在进行涡轴发动机整机实验时,为了评定发动机在非标准大气条件下的整机性能,通常将非标准大气条件下的性能参数按照传统的换算公式换算成标准大气条件下的性能值,然后比较各状态点下的性能。按照传统的换算公式对发动机有关性能参数进行转换时,通常都是假定进入发动机的空气是干燥的。考虑到南方地区空气潮湿,特别是进入梅雨季节以后的高湿高温,当大气中含湿量达到一定值时,由于进入发动机的空气热物理性质发生了变化,
In the turbine engine experiment, in order to assess the engine under non-standard atmospheric conditions of the machine performance, usually non-standard atmospheric performance parameters in accordance with the traditional conversion formula is converted into performance under standard atmospheric conditions, and then Compare the performance under each state point. When converting the engine-related performance parameters according to the traditional conversion formula, it is generally assumed that the air entering the engine is dry. Taking into account the humid air in the south, especially after entering the high temperature and humidity of the rainy season, when the moisture content in the atmosphere reaches a certain value, due to the physical properties of the air entering the engine has changed,
