Abstract:
1. An apparatus comprising: a gas turbine engine including a rotatable shaft coupling a compressor and turbine and having a working fluid flow path through the compressor, a combustor, and the turbine; and a fluid flow path structured to pass a fluid and disposed between the shaft and a radially inner surface of the working fluid flow path, the fluid flow path including a flow directing member that is stationary relative to the rotatable shaft, the flow directing member retained within the gas turbine engine via a coupling that includes a protruding member at an end such that the protruding member is slidably retained in a component of the gas turbine engine to permit radially free motion relative to the working fluid flow path during operation of the gas turbine engine; wherein the flow directing member is in contact with a portion of the gas turbine engine at another end, the contact permitting axially free and radially free movement of the flow directing member.
