Abstract
This present invention concerns an axial gas turbine engine compressor which includes a casing and a distributor wheel composed of a multiplicity of sectors in arcs of circles, with radial stator blades fixed to an external platform, characterized by the fact that the said platform is retained in the casing by two joints of the tongue and groove type, one upstream and the other downstream of the stator blades, the said downstream joint being formed between a transverse flange provided on the external platform and a flange provided on the casing, with a securing resource to create a tight joint between the two flanges. It is preferable that the securing resource should be a bolt. The invention provides for effective retention of the sector so as to prevent wear in the surfaces in contact. The solution is easy to implement.
