Abstract
The present application relates to an annular outer housing of a low-pressure compressor of an axial turbomachine. The housing includes an annular wall of a composite material with an organic matrix. The housing includes an annular array of blades extending radially, the blades including platforms fixed to the annular wall. The housing also includes a radial annular flange having means of mounting configured to allow fitting of the housing in the turbomachine. The annular flange is attached to the annular wall and bounds an annular insertion area for the platforms of the blades. The annular flange is fixed on the annular wall by means of clamping. The present application reduces the manufacturing cost of the housing and supports the transmission of force between the annular flange and the blade platforms, which has the advantage of reducing stresses in the annular wall.
