Abstract

Abstract Translated from French Chambre de combustion à double paroi pourturbomach- ines comportant au moins une paroi extérieure dite paroi froide, et une paroi intérieure dite paroi chaude délimitant entre elles un espace de refroidissement.Les orifices (29) d'introduction d'air de combustion et de dilution sont du type trou-tuyère comportant un premier élément cylindrique (31) comprenant une collerette (33) évasée formant tuyère, un épaulement (34) et des portées (35-38) et un second élément cylindrique (39) et une portée tubulaire (41)Cette disposition permet les dilatations relatives des deux parois en définissant entre elles l'intervalle minimal et l'intervalle maximal. Double-walled combustion chamber for turbomachines comprising at least one outer wall called the cold wall, and an inner wall called the hot wall delimiting between them a cooling space. The orifices (29) for introducing combustion and dilution air are of the hole-nozzle type comprising a first cylindrical element (31) comprising a flared collar (33) forming a nozzle, a shoulder (34) and seats (35-38) and a second cylindrical element (39) and a tubular seat ( 41) This arrangement allows the relative expansions of the two walls by defining between them the minimum interval and the maximum interval.
