舰载机复飞决策方法仿真研究

Research on Wave-off Decision Simulation of Carrier-Based Aircraft

在舰载机着舰复飞过程安全性问题的研究中,由于舰载机是在复杂的环境下着舰,会偏离理想下滑轨迹。为保证着舰的安全性,提出了一种安全飞行区域和安全复飞区域相对位置关系的复飞决策方法以提高复飞安全性。建立驾驶员-舰载机系统模型,在定义安全飞行准则的基础上,依据尾钩落点分布和舰尾净高指标,采用仿真手段确定纵向回路安全飞行区域;分析不同距舰距离复飞风险特异性,定义甲板净高和海面净高的概念,制定多因素综合安全复飞区域。明确上述两区域相对位置关系,建立着舰指挥官复飞辅助决策系统。仿真结果表明,提出的复飞决策方法切实可行,设计的复飞决策系统实用可靠,为舰载机着舰安全性的提高奠定了理论基础。

In allusion to the high risk of landing on carrier and wave-off, a new wave-off decision method for im- proving safety was proposed based on the relationship between Safe Flight Area （SFA） and Safe Wave-Off Area （SWA）. The conception of safe flight criteria was defined. Longitudinal SFA was determined by simulation, accord- ing to distribution of touchdown points and hook-to-ramp clearance. SWA based on multi-factor was found through analyzing the specific of wave-off risks among different distances and defining the conceptions of deck clearance and sea clearance. The relative position above the areas was clear, and the Landing Signal Officer wave-off decision sys- tem was established finally. The simulation results show that the wave-off decision method is feasible. Furthermore, the designed system is practical and reliable. This method forms a theoretical basis for safety of carrier-based aircraft landing task.
