Abstract

The main objective of this study is to analyze the performance parameters and simulation of PW615F turbofan engines both with and without secondary combustion chamber. For validation a commercial software called GasTurb & GSP is used. The purpose of the the propulsion system plays an important role in determining of mission and flight regime of an aircraft In this study, the first choice and then simulate a turbine engine thrust which is equivalent to 6.35 KN produce. And more the method for analyzing on-design and off-design analysis of twin-spool unmixed flow turbofan engines and also we present scaling method to produce the characteristics performance maps of compressor and fans. Mathematical modeling of engine performance has been conducted by serial nested loops algorithm. Performance of components have been modeled by performance diagrams, thermodynamics and gas dynamic equations. Mathematical modeling of a turbofan engine is somewhat complex. Therefore, initially, the off-design performance of a twin spool power generating gas generator and twin spool turbofan are analyzed. Finally, the off-design performance of a twin spool unmixed flow turbofan engine is simulated and the generated performance diagrams have been analyzed. The results show that the cycles that Advantage the secondary combustion chamber dramatically increase the specific thrust, reduce the main secondary combustion chamber outlet emissions and increase the output power of the low pressure turbine..
