摘要
发动机进口温度畸变是影响发动机稳定性的关键因素之一。进口温度畸变对某新型涡轮风扇发动机稳定性和性能的影响进行了数值研究,得到了该发动机的温升率阈值和温升阈值。分析了畸变在发动机流道中的发展情况,同时给出了温度畸变对发动机主要性能参数推力和耗油率的影响。
Inlet temperature distortion is one of the key factors effecting engine stability. A numerical investigation has been finished in effects of inlet temperature distortion on stability and performance of a modem turbofan engine. Both temperature rise rate threshold value and temperature rise threshold value has been obtained. The development of distortion in engine flow path is introduced in this paper together with the effects of temperature distortion on main performance parameters: thrust and fuel consumption.
