Unit of study_
AERO3261: Propulsion
This unit of study teaches the students the techniques used to propel aircraft. The students will learn to analyse various propulsion systems in use- propellers, gas turbines, etc. The topics covered include: Propulsion unit requirements for subsonic and supersonic flight; thrust components, efficiencies, additive drag of intakes; piston engine components and operation; propeller theory; operation, components and cycle analysis of gas turbine engines; turbojets; turbofans; turboprops; ramjets. Components: compressor, fan, burner, turbine, nozzle. Efficiency of components: Off-design considerations. Future directions: minimisation of noise and pollution; scram-jets; hybrid engines.
