Default Re: Unexpected response from 3M about VHB 4950 tape for rigid solar panels

Math happened:

... you've got LOTS of relatively little(??) force involved.
Cranking through lift and drag calculations for a flat plate (and ignoring the fact the Sprinter is under the panel) shows only 30 pounds of upward force (lift) for a 5 degree angle of attack at 60 mph on your panel. The drag force is only about 18 ounces.

--dick (quite surprised by the result)
p.s. the Sprinter under the panel increases the lift ... quite like flying in "ground effect"
