AIR INTAKE BALL FOR A TURBOMACHINE INJECTION SYSTEM COMPRISING AN AERODYNAMIC DEFLECTOR AT ITS INPUT

摘要

An air intake spin (100, 200) for an injection system (70) of a turbomachine comprises an upstream wall (102, 202) and a downstream wall (104, 204), both of revolution around a axis (44) of the air intake spin, and the fins (106, 206) distributed around the axis (44) and connecting the upstream wall to the downstream wall so as to delimit between the upstream and downstream walls air inlet channels (108, 208) each having an inlet (110, 210) and an outlet (112, 212). The spin includes an aerodynamic deflector (120, 220) extending the downstream wall (104, 204) radially outward and having a concavity turned upstream. The aerodynamic deflector extends radially opposite the respective inlets (110, 210) of the air inlet channels and thus makes it possible to limit the pressure drop of the air supplying the air inlet channels (108, 208).
