Why don't wings have dimples 2
Last night the Mythbusters put about a 2 inch layer of clay a a sedan
and drove it at 65 mph and recorded their mileage. They put dimples in the clay, like a golf ball, and repeated the same test and got 11% better mileage. This again begs the question why don't wings have dimples, especially for STOL type aircrat, where you still have laminar flow? Heck, hexagonal dimples might reflect radar better for all I know?
