Zusammenfassung:	PROBLEM TO BE SOLVED: To solve general problems relating to vibration of a blade of movable impellers for turbojet. SOLUTION: The impellers 10, 110 comprise the blade 12 and a support 22 of the blade 12 for extending substantially radially. The impellers 10, 110 also comprises at least one intermediate part 26 extending, in a substantially axial direction, between the blade 12 and the support 22 of the blade and at least one damping means 30 placed on at least one face 262, 264 of the intermediate part 26. The damping means is segmented in an axial and/or circumferential direction into at least two elementary damping means 36. COPYRIGHT: (C)2009,JPO&INPIT
