Abstract
The invention relates to a rotation-locking device of a sector of rectifier blades () mounted in a sector of the turbojet housing. A sector of blades comprises a support base (). A housing sector comprises two recesses perpendicular to the axis of the housing, each receiving an edge (--) of the support base. At one and the same axial end of the housing sector, each recess opens out into a seat (--) defining an axial face (-). The device comprises an axial stop () adapting itself on each side in the seats (--) of the two recesses, and once the complementary sector of the housing is installed and during operation of the turbojet, bearing on the axial faces (-) under the thrust of the complementary sector of rectifier blades in order to provide rotation locking.
