Course Description:
Module Code - Title: ME4528 - PROPULSION SYSTEMS Year Last Offered: 2017/8 Hours Per Week: Grading Type: N Prerequisite Modules: Rationale and Purpose of the Module: To provide students with fundamental knowledge about aircraft propulsion systems, particularly the air-breathing jet engine. Students should attain understanding of the thermodynamics and mechanics of the engine as a whole as well as individual components. Syllabus: An overview of propulsion systems and the development of thrust. A review of the conservation equations of fluid mechanics. The thrust equation. Propulsion efficiencies and implications for system design. A review of compressible fluid flow covering isentropic flow through ducts, constant area heat transfer and shock wave formation. The thermodynamic design of air-breathing engines covering the ramjet, the turbojet, the turbofan and the turboprop. Typical engine performance and aircraft matching. Detailed aerothermodynamic design of intakes, combustion chambers and exhaust nozzles. Detailed internal design of compressors and turbines covering twodimensional blade row velocity diagrams, boundary layer flow and performance limitations. Learning Outcomes: Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis) On successful completion of this module the student will be able to: 1. describe the physical mechanisms which result in the production of thrust; 2. identify the key mechanical components which comprise various air-breathing propulsion systems; 3. undertake an aero-thermodynamic analysis of various air-breathing propulsion systems which will result in the prediction of thrust produced; 4. describe the aero-thermodynamic operation of both axial compressors, turbines and exhaust nozzles; 5. design the basic rotor and stator blade shapes and calculate the number of stages required to give an axial compressor a certain pressure ratio; and 6. design the basic blade shapes and calculate the number of stages required to give an axial turbine a certain power output.
