基于VB的民用飞机低温符合性验证模型

摘要

In general, there are two air conditioning packs in order to regulate temperature both in cockpit and cabin. If two packs both fail to work, people in cockpit and cabin will be exposed to low temperature environment, which may result in crew performance degradation and prevent the crew from successfully completing their assigned tasks-continued safe flight and landing. This article defines a low temperature certification method to validate CCAR 25.1309(a)(b)(d) regulation.%民用飞机正常情况下一般采取双套空调组件对驾驶舱和客舱进行温度调节，双套空调组件失效会导致乘员暴露于低温环境，可能会导致机组能力降低，从而影响飞行安全；基于适航条款CCAR25.1309(a)(b)(d)对民用飞机的设计要求，本文通过定义一种符合性方法，并基于VB平台开发出民用飞机低温失效的符合性计算模型，来验证对适航条款异25.1309(a)(b)和(d)的符合性，从而对民用飞机的适航验证具有指导意义。
