The invention discloses a combined type vertical take-off and landing long-endurance electric unmanned aerial vehicle, which belongs to the field of unmanned aerial vehicles. According to the combined type vertical take-off and landing long-endurance electric unmanned aerial vehicle, the fuselage adopts the wing body fusion body, the wetted area of the unmanned aerial vehicle can be reduced by removing unnecessary exposed parts of the fuselage, so that the frictional resistance is reduced, and the lift-drag ratio of the unmanned aerial vehicle is increased by reducing parts irrelevant to lift force in the wing body fusion layout. The winglet is adopted, the end plate effect of the winglet is utilized, and the equivalent aspect ratio of the aircraft is increased under the condition that the wingspan increase is small. The double-tail-boom empennage layout is adopted, the lateral stability of the unmanned aerial vehicle can be improved, and the structural support is good. The lift-drag ratio aerodynamic layout is improved through the structural design of the unmanned aerial vehicle, so that the endurance performance of the aircraft is improved.

    本发明公开了一种复合式垂直起降长航时电动无人机,属于无人机领域。本发明的复合式垂直起降长航时电动无人机,机身采用翼身融合体,去除不必要的机体外露部件即可减少飞机的浸湿面积,从而减少摩擦阻力,翼身融合布局通过减少与升力无关的部件从而达到提高无人机的升阻比;本发明采用翼梢小翼,利用翼梢小翼的端板效应,在翼展增加较小的条件下增大了飞机的当量展弦比。本发明采用双尾撑尾翼布局,可以提高无人机的侧向安定性,结构支撑较好。本发明通过无人机结构设计来提高升阻比气动布局,从而增加飞机续航性能。
