Aims:
* To provide knowledge of the development, performance and design of gas-turbine aeroengines. * To apply the fundamentals of fluid mechanics and thermodynamics to the performance and design of aircraft and aeroengines. * To introduce the basic mechanics of turbomachinery. Learning Outcomes: After taking this unit the student should be able to: * Understand the fundamental differences between the performance characteristics of turbojet, turbofan and turboprop engines. * Analyse thermodynamic cycles for turboprop, turboshaft, turbojet and turbofan engines. * Understand principles and performance of compressor, turbine, combustor, intake and exhaust nozzle. * Calculate performance of engines at design and off-design conditions. Understand basic turbomachinery design. Skills: Problem solving; numeracy; working independently. Content: Birth of jet engine; engine classification; operational envelope; thrusts and efficiencies; thermodynamic cycles (turboshaft, turbojet, turbofan); combustors; intakes (subsonic and supersonic), afterburners and nozzles; design and off-design performance; turbine cooling. Topics for self study that could be examined. |
