The invention discloses a distributed electric propulsion tilt rotor unmanned aerial vehicle. According to the aircraft, a three-section fixed type wing overall layout is adopted; front wings and rearwings are arranged in two layers; the wings in the upper and lower layer are each provided with electric propulsion ducted fans; a middle wing is mainly used for generating lift force when fixed wings fly; the ducted fans serve as a power system, and thrust generated by the ducted fans is used for achieving the vertical take-off and landing, hovering and fixed wing patrolling of the aircraft; tilting mechanisms are arranged at the joints of the front wings, the rear wings and an aircraft body so as to achieve mutual switching between a vertical take-off & landing and hovering mode and a fixedwing patrolling mode. When the aircraft has the speed required for patrol flight, transition from the vertical take-off & landing and hovering mode to the fixed wing mode is completed. According to the distributed electric propulsion tilt rotor unmanned aerial vehicle of the invention, the distributed electric propulsion ducted fans are adopted as the aircraft power system, and therefore, the size and weight of the power system are reduced, the redundancy and reliability of the power system are improved; and a ducted fan rotating speed differential mode is adopted during fixed wing patrollingflight, so that control efficiency can be improved.

    本发明公开了一种分布式电推进倾转旋翼无人飞行器。飞行器采用三段机翼式固定翼总体布局,前、后机翼均采用两层布置,上下层机翼各设置有电推进涵道风扇,中机翼主要用于固定翼飞行时产生升力。涵道风扇作为动力系统,其产生的推力用于实现飞行器的垂直起降、空中悬停及固定翼巡飞,前后机翼和机身的结合处设置有倾转机构,以实现垂直起降和空中悬停模式与固定翼巡飞模式间相互切换。当飞行器具备巡飞需用速度时,完成从垂直起降和空中悬停模式过渡至固定翼模式。该发明采用了分布式电推进涵道风扇作为飞行器动力系统,减小了动力系统尺寸及重量,提高了动力系统冗余度及可靠性,固定翼巡飞时采用涵道风扇转速差动方式,可进一步提高控制效率。
