SESA2023 Propulsion

Module Overview

This module introduces the fundamental principles of aircraft propulsion, and covers air-breathing and rocket propulsion systems. The module focuses on the analysis and determination of thrust and performance criteria for propulsion systems such as ramjets, turbo-jets, turbo-fans and rockets. Three laboratory sessions complement the taught material.

Aims and Objectives

Module Aims

• To provide a first course in aerospace propulsion, familirising students with basic principles. • To introduce the major classes of aerospace propulsion systems, and to develop consistent methods of overall performance evaluation. • To emphasise the practical application of theoretical analysis and encourage a deeper appreciation of propulsion systems design and manufacturing • To familiarise students with the major suppliers of aerospace propulsion systems and their industrial roles.
