飞行环境综合因素对飞机供氧参数的影响

飞行环境综合因素对飞行员的影响，尤其是对飞行员氧气防护装备性能参数的作用未见报道。本文测试了低空大速度飞行试验条件下飞行紧张因素对飞行员呼吸系统的影响。结果表明，尽管飞行过载是飞行劳动中的重要生理负荷，但低空大速度飞行时飞行员的心理工作负荷是飞行中更重要的精神负荷，高度的精神负荷致使飞行员通气和瞬时需氧量明显增加，高达２５５Ｌ／ｍｉｎ，应当引起高度的重视。这对设计和计算飞机氧气呼吸装备的耗氧量，载

EFFECTS OF INFLIGHT ENVIRONMENT MULTIPLE FACTORS ON THE PARAMETER OF AIRCRAFT OXYGEN EQUIPMENT

The effects of the multiple factors in flight environment on pilots,especially on the parameters of pilots' Oxygen protective equipment have not reported.The effects of the mental tense factor in high speed flight tests at lower altitude on pilots' respiratory system are reported in this study.The results show that though the g load is an important physiological workload in flying work,the pilots' psychological workload in the high speed at lower altitude is the more important mental workload which causes the significant increase in the pilots' pulmonary ventilation and instantaneous Oxygen demand which reaches to 255 L/min.We should pay more attention to it.The results are important actually in the design and computation of Oxygen consuming quantity,carrying volume of Oxygen,and instantaneous Oxygen demand of aircraft Oxygen breathing equipment.
