MAE4980 - Aircraft engines

Leader(s): D R Honnery

Offered

Clayton First semester 2009 (Day)

Synopsis

This unit deals with the operation, performance and design of spark ignition and gas turbine aircraft engines. Initially the engines will be treated as thermodynamic systems. A more detailed investigation of engine individual components will follow. Component integration will be examined through investigations into operation, performance and design. Methods based on thermodynamic modeling to predict engine performance will be investigated, including for gas turbines design and off-design conditions. Students will be required to undertake a significant individual project dealing with aspects of each engine.

Objectives

The unit has as its primary objective:

1. To understand and become familiar with the design, operation, performance and thermodynamic modeling of aircraft engines.This objective will be achieved through a student being able to:
2. Develop the basic thermodynamic relations for ideal and real SI and GT cycles.
3. Demonstrate familiarity with engine components and their operation.
4. Understand the thermodynamic and fluid mechanic relationship between the individual components that make up each engine.
5. Demonstrate an understanding of objective 4 above by being able to undertake the necessary design calculations for these components.
6. Demonstrate an understanding of the relationship between engine operation and its performance for particular aircraft.
7. Integrate objectives 2 and 4 through the development of thermodynamic models to predict engine performance for a typical flight envelope.Students are further encouraged to develop:
8. An appreciation of how component integration within complex thermodynamic systems is used to produce a particular type of operation and level of performance.
