The invention discloses a distributed tilting multi-rotor aircraft and a flight control method, and aims to reduce structures such as ailerons, flaps, rudders and the like of the aircraft and improve a control effect. According to the technical scheme, the distributed tilting multi-rotor aircraft comprises a fuselage, main wings, auxiliary wings, distributed tilting power systems, a vertical empennage and an elevator, wherein the main wings and the auxiliary wings form tandem wings; and the distributed tilting power systems are fixed to the front edges of the main wings and the auxiliary wings and there are at least six sets of the distributed tilting power systems, control optimization is achieved through a step-by-step tilting control strategy, multi-flight-mode switching is achieved, a multi-rotor-wing vertical take-off and landing mode, a fixed-wing high-speed cruising mode and a composite-wing fusion task mode are included, and the extremely high free control capacity of the aircraft is achieved. A distributed tilting multi-rotor power system is adopted as a control device, the structures such as ailerons, flaps, rudders and the like in a fixed wing mode are reduced, and the control functions of rolling, lift augmentation/deceleration and yawing are achieved instead of the structures.
本发明公开了一种分布式倾转多旋翼飞行器及飞行控制方法,减少了飞行器副翼、襟翼、方向舵等结构,提高控制效果。其技术方案要点是分布式倾转多旋翼飞行器包括机身、主机翼、副机翼、分布式倾转动力系统、垂直尾翼、升降舵,主副机翼形成串列翼;所述的分布式倾转动力系统固定于主机翼、副机翼的前缘,并包括至少6套,通过分步的倾转控制策略实现控制优化,实现多飞行模式切换,包括多旋翼垂直起降模式、固定翼高速巡航模式、复合翼融合任务模式,实现飞行器极高的自由控制能力;采用分布式的倾转多旋翼动力系统作为控制装置,减少固定翼模式下的副翼、襟翼、方向舵等结构,代替其实现滚转、增升/减速、偏航的控制功能。
