Abstract：Different from conventional wings, the bird strike device of the variable camber wing needs to consider the movement route of the variable camber wing during the design, so as to ensure that the normal function of the wing mechanism is not affected. Therefore, it also greatly increases the difficulty of the design of the bird strike device. In this paper, the bird-strike resistance performance of wedge-shaped structures of different configurations is studied through the method of combining experiment and simulation, and the most reasonable and effective anti-bird strike structure is obtained. According to the results of bird strike simulation, combined with the movement route of the wing mechanism, the design idea of the bird strike device is determined. The triangle and arc anti bird strike device is designed and manufactured, and the experimental verification and simulation analysis are carried out. The results show that the triangle and arc structure can effectively prevent the variable camber wing from being damaged after being hit by bird, which provides a reference for the design of the anti-bird strike structure of the wing.
