BLADE DISC HAVING A CIRCULAR GROOVE FOR RECEIVING BLADE BASES

摘要

According to the invention, a circular row of blades (18) is retained in the grove of a disc (15) after insertion through an axial opening that is finally blocked by a key bearing an additional blade (14). Said assembly makes it possible to provide a large number of blades on the disc (15) by suppressing the need for locking parts that separate the blades and are screwed into the groove.
