Patent ID: 7059832

Claim:
Rotation-locking device for at least one sector of rectifier blades mounted in a sector of the housing of a turbojet, each sector of rectifier blades comprising a base for supporting the blades, the sector of the housing comprising at least two recesses which extend in planes perpendicular to the axis of rotation of the turbojet housing and each of which receives an edge of the base of the sector of rectifier blades, characterised in that at one and the same end of the sector of the housing, in an axial plane, at least two recesses each comprise a seat defining, with the corresponding recess, an axial face of dimensions larger than the dimensions of the recess cross-section, and in that the rotation-locking device comprises a stop positioned so as to extend axially, adapting itself on one side in the seat of one of the recesses and on the other side in the seat of the other recess and, after installation of the complementary housing sector and during operation of the turbojet, coming into contact with the axial face of each seat under the thrust of at least one complementary sector of rectifier blades in order to lock in rotation at least one sector of blades, the stop being either rigidly connected to the sector of blades or being a bar comprising at least one end with a longitudinal slot for resilient mounting and holding in the seats.
