ANNULAR DEFLECTION WALL FOR A TURBOMACHINE COMBUSTION CHAMBER INJECTION SYSTEM PROVIDING A WIDE FUEL ATOMIZATION ZONE

摘要

A deflection wall known as venturi is disclosed to improve the air fuel mix within an injection system installed in a turbomachine combustion chamber, having a downstream edge formed by the repetition of a pattern extending on each side of a virtual circle and formed from a plurality of bosses each of which is centred relative to a corresponding plane inclined by an angle α from a corresponding median axial plane of the annular deflection wall passing through a corresponding end of the downstream edge of the annular deflection wall at the boss considered.
