Combustion chamber comprising a wall comprising a cooling duct between a first partition and a second partition

摘要

The invention relates to an annular combustion chamber for a turbomachine. The combustion chamber includes an inner wall and an outer wall (25). A first wall of the inner wall and the outer wall (25) includes a first partition (40) and a second partition (42). The second partition (42) is radially spaced from the first partition (40) to form with the first partition (40) a cooling duct (41) of the first wall. The cooling duct (41) includes an inlet wall (46) and an outlet wall (48) which extend between the first partition (40) and the second partition (42). At least one of the inlet wall (46) and of the outlet wall (48) is crossed by at least one cooling orifice (85, 86) having an axial component along the longitudinal axis of the chamber. combustion.
