TURBOMACHINE BLADE

摘要

A blade for a turbomachine, in particular a compressor or turbine stage of a gas turbine, having at least one matrix having a first impact chamber (10) in which at least one impulse element (11) is disposed with play, at least one second impact chamber (20) whose volumetric centroid is offset from a volumetric centroid of the first impact chamber (10) along a first matrix axis (A) and in which at least one impulse element (21) is disposed with play, and at least one third impact chamber (30) whose volumetric centroid is offset from the volumetric centroid of the first impact chamber (10) along a second matrix axis (B) transversely to the first matrix axis (A) and in which at least one impulse element (31) is disposed with play, the first matrix axis (A) and an axis of rotation (R) of the turbomachine forming an angle of at least 60° and no more than 120° is provided.

1. A blade for a turbomachine, in particular a compressor or turbine stage of a gas turbine, comprising at least one matrix having:
a first impact chamber, at least one impulse element disposed with play in the first impact chamber; at least one second impact chamber whose volumetric centroid is offset from a volumetric centroid of the first impact chamber along a first matrix axis, at least one second impulse element disposed with play in the second impact chamber, and at least one third impact chamber whose volumetric centroid is offset from the volumetric centroid of the first impact chamber along a second matrix axis transversely to the first matrix axis, at least one third impulse element disposed with play in the third impact chamber, the first matrix axis and an axis of rotation of the turbomachine forming an angle of at least 60° and no more than 120°.
