The purpose of the pneumatic system is to supply compressed air for a controlled temperature and pressure environment during all phases of flight and ground operation.
增压系统的作用是为飞行及地面所有阶段的温度和压力控制提供压缩空气。

The reason that supplyair is not uniform for traditional air conditioning system of passenger car are analyzed, the design methods of static pressuresupplyair duct are given.
Hence, for improving the uniformityof airsupply and the performance of the duct, it is of great importance to studythe rules of resistance distribution in static pressureairsupply duct.
