Re: Rotation Drag

["John Burk" <joyseydevil@comcast.net>]

I came across what I quoted about the minor effect that rotation has on the
drag of an open wheel at this review of the book "Aerodynamics of road
vehicles"

www.wisil.recumbents.com/wisil/demma/aero_review.htm - When you think of the
tops of Joe Laws and Fast Freddies tires going through the air at nearly the
speed of sound I would think that might add greatly to the wheels drag -
May-be it's the fact that the bottom of the tire has no foreward speed- Saw at
a place I've forgotten that the Cd for the frontal area of a tire is .58 .
