Abstract
A compression system endwall bleed system having a plurality of bleed slots formed in a mechanical housing downstream of a rotating shrouded rotor. In one embodiment, the plurality of bleed slots bleed off a separated tip boundary layer to relieve back pressure associated with this blockage. A sealing structure downstream of the shrouded rotor is utilized to minimize working fluid leakage ahead of the plurality of bleed slots.
