When does sectional dynamics get added to this discussion ?
How Wings Create Lift (Bernoulli's principle stands corrected.)
- Thread starter DugT
- Start date
As proved by VW Beetles (early). Over their design speed of 65 mph, air rushing underneath much faster than air over hood and roof, ergo lift. Solving this problem exampled by successive Porsche 911 designs.
It is ironic that art-deco auto design of the 1930s "looked" streamlined more than it actually was, and that the Chrysler/DeSoto Airflow had a lower COD going backwards.

The best auto example is the flying Mercedes at Le Mans 1999. One car did it, they kept going. When the second car did it they went ooops and withdrew from race.

Hers a decent explanation of where Mercedes went wrong

Amd it should be interesting…
CFD models have improved so much - I hope they can get it right. But it’s F1, so I wouldn’t bet on it lol.
I remember my Dad's models using those turbulators on the upper leading edge of the wings he built, long before I saw it on the "real" planes. Black cotton or nylon string, about .050 in diameter, held in place with AC glue. And those little winglets on the ends? Ditto.
I was so confused in class when a teacher docked me for using the term "Aspect Ratio" in an assignment I turned it. Good thing I made no reference to Reynolds Numbers - don't embarrass your teacher!
I'd like to mention, there's much more to aircraft wings than lift. If you dissect a typical, modern jet airliner, you can see that a bunch of intense measures are combined to essentially force the aircraft into the air and suspend it there. In many ways, it isn't doing what birds do at all. And that's why we should all be nervous, getting on these modern versions, IMO.

That's the stupidest thing I've ever heard. Everyone knows wings just jump into the air. Sheesh!
The effects of Hot Wings have on occasion demonstrated enough propulsion lift to elevate me from my easy chair.
As a recovering engineer, but still one at heart that has a white board on his kitchen wall and 3 kids who roll their eyes when he gets up to explain something, I momentarily forgot that this was a forum about telecasters . . .
