FIELD: machine building.
SUBSTANCE: present invention relates to an outer housing of a composite material for an axial compressor of a turbine machine; at the same time, the housing usually contains a round wall with the matrix and fibrous stiffener. The housing (28) contains a round wall (32) with the inner surface (40), which has a continuous curvature on the circumference of the wall (32). The wall contains flat edges (42), which are made level with the inner surface of the curved wall. The edges (42) are arranged in circular rows to let the annular rows of stator blades be placed on them. The edges (42) are made as flat discs to support the blades for optimizing the position of the blades and, at the same time, to reduce the stress concentration in the areas of platform/wall cooperation.
EFFECT: invention makes it possible to reduce the stress concentration between the wall of the housing and the blade platform, increases the accuracy of the blade's orientation, facilitates the regulation of the chord of the blades' orientation or blades' angle.
