The invention relates to the technical field of aircrafts, aims to solve the problem that wings of an existing ornithopter cannot be directly controlled to generate rolling torque, and provides an ornithopter and a rolling flight method thereof.The ornithopter comprises an ornithopter body, the wings are symmetrically installed on the two sides of the ornithopter body, and transverse straight beams and skins are arranged on the wings; one end of the transverse straight beam is connected with the fuselage, and the skin is connected between the transverse straight beam and the fuselage and covers the wings; the transverse straight beam is divided into a first beam and a second beam, one end of the first beam is connected with the machine body, and the other end of the first beam is hinged to the second beam; a plurality of supporting rods are connected to the skin, one end of each supporting rod is connected to the hinge point of the first cross beam and the second cross beam, and all the supporting rods are unfolded in a fan shape; a telescopic device is connected between the second cross beam and the machine body; the method comprises the following steps: controlling the telescopic device to stretch out and draw back, changing the length of the telescopic device, changing the opening area of the skin on the wings on the two sides, and generating a rolling moment by utilizing a lift force difference generated by the wings on the two sides, thereby realizing rolling flight of the ornithopter.

    本发明涉及飞行器技术领域,旨在解决现有的扑翼飞行器机翼不能直接被控制产生滚转力矩的问题,提供一种扑翼飞行器及其滚转飞行方法,扑翼飞行器包括机身,机身的两侧对称安装有机翼,机翼上设有横直梁和蒙皮,横直梁的一端连接机身,蒙皮连接在横直梁与机身之间,覆盖机翼;横直梁分为第一横梁和第二横梁,第一横梁的一端连接机身,第一横梁的另一端与第二横梁铰接;蒙皮上连接有多根支杆,每根支杆的一端均连接至第一横梁与第二横梁的铰点,所有支杆呈扇形展开;第二横梁与机身之间连接有伸缩装置;方法包括通过控制伸缩装置伸缩,改变其长度,改变两侧机翼上蒙皮的张开面积,利用两侧机翼产生的升力差,产生滚转力矩,实现扑翼飞行器滚转飞行。
