The invention relates to a three-tandem-wing dual-mode tilting ducted vertical take-off and landing aircraft which comprises an aircraft body, wings arranged at the front section, the middle section and the rear section of the aircraft body and arranged in a bilateral symmetry mode, ducted propellers arranged at the ends of the three sections of the wings and an empennage, and the ducted propellers at the ends of the wings at the front section and the rear section of the aircraft body are fixedly connected with the corresponding wings. The ducted propellers at the ends of the wings of the middle section of the fuselage are in transmission connection with the corresponding wings, and the ducted propellers arranged on the four wings of the front section and the rear section provide vertical take-off and landing lift force and pitching moment in the flight state for the aircraft. The ducted propellers arranged on the middle-section wings provide extra thrust for the aircraft in a flying state; the problems of low lift-drag ratio and high energy consumption caused by pneumatic interference or redundant layout of the current aircraft are solved; a distributed power system aggravates flow field disorder, and flight stability is influenced; when a conventional tilting aircraft is switched between a vertical take-off and landing mode and a level flight mode, power distribution is uneven, and pitching torque unbalance is prone to being caused.

    本发明涉及一种三串列翼双模式倾转涵道垂直起降飞行器,包括机身、设置在机身前中后三段处且左右对称布置的机翼、装设在三段机翼端部的涵道螺旋桨以及尾翼,机身前后段机翼端部的涵道螺旋桨与对应机翼固定连接,机身中段机翼端部的涵道螺旋桨与对应机翼传动连接,四个前后段机翼配置的涵道螺旋桨为飞行器提供垂直起降的升力和飞行状态的俯仰力矩;中段机翼配置的涵道螺旋桨为飞行器提供飞行状态时的额外推力;解决了当前飞行器因气动干扰或冗余布局导致升阻比低、能耗高;分布式动力系统加剧流场紊乱,影响飞行稳定性;常规倾转飞行器在垂直起降与平飞模式转换时,动力分配不均,易引发俯仰力矩失衡的问题。
