COMBUSTION CHAMBER FOUNDER DEFINING A SLOT FOR THE PASSAGE OF A COOLING AIR FILM

摘要

The chamber (102) has a chamber base (8) providing a fixing edge (8a) fixed at an annular wall (16), where the wall is fixed at a fixation edge of the chamber by bolts (20, 22). The chamber defines a slot (130), between an upstream part of the wall and an air pipe flange (128), for passing a cooling air film (132) of the wall. The air pipe flange is provided with the base and projects toward a downstream from the base. The wall has annular perforations (142) opened in the slot, where the perforations and openings (140) of supply air are arranged in staggered rows.
