Abstract

In aeroengine design, predicting the effects of design parameters on total engine performance is extremely difficult, as all engine components are interrelated. Therefore, engine design tools are needed which provide the designer with more insight on the design process. This thesis focusses on the design of the fan and booster stages of a high-bypass-ratio twin-spool turbofan engine in the conceptual design phase, and consists of three modules: an aerothermodynamics, weight estimation and noise prediction module. After validation using existing engine data, the effects of increasing fan tip diameter, spool speed and bypass ratio on the engine weight, aerodynamic performance and noise production are tested.
