1. A blade (100) for a turbomachine, having at least one impulse element housing (1.1, 1.2) with a first impact cavity (10), in which an impulse element (11) is arranged with play of movement, wherein
the impulse element housing has at least one second impact cavity (20), which is in alignment with the first impact cavity in a first matrix direction (A) and in which an impulse element (21) is arranged with play of movement, and has at least one third impact cavity (30), which is in alignment with the first impact cavity in a second matrix direction (B) crosswise to the first matrix direction and in which an impulse element (31) is arranged with play of movement; and/or at least one of the impact cavities (10, 20, 30) in at least one first and one second impact direction (A, B), which enclose between them an angle of at least 30° and at most 150° and each of which encloses an angle of at least 75° and at most 105° with a longitudinal axis (R) of the blade or vane that is perpendicular to the axis of rotation (C) of the turbomachine, in each case, has cavity walls lying opposite each other (12-14), wherein a distance between the walls (12, 13) lying opposite each other in the first impact direction (A) differs by at most 10% in comparison to a distance between the walls (14, 15) lying opposite each other in the second impact direction (B). |
