ABSTRACT:
Several embodiments of aerodynamic devices for improving the drag coefficient and reducing the wind resistance of a body moving through the air such as a motorcycle and/or a helmet worn by a rider of the motorcycle. The aerodynamic devices comprise a plenum chamber to which air is delivered through a relatively small ram air inlet opening. Air is discharged from the plenum chamber through a plurality of small apertures for generating a thin turbulent boundary layer between the body surface and the air flowing across the surface to promote laminar flow across the body surface.
