摘要: A device for use with surfaces submerged in and moving in relation to a gas or liquid to eliminate surface flutter. Such flutter is caused by turbulence in the form of eddies formed in the gas or liquid. The device reduces the size of the eddies by placing a wall within a predetermined distance of the surface. The wall has a structure of bumps or openings formed thereon. The size of the bumps or openings, the spacing thereof along the wall, and the distance of the wall from the surface are related, so that the maximum eddy size is determined by the distance of the wall from the surface.

摘要: A magnetic bearing for contactless support of a rotor in relation to a stator, with at least one bearing gap between rotor and stator, in which magnetic zones of rotor and stator, appropriately designated rotor magnet and stator magnet, respectively, are disposed facing each other a short distance apart. The stator magnet is fixed to the stator in such a way that it can vibrate freely in substantially one plane, which is aligned parallel to the magnet faces of the rotor and stator magnets facing each other in the bearing gap. In this arrangement, a mechanical friction device is disposed between the stator and stator magnet to damp the vibrational movement of the stator magnet.
