The invention discloses a flight mode control method of a distributed tilting multi-rotor aircraft. The function of switching control of three flight modes of a single aircraft is achieved. According to the technical scheme, the distributed tilting multi-rotor aircraft is characterized in that the distributed tilting multi-rotor aircraft is provided with at least six sets of distributed tilting power systems, switching of multiple flight modes including a multi-rotor flight mode, a fixed wing flight mode and a composite wing flight mode can be achieved, and flight mode control is achieved by changing the power directions of the tilting power systems through tilting mechanisms. In the flight mode conversion process, the control system sequentially controls the symmetric tilting mechanisms to achieve paired step-by-step tilting of the tilting power systems, and the control system cooperatively controls the tilting actions of the tilting mechanisms and the rotating speed of the rotors. In the tilting process, the tilting power systems implement a stalling-tilting-restarting scheme. The task adaptability of the aircraft is greatly improved through the multi-flight mode, and future multi-functionalization of the aircraft is achieved.
本发明公开了一种分布式倾转多旋翼飞行器的飞行模式控制方法,实现了单一飞行器的三种飞行模式切换控制的功能。其技术方案要点是所述的分布式倾转多旋翼飞行器拥有分布式倾转动力系统至少6套,可实现多飞行模式切换,包括多旋翼飞行模式、固定翼飞行模式、复合翼飞行模式,所述的飞行模式控制由倾转机构改变倾转动力系统动力方向实现。在飞行模式转换过程中,所述的控制系统通过依次控制对称的每组倾转机构实现各倾转动力系统的成对分步倾转,且所述的控制系统将协同控制倾转机构的倾转动作及旋翼的转动速度。在倾转过程中,倾转动力系统实施停转‑倾转‑再启动方案。多飞行模式极大的提高了飞行器的任务适应性,实现飞行器未来的多功能化。
