Abstract (en)
The cascade has blades (2, 2') arranged adjacent to each other in a peripheral direction (U). Two adjacent blades include rear edges (4) with different angles. The blades are staggered and profiled differently across an entire height or a part of the height. The blades are adjustable to different degrees. An arrangement of the blades in the peripheral direction is continued periodically multiple times. A position and angles of front edges (8) of the blades change due to a restagger across the entire height. An independent claim is also included for a turbomachine.
