Title (EN) COMBUSTION CHAMBER FOR A TURBINE ENGINE HAVING IMPROVED AIR INLETS
(FR) CHAMBRE DE COMBUSTION DE TURBOMACHINE COMPRENANT DES ORIFICES D'ENTREE D'AIR AMELIORES
Abstract: front page image
(EN)The invention relates to a combustion chamber (10) for a turbine engine, including two coaxial walls comprising a plurality of air inlets, each of which is configured such that the orthogonal projection (44p) thereof in a plane through which the axis (28) of the injection system (20) that is closest to said inlet passes and that is perpendicular to an axial plane (B-B) through which said axis (28) and the combustion chamber axis pass, has a convex-shaped upstream edge (58) when viewed from downstream.
(FR)Chambre de combustion (10) de turbomachine, comprenant deux parois coaxiales comportant une pluralité d'orifices d'entrée d'air, dont chacun est configuré de sorte que sa projection orthogonale (44p) sur un plan passant par l'axe (28) du système d'injection(20) le plus proche dudit orifice et perpendiculaire à un plan axial (B-B) passant par cet axe (28) et par l'axe de la chambre de combustion, présente un bord amont(58)de forme convexe lorsqu'il est vu depuis l'aval.
