Guide vane stage of a turbine engine comprising a series of fixed blades connecting an inner collar to an outer collar, characterized in that said fixed blades comprise attachment platforms with flat surfaces that co-operate with a plurality of juxtaposed flat facets, the flat facets being located on the inner face of the outer collar in order to ensure attachment with a contact of a flat/flat type between the fixed blades and the outer collar.

Guide vane architecture

Use of the stator blade platforms for the deposition of a track of adjacent abradable material inside an external turbomachine shell is disclosed. The stator blades are attached to the shell so as to define an annular edge that is substantially continuous and the abradable material is deposited using this edge to delimit a boundary of the track of abradable material.
