The invention discloses a multi-degree-of-freedom empennage for an ornithopter. The empennage comprises a body frame, a yawing and pitching steering engine, a yawing and pitching rudder arm, a central tailbone-imitating part, a roller steering engine, a tail end tailbone-imitating part, a tail feather folding and unfolding steering engine, a tail feather folding and unfolding rudder arm and tail feathers, wherein the yawing and pitching steering engine is mounted on the machine body frame and is integrally connected with the empennage through the yawing and pitching connecting rod; the rolling steering engine is mounted on the central tailbone-imitating piece, and a circular rudder arm is additionally mounted and matched with the rolling connecting piece to drive the torsion of the empennage surface; the tail feather folding and unfolding steering engine is installed on the tail end tailbone imitating piece, the tail feathers on the outer sides of the two ends are driven to be unfolded outwards or folded inwards by pulling the tail feather folding and unfolding connecting rod, and other tail feathers except the central tail feather are dragged to move through the tail feather linkage piece. Longitudinal, transverse and course movement of the aircraft body can be adjusted and controlled, and meanwhile folding and unfolding of the tail feathers can meet the requirements of the aircraft for different maneuverability.

    本发明公开了一种用于扑翼飞行器的多自由度尾翼,该尾翼包括机体架、偏航俯仰舵机、偏航俯仰舵臂、中央仿尾骨件、滚轴舵机、末端仿尾骨件、尾羽收展舵机、尾羽收展舵臂和尾羽;其中,偏航俯仰舵机安装在机体架上,通过偏航俯仰连杆与尾翼整体相连;滚转舵机安装在中央仿尾骨件上,通过加装圆形舵臂并与滚转连接件相配合来带动尾翼面的扭转;尾羽收展舵机安装在末端仿尾骨件上,通过拉动尾羽收展连杆带动两端外侧的尾羽向外展或向内收,通过尾羽联动件牵动除中央尾羽外的其余尾羽的运动。本发明不仅可以对机体的纵向、横向和航向运动进行调节控制,同时尾羽的收展可以适配飞行器对不同机动性的需求。
