The invention belongs to the technical field of aviation aircraft design, and discloses a vertical take-off and landing tilting lift fan unmanned aerial vehicle with compact layout, which comprises a lift body fuselage, a balancing lift fan, a right main lift fan, a left main lift fan, a right wing, a left wing, a right empennage and a left empennage. Through reasonable arrangement and combination of the lift surface and the lift device, the problem that the high-lift airfoil profile head lowering moment is large is solved through the nose lift fan, positive lift cruise trimming similar to duck-type layout is achieved, and the take-off weight is increased; the slip flow of the main lift fan is fully utilized, the slip flow lift augmentation effect is achieved, and the cruise lift is increased; under strict layout size constraints, the maximum take-off weight, cruising speed and voyage of existing equipments of the same size are far higher than those of existing equipments of the same size.

    本发明属于航空飞行器设计技术领域,公开了一种紧凑布局的垂直起降倾转升力风扇无人机,包括升力体机身、配平升力机扇、右主升力风扇、左主升力风扇、右机翼、左机翼、右尾翼和左尾翼。本发明通过合理的升力面、升力装置布置组合,采用机头升力风扇解决了高升力翼型低头力矩较大问题,实现类似鸭式布局的正升力巡航配平,提升了起飞重量;充分利用主升力风扇滑流,起到滑流增升作用,增加巡航升力;能够在严苛的布局尺寸约束下,实现了远超现有同尺寸装备最大起飞重量、巡航速度与航程。
