Patent ID: 8517666

Claim:
A turbine engine section comprising: a stationary vane stage; a rotating blade stage, said blade stage spaced from said vane stage to form an annular chamber therebetween; a manifold for delivering a pressurized fluid to the chamber; an outer diameter sealing means for restricting leakage of the pressurized fluid from said chamber; an inner diameter sealing means for restricting leakage of the pressurized fluid from said chamber, the inner diameter sealing means comprising an abradable seal material carried by a seal carrier; and a flow guide of generally forwardly open, C-shaped section extending radially between said inner diameter sealing means and said manifold, said flow guide bisecting said chamber to form a stationary chamber portion and a rotating chamber portion, the rotating chamber portion at least partially along a disk of the first blade stage, said flow guide mounted to said seal carrier and generally closing off the stationary chamber portion so that the surfaces bounding the stationary chamber portion are essentially non-rotating with the stationary chamber portion bounded by the manifold forward and outboard of the stationary chamber portion, the flow guide aft of the stationary chamber portion, and the seal carrier forward and inboard of the stationary chamber portion.
