AE4803: Course Overview
Catalog Description
Analysis and design of compressors, turbines and combustors for aircraft propulsion; compressor-turbine matching and off-design engine performance. Introduction to advanced propulsion architectures including scramjets, pressure gain combustion, and electric/hybrid-electric.
Course Objectives
- Familiarize students with the preliminary design and analysis of turbomachinery components (multi-stage compressors and turbines ) found in modern aircraft engines.
- Explore the concept and procedures for compressor-turbine (gas generator) matching and off-design engine performance for simple propulsion cycles.
- Introduce students to the basic analysis and preliminary design of the aerodynamics and liner cooling for main combustors found in aircraft jet engines.
- Introduce students to advanced propulsion architectures for hypersonic aircraft, and for enhanced cycle efficiency or reduced fuel-consumption in subsonic or transonic aircraft.
Learning Outcomes
A student successfully completing this course will be able to:
- Provide preliminary design parameters for compressors and turbines and characterize their performance based on a mean (pitch) line approach.
- Evaluate the operation and performance of a jet engine based on compressor and turbine maps for different operating conditions.
- Provide preliminary design parameters and define key design issues and constraints for main combustors in jet engines.
- Describe the advantages, drawbacks and challenges of various advanced propulsion architectures.
