Combustor and Turbine Blade Properties
· High combustion temperatures improve the specific fuel
consumption and the specific thrust of the engine.
· The combustor and turbine blades are the high temperature
components of the engine. They must have high melting points and be
resistance to thermal fluctuations.
and oxidation resistance are needed to increase the time
dimensional stability is important and should be maintained under temperature
fluctuations or the rotation induced tensile stresses.
