Precision Casting for Gas Turbine Engines

Abstract

Fierce competition in the aero‐engine market has led to the need for the engines that are more powerful, more compact and more fuel‐efficient. This has meant that more and more performance must be extracted from engine components, many of which have to operate at increasingly higher temperatures. An example is the high pressure turbine blade of the RB 211 engine. Only five inches long, it extracts 500 hp from the gas stream in which it operates and is exposed to gas temperatures in which it would melt but for its complex internal and surface cooling systems.
