Patent ID: 7891194

Claim:
An annular combustion chamber of a turbomachine comprising: an end wall extending transversely to a longitudinal axis along which axis the chamber extends, the end wall being provided at an upstream end of the chamber; side walls extending longitudinally from the end wall to an orifice which discharges a stream of combustion gases, the orifice being provided at a downstream end of the chamber; and at least one row of openings disposed in the side walls for the intake of air for diluting a stream of combustion gases, wherein at least one dilution opening includes an upstream edge which projects in the longitudinal direction upstream to downstream toward an inside of the chamber and a downstream edge which projects in the longitudinal direction downstream to upstream toward an outside of the chamber and is asymmetric to the upstream edge with respect to a plane extending transversely to the side wall, and wherein an aperture of the opening includes an axis oriented in an oblique direction at an angle with respect to a longitudinal plane of the side wall, the axis of the aperture of the opening extends toward the inside of the chamber and toward the downstream end of the chamber.
