Configuration of dilution openings in a turbomachine combustion chamber wall

摘要

An annular combustion chamber of a turbomachine is provided. The combustion chamber includes an end wall provided at an upstream end of the chamber and side walls extending longitudinally from the end wall to an orifice for discharging a stream of combustion gases provided at a downstream end of the chamber. The side walls includes at least one row of openings for the intake of air for diluting the stream of combustion gases. At least one dilution opening has an upstream edge which projects toward the inside of the chamber and a downstream edge which projects toward the outside of the chamber and is asymmetric to the upstream edge with respect to a plane extending transversely to the wall. An aperture of the opening having an axis oriented in an oblique direction with respect to the wall. This direction being oriented toward the inside and toward the downstream end of the chamber.
