摘要/Abstract

摘要： 基于航空连续供氧系统和呼吸过程，建立了吸入气、气管气各组分计算模型，并依据此模型计算分析了不同乘员供氧标准不同座舱高度所需氧流量。结果表明：所建模型适用于不同乘员类型的连续供氧流量计算，为连续供氧流量标准提供了理论依据。针对大型运输机乘员多的特点，介绍了多乘员连续供氧试验方法、试验原理，并对试验数据进行了分析。试验结果表明：在通气量为15和20 L/min的情况下，12 km及其以下高度各测试点的氧分压均达到100~83.8 mmHg，满足供氧防护生理要求。

Abstract: Based on the system for aviation continuous oxygen supply and the process of respiration, the sub-calculation models of inhalation air and trachea air were put forward to calculate the necessary oxygen flow at the different altitudes according to different criteria of oxygen supply for aircraft members. Calculation results show that the model is suitable for the calculation of continuous oxygen flows for different types of aircraft member and can provide a theoretical basis for the specification of continuous oxygen supply flow. To address the multi-member characteristic of transport aircraft, the test method for and theory of multi-member continuous oxygen supply are described and the test data are analyzed. The results show that the partial pressure of oxygen at each test point all reaches 100 to 83.8 mmHg under pulmonary ventilation 15 and 20 L/min condition when the cabin altitude is no more than 12 km, meeting the requirement of hypoxia protection.
