Skyway 8-Inch Wheels: What A Drag
One of the four launchers we've prototyped includes the 8-inch Skyway wheels from the KOP. They worked pretty well, but the notable thing is that at high RPMs the wide plastic spokes move a LOT of air. The drag from the spokes is dramatic. We are now looking into covering the spokes with a lightweight layer of something (I suggested either mylar or duct tape) to keep them from acting like cooling fans. One mentor's primitive guesstimation is that the aerodynamic drag might be costing us a 10% loss in RPM.
Just something else to think about... |
