Flapping wing aircraft and rolling flight method thereof

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 un
