摘　　要：某型飞机需要进行大迎角试飞,以验证防偏离尾旋功能,须考虑进入、改出尾旋的意外情况。进入尾旋后,如果飞机双发停车,应急液压系统应具有足够的压力、流量及工作时间满足飞控系统各操纵面偏转需求,顺利改出尾旋并安全着陆。本文利用西门子公司的LMS Imagine.Lab AMESim(简称AMESim)软件和Matlab/Simulink软件对液压部件和飞机进入、改出尾旋的状态进行建模仿真,计算飞行控制系统各操纵面液压部件的液压流量需求情况。High-AOA flight test of XX aircraft is implemented to verify its anti-departure and anti-spin function. Consideratinns must be given to the contingencies while entering and recovering from spin. In case of dual-engine shutdown when aircraft enters a spin, the emergency hydraulic system should he ahle to provide sufficient hydraulic pressure, flow and operation time to meet the requirements of flight control system to deflect each control surface, thus enabling a successful recovery from spin and ensuring a safe landing. This paper, with the application of LMS Imagine.Lah AMESim software （AMESim for short） and Matlab/Sinmlink software, studies the modeling and simulation fer hydraulic components and the states when the farcraft enters and recovers from a spin, calculates hydraulic fluid flow demand of hydraulic components in each control sm＇face of flight control system.
