Abstract

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.
