Transient analysis of volume packing effects on turbofan engine

摘要：

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 airsystem, 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.
