The invention relates to the technical field of unmanned aerial vehicle equipment, in particular to a rotor tilting device for a coaxial dual-rotor aircraft. The rotor tilting device comprises a pair of adjusting assemblies used for pushing the blades to turn over in the horizontal plane, a first steering engine and a second steering engine. The adjusting assembly and a main shaft of the coaxial dual-rotor aircraft are coaxially arranged. The pair of adjusting assemblies are symmetrically arranged on the two sides of the fixing frame, and the first steering engine and the second steering engine form linkage inclined overturning adjustment on the upper rotor wing assembly and the lower rotor wing assembly through the pair of adjusting assemblies. A swash plate of the adjusting assembly is connected with the main shaft through a fisheye bearing, and the side wall of the swash plate is sleeved with a connecting piece. The swash plate is connected with the first steering engine and the second steering engine through connecting rods. And the ball head pull rod is arranged on the side wall of the connecting piece. According to the rotor tilting device for the coaxial dual-rotor aircraft, the complexity of a dynamic model of the aircraft is reduced, the aerodynamic interference between the dual rotors is reduced, and the controllability of the attitude of a fuselage and the flight stability are improved.
本发明涉及无人机设备技术领域,具体涉及一种用于共轴双旋翼飞行器的旋翼倾斜装置。该旋翼倾斜装置包括一对用于推动桨叶在水平面内进行翻转的调节组件、第一舵机和第二舵机。调节组件与共轴双旋翼飞行器的主轴同轴布设。一对调节组件在固定架的两侧呈对称布设,第一舵机和第二舵机均通过一对调节组件对上旋翼组件和下旋翼组件形成联动倾斜翻转调整。调节组件的倾斜盘通过鱼眼轴承与主轴相连,连接件套设在倾斜盘的侧壁上。倾斜盘通过连杆分别与第一舵机和第二舵机相连。球头拉杆安装在连接件的侧壁上。该用于共轴双旋翼飞行器的旋翼倾斜装置降低飞行器的动力学模型的复杂度,减少双旋翼之间的气动干扰,提高对机身姿态的可控性以及飞行稳定性。
