民航运输飞机重着陆研究综述

飞行安全是民航运行的基础，飞机着陆时速度小、惯性大、运行环境复杂，是事故高发阶段。为了分析飞机重着陆研究现状，对国内外重着陆研究文献进行了评述。从仿真建模、机器学习等方法对重着陆智能诊断，利用定量分析法、定性分析法进行重着陆致因分析和风险评估，以及对重着陆的风险、数量和相关参数进行预测，对以上三个方面的现有研究的成果和不足进行了分析。由于飞行环境和人机交互过程中的复杂性、多变性、不确定性，民航飞机稳定控制系统和重着陆实时预测是未来的研究趋势。

Summary of Research on Civil Commercial Transport Aircraft Hard Landing

Flight safety is the foundation of civil aviation operations. The low speed, high inertia, and complex operating environment of an aircraft during landing are the stage where accidents occur frequently. In order to analyze the research status of aircraft hard landing, a review of domestic and foreign literature on hard landing was conducted. Simulation modeling, machine learning and other methods were used to analyze the intelligent diagnosis of hard landing, quantitative analysis and qualitative analysis were used to carry out hard landing causation analysis and risk assessment, and the risk, quantity and related parameters of hard landing were predicted. The results and deficiencies of the existing research on the above three aspects were analyzed. Due to the complexity, variability, and uncertainty in the flight environment and human-computer interaction, the stability control system and the real-time prediction of hard landing of civil aircraft are the future research trends.
