Abstract:
Internal hot corrosion which occurs in hollow uncooled gas turbine engine components is reduced by increasing the oxygen potential of the gas which fills the hollow portion of the component. In particular, blades and vanes which operate in conditions where there is a pressure differential across the component have deliberate venting holes introduced in a sealing structure at one end of the component to permit gas flow through the hollow portion of the component.
