Remarks (specific information about assesment, entry requirements, etc.):
Goals:
This course is designed to provide the students with a basic knowledge of the energy conversion proces in the gas turbine engines for shaft and thrustpower, the combustion proces in the gas turbine and the construction.
Computer use:
Laboratory project(s):
Demonstration of a small two-shaft gas turbine: start-up and running, instrumentation and analysis of measured data. Demonstration of the aerodynamic performance of a small three-stage axial compressor. Duration 3-4 hours. No report required.
Design content:
The course has a design aspect in so far as the choice of the thermodynamic cycle is included in the definition of "design". Some aerodynamic design aspects are dealt with, the treatment of the pure mechanical design restricted to a short description of some existing engines.
Percentage of design: 25%
