<p>The body (1) has a round outer part (2) with a side surface (6), where the body is rotatably mounted around a rotational axis and partially overflown by a turbulent flow of a medium during rotation around the axis. A part of a surface of the outer part includes ribs (4). The ribs are regularly arranged along a circumferential direction of the body. The ribs include a curvature, and are aligned approximately concentric to the axis. The ribs include a wedge angle ranging from 20 degrees to 30 degrees. The body is partially formed from carbon fiber composite. A silicon film is applied as a mold. An independent claim is also included for a method for manufacturing a rotation body.</p> |
