An upright rider in the aero position has about the same frontal area as a recumbent according to the chart in Scientific American (p. 150 Dec. 1983). A fairing in the shape of a 4:1 body of rotation with a 25% kamm cut could be very competitative with a lower weight. |
The pics look cool!
I remember that SA article. I know two of the authors, Kyle and Malewicki. They came to our ASME conference in 1985 and both tried out the bike with fairing in my sig photo.
I think you probably will approximate the drag of a recumbent with that design.
Our bike with fairing matched the CdA of a rider drafting another bike almost exactly-CdA reduced 50%.
I wrote about an 80 page paper on that fairing and the testing. I scanned it the other day. Of you want a PDF, email
steve@stevebruhn.com and I will send you one.
