为确定舰载机最优阻拦定长冲跑控制规律,对美国MK7-3型液压阻拦机进行了动力学仿真,并采用Hicks-Henne形状函数和最速下降法对定长冲跑控制阀通流面积曲线进行了优化.对不同质量、进场速度和发动机推力的舰载机进行了阻拦仿真实验,结果表明:优化后的定长冲跑控制规律能使不同质量、进场速度和发动机推力的舰载机均在相同的阻拦距离上停下来,且钢索张力和舰载机加速度变化规律合理,证明了本文所述优化方法的合理性和安全性. In order to determine the optimum stopping and running control law of carrier-based aircraft, the dynamics simulation of American MK7-3 hydraulic blocker was carried out. The Hicks-Henne shape function and the steepest descent method were used to control the flow of the fixed-length run-on control valve Area curves were optimized.A block simulation experiment was carried out for carrier-based aircraft of different mass, approach speed and engine thrust.The results show that the optimized law of fixed-length running-on control can make the vehicle with different mass, approach speed and engine thrust The carrier-based aircraft stopped at the same stopping distance, and the law of the cable tension and the acceleration of carrier-based aircraft changed reasonably, which proves the rationality and safety of the optimization method described in this article.
