Desired 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.
· Corrosion and oxidation resistance are needed to increase the time between overhauls.
· Component dimensional stability is important and should be maintained under temperature fluctuations or the rotation induced tensile stresses.
