Abstract: | Rain ingestion in aero engine could cause compressor surge, combustor blow-out, mechanical damage and occasionally significant thrust lost. The paper analyses the effect of rain ingestion on the engine performance and describes a generalized model to estimate the mechanical, aerodynamic and thermal impact on the engine.These estimates are then used to evaluate the rain ingestion capability of a turbofan engine. |
