COMPRESSOR ENDWALL BLEED SYSTEM

摘要

A compression system endwall bleed system having a plurality of bleed slots (41) formed in a mechanical housing (38) downstream of a rotating shrouded rotor (35). In one embodiment, the plurality of bleed slots (41) bleed off a separated tip boundary layer to relieve back pressure associated with this blockage. A sealing structure (47, 48) downstream of the shrouded rotor (35) is utilized to minimize working fluid leakage ahead of the plurality of bleed slots (41).
