A drag reduction arrangement for the body of an athlete moving through a fluid medium, comprises a device attachable to the athlete's body for delaying the onset of boundary layer separation at a trailing surface thereof. The device preferably comprises an array of vortex generators. As a result, form drag is reduced by an amount which is substantially greater than any increase in skin friction due to the presence of the vortices.
[ I claim:] [1.] A wearable article for use by a person moving rapidly through a fluid medium in a longitudinal direction, said longitudinal direction defining a direction of fluid flow relative to said person, and said article having a drag reduction arrangement comprising an upstream row and at least one additional row of spaced vortex generators secured to said article, at least said upstream row being located on a line at least just upstream of a surface that is curved in said longitudinal direction, each said row of vortex generators being arranged ...
