舰载机综合复飞决策研究

Research on comprehensive wave-off decision of carrier-based aircraft

舰载机在着舰过程中,由于种种干扰偏离理想下滑轨迹后,飞行员必须及时准确地作出复飞决策并采取相应的动作。针对这一问题,对已有的复飞下边界准则进行了进一步的完善,并推导和确定了复飞上边界准则。然后首次将基于小扰动动力学模型的着舰系统与基于终端预估方程的复飞决策系统相结合,设计了基于改进型复飞边界准则的综合复飞决策系统,得到了相应的综合复飞区及复飞边界,并针对不同着舰情况对综合复飞决策系统进行了仿真验证。结果表明,该系统能够及时判断出舰载机是否进入复飞区,复飞是否安全,从而大大提高了舰载机的着舰效率和着舰安全性。

After carrier-based aircraft deviates from ideal glide path due to several disturbances during landing, the pilot must make wave-off decision in time and take some actions. The perfect wave-off lower boundary criteria are presented in this paper, and upper boundary criteria are also deduced and defined. Combined wave-off decision system based on small perturbation equations with wave-off decision system based on terminal prediction equations, the comprehensive wave-off decision system based on improved wave-off boundary criteria are designed in this paper for the first time, from which the wave-off zone and wave-off boundary can be obtained. Besides, the simulation resuits of this system for different landing status are presented in this paper. The results indicate that this new system can judge whether it is in wave-off zone and whether it is safe, so that it can ensure the efficiency and safety of aircraft landing more effectively.
