Most pec...bizarre aerodynamics thread.

Are there any regulations that would prevent a Delta Wing type design from appearing at F1? The underbody aerodynamics alone would be a deal-killer at first glance.

Are there any regulations that would prevent a Delta Wing type design from appearing at F1?

There are many.

Covered wheels are not allowed
Front wheels that narrow are not allowed
The extreme rear weight bias is not allowed
It also violates several bodywork rules, including but not limited to:
3.7.1

Aside from that, there are more practical limitations, such as:
-it would be difficult to get adequate cooling for the 2014 powertrains within the tiny body of a deltawing-like design, which originally housed an engine with much lower heat rejection requirements. They had quite some difficulty getting it to not overheat the 1.9l elan engine.
-not having wings makes it hard to adjust aerodynamic balance and change drag/downforce betweeen tracks
-Pirelli doesn't supply a bicycle tire for the fronts
-You'd be giving up DRS
-You can't capitalize on the weight advantage of the design because of the minimum weight

Found this on the web, obviously a Tyrrell 011 (1981-83), anyone who knows more about it, a primitive diffuser perhaps?

1983, the first year with the flat bottom rule, picture dated Januari 13th, the above might be the very first diffuser?

But check this out, back in 1974 they knew how to make a decent scoop!

Some motorcycle aero:

Just out of curiosity, do wings that generate downforce make any sense on motorcycles?

I'd say they don't make any sense when the leaning angle is more than 45°. Because when the angle is more than 45° the downforce will push the motorcycle off the track rather than pressing it on the track.

It doesn't make sense for providing grip in corners unless the wings are active and stay perpendicular to ground.

Wings need not be perpendicular to the road.

Wings need not be perpendicular to the road.

Perhaps the wings should be applied radially to counter centripetal forces, F = m * v^2/r, in the corners?
