Study on thermodynamic cycle parameter matching for intercooled recuperated aero-engine

The intercooled and recuperated processes were incorporated into the conventional high bypass turbofan engine thermodynamic cycle. Consequently, the intercooled recuperated aero-engine (IRA) simulation model was built and an overall performance simulation program was developed. Then, analysis on choosing and matching the thermodynamic cycle parameters of IRA was conducted. The result indicates that there are some thermodynamic cycle parameters such as intercooler effectiveness, recuperator effectiveness, bypass intercooling split, pressure ratio assignment between booster and high pressure compressor, overall pressure ratio and bypass ratio, which have significant influence on IRA performance. The turbofan engine performance can be improved with the proper use of intercooling, recuperation and the optimized matching of the thermodynamic cycle parameters.
