Anotation:
This course gives basic knowledge of the aircraft propulsion theory, thermal cycles of aircraft powerplants and basics of aero- and thermodynamics of aircraft powerplants components. The influence of design parameters on propulsion system efficiency, specific fuel consumption and thrust is analyzed for the given flight velocity. Design layouts of the aerospace propulsion units are introduced and function of their components is described. The focus is given on the comparison of various systems and the choose of the appropriate one. Enviromental aspects are mentioned together with the common and alternative fuels and energy sources.
