Wind Tunnel Killer?

Accounting for the changes in gravitational resistance as a rider rounds each bend is one of the complex calculations happening in the background. Velodrome corners are banked dramatically so riding into, around and out of each turn influences the rider’s gravitational resistance. Not only does the rider climb a slight incline, but he leans dramatically, changing the vertical distance climbed by the center of mass of the bike and rider. Tires also spin faster than the rider’s center of mass moves because of the characteristic lean. Froncioni and Alphamantis engineers derived a correction for this factor called Virtual Elevation based on velodrome geometry and rider speed. As the rider rounds the track, this equation estimates the elevation gained and lost by the rider’s center of gravity as he leans through a bend. Although he wouldn’t describe the equation in detail, it i...

Very interesting article for aero-heads but the term gravitational resistance might be somewhat offputting to some! [link]

Is the Track Aero System the new ultimate in aero testing? Will it make wind tunnel testing obsolete? [link]
