Abstract

L'invention concerne une chambre de combustion de turbomachine, configurée pour être logée dans un carter de chambre de ladite turbomachine alimenté en air, ladite chambre de combustion étant délimitée par au moins une première paroi (28, 30) d'orientation sensiblement axiale et une deuxième paroi transversale de fond (34), qui est jointive avec ladite au moins une première paroi (28, 30) et au travers de laquelle est agencé un système d'injection, caractérisée en ce que toutes les parois de ladite chambre sont perméables et comportent des orifices (54) ayant une section ne dépassant pas 0.8mm2.The invention relates to a turbomachine combustion chamber, configured to be housed in a chamber casing of said turbomachine supplied with air, said combustion chamber being delimited by at least a first wall (28, 30) of substantially axial orientation and a second transverse bottom wall (34), which is contiguous with said at least one first wall (28, 30) and through which is arranged an injection system, characterized in that all the walls of said chamber are permeable and have orifices (54) having a section not exceeding 0.8mm2.
