    摘要:

    对民用航空器座舱高低温环境适航符合性开展分析。首先对座舱高低温环境适用的适航条款FAR/CCAR 25.831(g)和FAR/CCAR 25.1309(a)(b)(d)进行解读和分析;进一步得出基于人体核心温度的舱内可接受的高低温环境标准;随后,提出针对座舱高低温环境的适航符合性思路,包括:开展失效状态下座舱高低温环境预测,并以此为输入开展人体核心温度数值模拟计算,然后开展高低温环境下人体生理试验以验证人体核心温度模型数值模拟的准确性,最终依据外界环境温度人体核心温度生理指标安全性指标的等效安全准则来说明对适航条款FAR/CCAR 25.831(g)和FAR/CCAR 25.1309(a)(b)(d)的符合性。

    Abstract:

    This paper analyzes the airworthiness compliance of civil aircraft cabin in high or low temperature environment. Firstly, the airworthiness requirement of FAR/CCAR 25.831(g) and FAR/CCAR 25.1309 (a)(b)(d)clause applicable to high or low temperature environment in cabin were interpreted and analyzed. Furthermore, the acceptable standards of high or low temperature environment based on the core temperature of human body were obtained. Then, the idea of airworthiness compliance for high and low temperature environment of cockpit was put forward including: predicting the high or low temperature environment in cabin under failure conditions, and with this as the input, the core temperature of human body was simulated by simulation calculation, which can predict the core temperature of human body and evaluate the health of human body. Then the laboratory test for measuring the core temperature of the human body under the high or low temperature environment was carried out to verify the accuracy of numerical simulation of human core temperature model. Finally, the compliance of airworthiness clause FAR/CCAR 25.831(g) and FAR/CCAR 25.1309 (a)(b)(d) to airworthiness provisions was explained according to the equivalent security rules of external environment temperature human core temperature physiological index safety index.
