This course aims to enable you to:
- gain a deeper appreciation of gas turbine operation and to make high-level predictions of gas turbine behavior in various flight scenarios. This will be achieved by comparing analytical and numerical predictions of turbine behaviour with physical observations made in a laboratory setting.
- develop a strong understanding of rocket engines for different mission profiles. This will include reaching Earth orbits from sea-level (chemical rockets) and for satellite station keeping & interplanetary missions (ion-thrusters).
- develop a deeper understanding of the thermodynamic aspects of reciprocating piston internal combustion engines and the role that energy harvesting of exhaust gases can have on aircraft fuel consumption in an era of greater powertrain hybridization.
