Aircraft Gas Turbine Science Assignment title: Gas Turbine performance
Learning Outcomes: On successful completion of this unit a learner will:
Understand the application of thermodynamic principles in the design of gas turbine modules and control systems.
- Explain the design criteria for a gas turbine intake
- Explain the design criteria for a gas turbine compressor
- Explain the design criteria for a gas turbine combustion chamber
Assignment Task/title: Gas Turbine Performance
Demonstrate an understanding of the operating characteristics of air intakes, compressors and combustors as used in aircraft gas turbines.
Part 1 - Air intakes
You are to:
- Describe the function of subsonic air intakes.
- Describe the function of a supersonic air intake.
- Explain how the formation of shock waves can influence their design and performance.
- Include and refer to examples from service.
Part 2 - Compressors
You are to:
Describe the role of the rotor and stator.
Explain the nature and cause of compressor stall and surge.
Explain how surge can be prevented by using the following methods:
- Variable inlet guide vanes
- Variable stators
- Bleed valves
- Multi-shafting
Part 3 - Combustors
You are to:
- Describe the main types of combustor used in aircraft gas turbine engines.
- Compare their operating characteristics.
- Describe the airflow pattern through a typical cannular combustor.
- Explain the function of the simplex type burner, and suggest why the duplex burner was developed.
Report - The assignment is to be:
- Written in formal report style, and include a content page, indicating the different report chapters and sections, an introduction and a conclusion
- Accompanied by a bibliography with references using the Harvard Referencing system
- A minimum of 1700 words (excluding appendices)
- Word processed in Arial font size 12
- Double spaced with titles and sub-titles
