ORNITHOPTER

PROBLEM TO BE SOLVED: To provide an ornithopter having excellent mimesis performance and capable of suppressing thrust loss and resistance increase.SOLUTION: The ornithopter comprises: a main wing attached to a shell 2; and a control system for controlling flap operation of the main wing. The main wing has an inner girder 21, an outer girder 22, and a wrist 30 interposed between the inner and outer girders and configured so that a folding angle which is a relative angle between the inner and outer girders can be varied within a predetermined variation range. The control system has an actuator 120 for performing launch operation and low hit operation of the inner girder by making the inner girder move in a vertical direction, an angle sensor 140 for measuring the folding angle, and a control device 110 for operating the inner girder by controlling the actuator according to the folding angle.
