Abstract
Cylindrical body the outer periphery of which is provided with means to counteract vibrations occurring in that body as a result from transverse flow against it, these means comprising a number of small planes mounted according to a certain pattern and placed substantially perpendicular to the outer periphery of the body, which planes form an angle of from 5.degree. to 25.degree. with the cross-section of this cylindrical body; the surfaces of these planes at the most amounting to 2.5% of the surface of the cross-section of the cylindrical body and their lengths at most to 20% of the diameter of this body.
Claims8
A cylindrical body that at the outer periphery is provided with means for counteracting vibrations of said body resulting from a transverse flow against the outside of said body, wherein said means comprise a plurality of small planes which extend on substantially a perpendicular direction from the outer surface of said cylindrical body and which form an angle of 5.degree.-25.degree. with a cross-section of said cylindrical body which is perpendicular to the axis of said body and have a greater length than width which are mounted substantially perpendicular to the outer surface of said cylindrical body.
