Turbine engine compressor

摘要

In a turbine engine of the type having a centrifugal air compressor open at one end to a combustion chamber, the improvement which comprises coating the back face of the air compressor with a thermal insulating material, such as zirconium oxide. The thermal insulating material effectively insulates the relatively cool air compressor from hot leakage gases from the combustor and subsequent turbine engine components thus minimizing thermal strain on the compressor and enabling higher compressor speeds and pressure ratios and/or reduced compressor weight.
