大气湿度对涡扇发动机性能的影响
Influence of the atmospheric humidity on turbofan engine performance
摘要
Abstract
A humidity influence of air thermophysical properties on the turbofan engine performance model was considered to study the influence of atmospheric humidity on turbofan engine performance.The influences of atmospheric temperature and humidity on engine thrust,exhaust temperature and fu-el flow were calculated and analyzed,and the numerical humidity correction curves were compared with the experimental curves.The results show that the engine thrust,exhaust temperature and fuel flow gradually decrease as the relative humidity increases at the same atmospheric temperature and the influence of relative humidity is more significant when the atmospheric temperature is higher.The hu-midity correction coefficients of engine thrust,exhaust temperature and fuel flow linearly correlate with the humidity ratio,consistent with experimental results.But when the atmospheric temperature is below 0℃,the influence of humidity on engine performance may not be considered in practical appli-cations.关键词
