A Numerical Investigation in Effects of Inlet Temperature Distortion on Engine
Stability |
| |
| Abstract: | 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. |
