The invention belongs to the technical field of aviation, and particularly relates to a rotor wing tilting mechanism of an electric vertical take-off and landing aircraft and a working method. According to the tilting mechanism, the whole tilting mechanism is arranged in a bilateral symmetry mode, in addition, the left side component and the right side component are connected through the concentric shaft which is transversely arranged, the strength and rigidity of the whole tilting mechanism in the movement process are enhanced, vibration in the complex flight state can be effectively reduced through stable mechanical arrangement, and the tilting precision is guaranteed. A unique connecting rod mechanism is adopted, so that the tilting rotor wings in the middle sections of the wings only tilt blades, a cabin body mechanism where the rotor wings are located does not need to integrally tilt, and a power redundancy design driven by double linear motors is adopted; the tilting mechanism provides a new tilting mode selection for the tilting type electric vertical take-off and landing aircraft, avoids the problems of wing additional lower washing load caused by overall tilting of the nacelle and unstable large stall attack angle of the wing tilting mode, and is beneficial for the aircraft to give full play to the advantages of vertical take-off and landing, high-speed forward flight and the like.
本发明属于航空技术领域,具体涉及一种电动垂直起降飞行器旋翼倾转机构及工作方法。本倾转机构总体呈左右对称布置,此外,左侧部件和右侧部件之间通过横向布置的同心轴连接,增强了整套倾转机构在运动过程中的强度和刚度,稳固的机械布置也可有效降低复杂飞行状态下的振动,保证倾转精度。本发明采用独特的连杆机构使得机翼中段的倾转旋翼仅倾转桨叶,无需使旋翼所在舱体机构整体倾转,采用了双直线电机驱动的动力冗余设计;本倾转机构为倾转类电动垂直起降飞行器提供了新的倾转方式选择,避免了短舱整体倾转引起的机翼附加下洗载荷、机翼倾转形式的大失速迎角不稳定问题,有利于该型飞行器充分发挥垂直起降和高速前飞等优点。
