UCK 421 - Jet Propulsion

Course Objectives

?Understand how thrust is generated with jet engines;
?Calculate the ideal performance of the complete engine and the engine components under different design conditions,
?Calculate performance under off-design conditions,
?Understand how much the performances change under actual conditions with component losses,
?Gain the ability to apply all of this knowledge to design procedures.
