Transient Analysis of Volume Packing Effects on Turbofan Engine

An integrated turbofan model, capable of coupling engine performance prediction with air-system calculation, is established. Efforts are focused on predicting volume packing effects on turbofan engine both in acceleration and in deceleration process. Results show that the volumes in secondary air-system exert more impacts on transient loads, compared with those in main gas path. Due to disk cavities in air-system, the percentages of coolant flow for the turbines are significantly reduced in acceleration manoeuvre, which result in potential adverse transient thermal load on the engine.
