According to the star-shaped propeller pitching and heading control device, a lower star arm connecting lug, a left oblique star arm connecting lug and a right oblique star arm connecting lug which are vertically downward are arranged outside a machine arm base of a star arm machine arm connecting base, and the included angle between every two adjacent star arm connecting lugs is 120 degrees; a lower star arm, a lower motor mounting seat, a lower motor and a lower propeller are sequentially connected to a lower star arm connecting lug, a left oblique star arm, a left oblique motor mounting seat, a left oblique motor and a left oblique propeller are sequentially connected to a left oblique star arm connecting lug, and a right oblique star arm, a right oblique motor mounting seat, a right oblique motor and a right oblique propeller are sequentially connected to a right oblique star arm connecting lug. The device is used for controlling the pitching and course of the aircraft, the pitching is controlled by differential motion of the lifting force of the lower propeller and component force of the left inclined propeller and the right inclined propeller in the vertical direction, the course is controlled by differential motion of component force of the left inclined propeller and the right inclined propeller in the horizontal direction, the course is controlled by adopting torque, and the angle between the lifting force of the lower propeller and the included angle between the lifting force of every two adjacent propellers is 120 degrees. And the capability is higher than that of controlling the course by adopting reaction torque.
一种星型螺旋桨俯仰和航向控制装置,星臂机臂连接座的机臂座外分别是垂直向下的下星臂连接耳、左斜星臂连接耳、右斜星臂连接耳,相邻两个星臂连接耳的夹角是120°;下星臂、下电机安装座、下电机、下螺旋桨顺序连接在下星臂连接耳上,左斜星臂、左斜电机安装座、左斜电机、左斜螺旋桨顺序连接在左斜星臂连接耳上,右斜星臂、右斜电机安装座、右斜电机、右斜螺旋桨顺序连接在右斜星臂连接耳上,相邻两个螺旋桨的升力的夹角是120°,该装置用于操纵飞行器的俯仰和航向,下螺旋桨的升力和左斜螺旋桨、右斜螺旋桨在垂直方向的分力的差动操纵俯仰,左斜螺旋桨与右斜螺旋桨在水平方向的分力差动操纵航向,采用力矩操纵航向,比采用反扭矩操纵航向的能力强。
