Abstract
Gas turbine engines and methods are provided that utilize particle separation features. The engines include a compressor that receives a primary gas flow, having rotors and stators configured to impinge the primary gas flow, and an impeller downstream of the rotors and the stators. A first stator includes stator extraction holes in radially outer end walls thereof. A compressor case surrounds the rotors and the stators. The engines include a bleed air system including an interstage bleed plenum. The stator extraction holes are configured to direct a portion of the primary gas flow to the interstage bleed plenum as a secondary gas flow and thereby remove particles from the primary gas flow which the bleed air system removes from the interstage bleed plenum with bleed air to expel the particles from the gas turbine engine.
