lift increase percentage is 5-10%: 18-30%.

13. The vertical takeoff and landing unmanned aerial vehicle according to claim 12 , wherein the ratio of the weight increase percentage of the left additional lift propeller and the right additional lift propeller to the lift increase percentage is 6%: 20-25%.

14. The vertical takeoff and landing unmanned aerial vehicle according to claim 13 , wherein the ratio of the weight increase percentage of the left additional lift propeller and the right additional lift propeller to the lift increase percentage is 6%: 22%.

15. A vertical takeoff and landing unmanned aerial vehicle, comprising:
