The invention relates to the technical field of aviation, in particular to a high-speed electric vertical take-off and landing aircraft with foldable wings and a flight method. In the vertical take-off and landing stage, the outer side section wings are perpendicular to the ground, the downward load generated by downward washing of the rotor wings can be effectively reduced, and the hovering efficiency is improved; in the high-speed front flight stage, the lift-drag ratio of the whole aircraft is further improved through the outwards-extending small wings, and the cruising performance is improved. According to the six-rotor multi-redundancy design, insufficient power caused by single-engine or double-engine failure of the motor can be avoided, in addition, transition between a vertical take-off and landing mode and a high-speed forward flight mode is achieved through the front rotor, the middle rotor and the rear rotor in a step-by-step tilting mode, and a transition flight corridor is expanded as much as possible. The rotors are driven by the motors, only total pitch control is reserved, point-to-point high-speed flight among cities can be achieved without a runway, the effective load can be further improved in a taxiing takeoff mode, and the adaptability to the complex urban traffic environment is high.
本发明涉及航空技术领域,具体涉及一种可折叠机翼高速电动垂直起降飞行器及飞行方法。本发明在垂直起降阶段,外侧段机翼垂直地面,可有效降低旋翼下洗流产生的向下载荷,提升悬停效率;在高速前飞阶段,通过外伸小翼进一步提高全机升阻比,提升巡航性能。本发明六旋翼多冗余设计可避免电机在单发或双发失效时造成的功率不足,此外,前、中、后三组旋翼采用分步倾转的方式实现垂直起降模式和高速前飞模式间的过渡,尽可能扩大过渡飞行走廊。本发明各旋翼通过电机驱动,且只保留总距操纵,本发明既可不借助跑道实现城市间“点对点”高速飞行,也可通过滑跑起飞方式进一步提升有效载荷,对复杂城市交通环境适应性较强。
