Abstract: An apparatus for delivering high pressure cooling air to the turbine rotor blades of a turbo machine comprises a plurality of circumferentially spaced, forward bleed openings formed in the combustor inner casing or inner wall of the combustor inner passage of the turbo machine which are effective to reduce separation of the air flow directed through the combustor inner passage and thus reduce turbulence and pressure losses therein.
