Document Type and Number:
WIPO Patent Application WO/2017/020763
Kind Code:
A1
Abstract:
An unmanned aerial vehicle comprises an aerial vehicle body (1), the aerial vehicle body (1) comprising a fuselage (2) and a storage device (4); aerial vehicle arms, the aerial vehicle arms comprising at least two front aerial vehicle arms (101) arranged symmetrically with respect to a central axis of the fuselage (2) in a front-rear direction, and at least two rear aerial vehicle arms (102) arranged symmetrically with respect to the central axis; rotor wing motors (93), the rotor wing motors (93) comprising front motors (93a) and rear motors (93b); one ends of the front aerial vehicle arms (101) are connected to the front end of the fuselage (2), and the other ends of the front aerial vehicle arms (101) are provided with the front motors (93a) for driving the unmanned aerial vehicle; one ends of the rear aerial vehicle arms (102) are connected to the rear end of the fuselage (2), and the other ends of the rear aerial vehicle arms (102) are provided with the rear motors (93b) for driving the unmanned aerial vehicle; intersection regions of extension lines, extending towards the fuselage (2), of the rear aerial vehicle arms (102) and extension lines, extending towards the fuselage (2), of the front aerial vehicle arms (101) are located in front of a center of dynamic lift of the unmanned aerial vehicle, and an action point of a resultant force of the front motors (93a) and the rear motors (93b) for the unmanned aerial vehicle is the center of dynamic lift; and a center of gravity of the unmanned aerial vehicle is adjacent to the center of dynamic lift. The unmanned aerial vehicle is reasonable in rack configuration and counter weight distribution, smooth and steady in flight and simple to control.
