根据飞机座舱迅速减压导致飞行员肺损伤的机理,考虑了飞行员呼吸状态和呼吸道通畅程度等生理因素对迅速减压峰值的影响,建立了迅速减压肺损伤非刚性仿真模型,利用C++编程实现仿真计算和结果显示.分析了肺内压强变化趋势以及肺内减压峰值变化规律.运用实验数据及文献实例对此模型进行了验证.通过对不同减压条件下肺内减压峰值进行预测和分析,划分了不同迅速减压条件下减压峰值区域.基于此模型对3种典型的飞机(战斗机、轰炸机、客机)座舱迅速减压特点进行了分析.结果对飞行员及民航旅客的生命安全保障及防护装备的设计有参考价值.
According to the mechanism of pilots’ lung injury caused by the rapid decompression of the cockpit, the impact of physiological factors such as pilot’s breathing state and airway patency on the rapid decompression peak was considered. A non-rigid simulation model of rapid decompression lung injury was established and simulated by C ++ programming Computation and results show that the change trend of intrapulmonary pressure and the change law of peak value of intrapulmonary decompression are analyzed.The experimental data and literature examples are used to validate this model.Predicting and analyzing the peak value of intrapulmonary decompression under different decompression conditions , Divided into different areas under rapid decompression peak pressure relief.Based on the model of three typical aircraft (fighter, bomber, passenger aircraft) rapid decompression cockpit characteristics were analyzed.Results for pilots and civil aviation passengers safety and life protection and Protective equipment design has reference value.
