I found a great video by an aerodynamicist today. Through my CFD work, I've come to realise it's all about pressure. This video clarifies some points, but doesn't explicitly say that aerodynamics is about MOMENTUM and the pressures it creates.

Video: How aeroplanes' wings really work - Telegraph

I get annoyed when laymen say that cars today are designed "backwards". When you don't have twenty feet to recover pressure, you need to make gains on the front end. I suggest that the aero template induces lift and hence drag, and maybe it should be more elliptical on the front - like a shark.

Aeromodeller2

The Aeromodeller II favors a triangular cross-section similar to the ME-262, which some consider 'sharklike'.


It's also intended to be articulated, so it can 'swim' through gusting air.

Colani Wing Car

I think Colani assigned Cd 0.20 the the 'Corvette' Wing Car.

I'd sure like to see one float by.
PS 'like the foo-fighter ganglia!

Do you know about the Aeromodeller story?

It's one individual artists effort. He's in no hurry. The hull cross-section was designed upside down in liquids with the heavier liquid in the 'bag' representing lift. The same way Gaudi engineered his cathedral.

Long as a football field with a cabin the size of a studio apartment, made with mountaineering tent technology. When it runs low on hydrogen fuel you just drop anchor and the rotors become windmills that crack water for the hydrogen. So you sample the local produce for a few days and then proceed on your way around the world!
