| description | A flow deflector (4) of a discharge valve system (1) of a bypass turbine engine compressor, the flow deflector comprising a wall (5) provided with a plurality of ejection channels (6) able to discharge a discharge airflow (Fc) from the compressor in a duct (V1, V2) of the turbine engine (100) in which an airflow (F) circulates, wherein the ejection channels are disposed in a plurality of concentric rows around a centre (A) and are oriented at an angle (α) defined between a straight line (D) normal to the wall and the axes (C) of the ejection channels, and varying by increasing from the peripheral edge (15) towards the centre of the wall so that the discharge airflow passing through the ejection channels is guided in a gyratory movement around the centre, and in that at least one row of channels arranged in the vicinity of the peripheral edge is designed so that the discharge flow does not burn the wall of the duct. |
