摘要： An annular combustion chamber of a turbomachine includes an inner wall, an outer wall and a bottom wall arranged between the inner and outer walls in the upstream region of the chamber, in which the bottom wall is divided into several adjacent sectors, each sector being attached to the inner and outer walls, these sectors presenting lateral edges such that the lateral edges of two adjacent sectors overlap. More precisely, each sector can include a lip extending along one of its lateral edges, this lip projecting relative to one of the faces of this sector and covering the lateral edge of the adjacent sector.

摘要： Annular combustion chamber of a turbomachine is provided. The combustion chamber includes an inner wall, an outer wall, a chamber bottom disposed between the walls in the upstream region of the chamber, and two attachment flanges disposed downstream of the chamber bottom and respectively enabling the walls to be attached to other parts of the turbomachine. Each wall is divided into several adjacent sectors and each sector is attached to the chamber bottom and to one of the attachment flanges. Advantageously, the adjacent sectors overlap at their lateral edges and there exists a degree of radial play between two adjacent sectors. In addition, the lateral edges of the sectors are inclined circumferentially relative to the principal axis of the combustion chamber.

摘要： An annular combustion chamber comprising axial walls interconnected by a chamber end wall having a coefficient of thermal expansion that is different from that of the axial walls, the chamber end wall being provided with a plurality of inner and outer fastener tabs secured by fastener systems to the end portions of the axial walls. Each fastener system comprises a bolt, a nut tightened onto one of the ends of the bolt, and a slideway bushing disposed around the bolt between the nut and the end portion of the corresponding axial wall, a determined amount of radial clearance being provided between the nut and the end portion of the axial wall so as to enable the chamber end wall to expand radially freely in operation relative to the axial walls.
