The invention provides a dual-mode take-off and landing four-tilt rotorcraft, and belongs to the technical field of manned aircrafts, the dual-mode take-off and landing four-tilt rotorcraft comprises a fuselage, two front wings are symmetrically arranged on the two sides of the head of the fuselage, and front rotors are arranged at the ends of the fuselage; the two rear wings are symmetrically arranged on the two sides of the tail of the fuselage, and rear rotors are arranged at the ends; when the four rotors tilt to face the head of the fuselage, the lowest ends of the four rotors are flush with the lowest end of the fuselage or higher than the midpoint position of the landing gear in the open state, and therefore the four rotors have the vertical take-off and landing capacity and the horizontal take-off and landing capacity at the same time; in addition, through equal-lift wings and a zero-interference four-rotor structure, better balance is formed by a free pneumatic center and mass center matching structure, and the control difficulty is reduced; a plurality of downwash pneumatic optimization and drag reduction structures are designed, so that the maximum speed and the cruising speed of the classic tilt rotorcraft are increased by more than 20%; cleanness, electrification and intellectualization are achieved through a distributed motor, a liquid hydrogen fuel cell, a lifting and horizontal transition automatic model and the like.

    本发明提供的双模起降四倾转旋翼机,属于载人飞行器技术领域,包括:机身,两个前机翼对称设置在机身头部两侧,端部设置有前旋翼;两个后机翼对称设置在机身尾部两侧,端部设置有后旋翼;当四旋翼均倾转至朝向机身的头部时其最低端与机身的最低端平齐或者高于打开状态起落架的中点位置,因此同时具备垂直起降和水平起降的能力;另外通过等升力机翼和零干扰四旋翼结构、自由气动中心与质心匹配结构形成更好的平衡性并降低了操控难度;设计多个下洗气动优化和减阻结构将经典倾转旋翼机的最高速度和巡航速度提升了大于20%;通过分布式电机、液氢燃料电池、起降和水平过度自动模型等实现了清洁化、电气化和智能化。
