Students are expected to have basic knowledge of aerospace propulsion systems and turbomachinery.

The main objective of the course is to develop the ability to design and calculate the performance of air-breathing engines and their components. The students are expected to be able to: - Understand the processes of heat and mass transfer applied to the aerospace propulsion systems - Analyze the performances of the aerospace propulsion systems. - Select and design the most suitable powerplant for an aerospace vehicle according to its mission, including the design of the subsystems composing the engine. - Test the correct operation of the turbomachinery as part of an aerospace propulsion system.
