摘要
现代作战飞机普遍采用机载制氧系统,同时配备备用氧以保障特殊情况下的飞行安全。所设置的备用氧量应能够满足使用和安全需要,同时还要避免增大空间需求和重量。本文在空勤人员氧气量需求一般分析方法基础上,针对需要应急供氧的不同特情进行了处置方法、任务变更措施分析,据此计算了需要的备用氧量。给出的特情处置原则和方法可用作同类型飞机确定备用氧量时的参考和指导。
Modern combat aircrafts are commonly equipped with onboard oxygen generation system, and meanwhile with backup oxygen to satisfy aircrews demand in emergency situation. The backup oxygen quantity should be sufficient for use and safety, and the demanded onboard installation room and weight of the system should be as small as possible. Based on the method of oxygen requirement general analysis, the paper analyzed the measures of treatment and mission change for various special situations in which the backup oxygen will be used, and furthermore, calculated the backup oxygen volume. The principles and methods could be a reference and guide to determine the demanded backup oxygen volume for the same type aircraft.
