HIGH PRESSURE AIR SUPPLY DEVICE WITH TURBINE MACHINE TURBINE ROTOR BLADES AND METHOD FOR REDUCING PRESSURE LOSS IN THE INTERIOR CHANNEL OF THE COMBUSTION CHAMBER OF A TURBOMACHINE.

摘要

P INTERIOR CHANNEL IN A COMBUSTION CHAMBER HAVING OPENINGS PRIOR TO SUCTION. BR/ A device for supplying a high-pressure air stream (92) to the turbine rotor blades (112) of a turbomachine comprises a plurality of circumferentially spaced front withdrawal openings (96). others, which are formed in the inner casing or inner wall (74) of the inner channel (72) of the combustion chamber (88), these openings to reduce the separation of the air flow through the inner channel and thus to reduce turbulence and pressure losses in the channel. BR/ Application to gas turbine engines. / P
