The invention discloses a vertical take-off and landing unmanned aerial vehicle and a control method thereof. The unmanned aerial vehicle comprises a wing body fusion fuselage, a power system and an undercarriage, and the power system comprises turbofan engines and lift fan engines; the wing body fusion fuselage adopts a structure which is symmetrical along the longitudinal axis and the transverseaxis of the overlooking plane; the two turbofan engines are symmetrically and externally connected to the left side and the right side of the wing body fusion fuselage, and the turbofan engines are connected with the wing body fusion fuselage through tilting transmission mechanisms; the two lift fan engines are symmetrically buried at the front end and the rear end of the wing body fusion fuselage. The control method comprises the following five stages of stage 1, vertical take-off and hovering, stage 2, hovering in the air and performing level flight, stage 3, level flight, stage 4, level flight-hovering in the air, and stage 5, hovering in the air and vertically landing. When the unmanned aerial vehicle takes off and lands vertically, lift force and auxiliary balance are provided by thefour engines, the aircraft is low in control difficulty and large in internal space of the fuselage, and the problems that an existing vertical take-off and landing unmanned aerial vehicle is difficult to control and small in load capacity are solved.

    一种垂直起降无人机及其控制方法,无人机包括翼身融合体机身、动力系统及起落架,动力系统包括涡扇发动机和升力风扇发动机;翼身融合体机身采用沿俯视平面的纵轴和横轴均对称的结构;两台涡扇发动机对称外接在翼身融合体机身左右两侧,涡扇发动机通过倾转传动机构与翼身融合体机身相连;两台升力风扇发动机对称埋设在翼身融合体机身前后两端。控制方法包括五个阶段,阶段一:垂直起飞→空中悬停;阶段二:空中悬停→平飞;阶段三:平飞;阶段四:平飞→空中悬停;阶段五:空中悬停→垂直降落。无人机垂直起降时,由四台发动机提供升力及辅助平衡,飞行器控制难度低且机身内部空间大,解决了现有垂直起降无人飞行器的控制困难与载重量小的问题。
