On: American Airlines agrees to purchase Boom Supersonic Overture aircraft

[samstave]

I am convinced that if you were to dimple the propeller (tips) such as a golf ball is pitted, you would reduce this effect.

Further, if you wer to dimple/convex in an alternating pattern the leading edge of any aero ... efficiencies would increase.

Micro-dimples are better.

Understand the eddys, as Da vinci would say....
