Abstract

A turbomachine stator vane set includes a ring of vanes having platforms arranged in a housing formed on an outer shell. The bottom of the housing has a non-planar surface which is spherical or cylindrical with a radius of curvature R, and the cooperating surface of the platforms has a corresponding non-planar surface which is spherical or cylindrical with a larger radius of curvature R+.DELTA.R prior to fitting and which is reduced to the radius R under stress, by the action of fastening rivets used to assemble the vane platforms with the outer shell.
