This project deals with the understanding of the secondary air system of a three spool turbofan. The main purpose is the creation of secondary air system and thermal models to evaluate the behavior of this kind of engine architecture and estimate the pros and cons in comparison with a typical two spool turbofan.
A finite element model of the secondary air system of the engine has been designed based on the experience of typical jet engines manufactured by Snecma. The inner thermodynamic pattern and mass flow rates of the engine were obtained.Some local improvements were then made by making analogies with the engines manufactured by Snecma. After having communicated the results to the performance unit to get updates thermodynamic cycles, a quite reliable model was obtained.
