SHOCK ABSORBER FOR VIBRATIONS BETWEEN ENDS OF ADJACENT COMPOSITE MATERIAL VANES OF A MOVABLE WHEEL OF A TURBINE ENGINE, AND RELATED MOVABLE WHEEL ELEMENT, MOVABLE WHEEL, AND TURBINE ENGINE

摘要

The invention relates to a shock absorber for vibrations between ends (24) of adjacent composite material vanes (14) of a movable wheel of a turbine engine, said shock absorber including a blade (102) that is to be inserted, in the direction of the length thereof, into tangential cavities (34) that are provided opposite each other within the ends of two adjacent composite material vanes of a movable wheel of a turbine engine, said blade being provided with a plate (304) that extends transversally relative to the blade and is intended to come into contact with the adjacent side edges (24c) of the ends of the vanes when the blade is inserted into the cavities of said ends.
