Module Overview

The module primarily considers jet propulsion and gas turbine engines. Engine types are introduced and turbojet and turbofan engines are described in some detail. Ideal and actual performance behaviours of these engines are analysed using thermodynamic and fluid dynamic theory from earlier modules. 





Although aimed primarily at Aerospace Engineering students, the module is also suitable for Mechanical Engineering students interested in Turbomachinery and/or propulsion.


Completion of the progress requirements of Level HE2.

Modules ENG2029 (Fluid Mechanics) and ENG2039 (Thermodynamics 2A).

or completion of module ENG3073 (Compressible aerodynamics)
