The invention discloses a graded early warning method and system for safety lifesaving of an ejection seat, and the method comprises the steps: calculating a track of a human-chair system, extracting a minimum safety height as an output value, building a flight parameter input-minimum safety height output database, training an artificial intelligence algorithm of the database, and carrying out the calculation of the minimum safety height. The method comprises the following steps: acquiring a safety lifesaving envelope model of an ejection seat, performing sensitivity analysis and screening on flight parameters, and then performing iteration and optimization on the safety lifesaving envelope model of the ejection seat to obtain a final safety lifesaving envelope proxy model of the ejection seat; and warning and warning signals are respectively given according to the danger degree of safe lifesaving of the pilot. The method and the system can predict the safety ejection risk, provide ejection opportunity control for the pilot, and have outstanding significance for guaranteeing aviation safety and saving the life of the pilot.

    本发明公开了一种用于弹射座椅安全救生的分级预警方法及系统,该方法对人椅系统的轨迹进行计算,提取出最低安全高度作为输出值,建立“飞行参数输入‑最低安全高度输出”数据库,对数据库人工智能算法进行训练,得到弹射座椅安全救生包线模型,对飞行参数进行敏感度分析和筛选,然后对弹射座椅安全救生包线模型进行迭代和优化,得到最终的弹射座椅安全救生包线代理模型;根据飞行员安全救生的危险程度分别给出警戒和警告信号。本方法和系统可以预测安全弹射风险,为飞行员提供弹射时机控制,对保障航空安全和挽救飞行员的生命具有突出的意义。
