Description

technical field

[0001] The invention belongs to the technical field of aircraft gust mitigation control, and in particular relates to a gust response modeling analysis method of a fixed-wing aircraft. Background technique

[0002] There are complex airflow movements in the atmosphere, and fixed-wing aircraft are susceptible to these disturbances when flying in it. Among them, the vertical gust will not only cause a large overload of the aircraft, generate a large dynamic structural load, accelerate structural fatigue damage, but also reduce the flight quality of the aircraft, which is not conducive to the normal operation of airborne equipment. Therefore, when designing an aircraft, it is necessary to establish a gust response model of the aircraft and analyze its gust response characteristics in order to design gust mitigation control.

[0003] Guo Shijun of Clayfield University and Li Daochun of Beihang University have studied a passive gust mitigation device. The device...
