Abstract
A vertical takeoff and landing aerial vehicle, including a plurality of lift propellers. A rotating shaft of each lift propeller from among the multiple lift propellers outwards forms an angle of 5 degrees to 15 degrees relative to a vertical plane of the aerial vehicle perpendicular to a horizontal plane of the aerial vehicle. The aerial vehicle of the present disclosure improves the heading axis control capacity of the aerial vehicle and reduces the restriction to the design size of the aerial vehicle.
Claims14
A vertical takeoff and landing unmanned aerial vehicle, comprising:
- a main body;
- a left main wing and a right main wing which are respectively engaged with the main body;
- a left front wing and a right front wing which are respectively engaged with the main body;
- a left linear supporting piece arranged on the left main wing;
- a right linear supporting piece arranged on the right main wing;
- a first group of multiple lift propellers arranged on the left linear supporting piece;
- and
- a second group of multiple lift propellers arranged on the right linear supporting piece;
- wherein an outwards deflecting included angle less than 90 degrees is provided between a rotating shaft of each of the first group of multiple lift propellers and a plane in a lengthwise direction of the unmanned aerial vehicle;
- and an outwards deflecting included angle less than 90 degrees is provided between a rotating shaft of each of the second group of multiple lift propellers and the plane in the lengthwise direction of the unmanned aerial vehicle;
- wherein the included angle between the rotating shaft of each lift propeller from among the first group of multiple lift propellers and the second group of multiple lift propellers and the plane in the lengthwise direction of the unmanned aerial vehicle is 5 degrees to 15 degrees;
- and
- wherein included angles between two adjacent lift propellers in the first group of multiple lift propellers and the plane in the lengthwise direction of the unmanned aerial vehicle are different, and included angles between two adjacent lift propellers in the second group of multiple lift propellers and the plane in the lengthwise direction of the unmanned aerial vehicle are different.
