Abstract
A discharge valve system of a bypass turbine engine compressor includes a flow deflector. The flow deflector has a wall provided with a plurality of ejection channels configured to discharge a discharge airflow from the compressor in a duct of the turbine engine in which an airflow circulates. The ejection channels are disposed in a plurality of concentric rows around a center and are oriented at an angle defined between a straight line normal to the wall and the axes of the ejection channels. The angle of the ejection channels vary by increasing from the peripheral edge towards the center of the wall so that the discharge airflow passing through the ejection channels is guided in a gyratory movement around the center.
