Spoiler or Wing?

Quote from BKL

I was doing a search for DIY spoiler/wing and came across this article that does a good job of explaining the differences between a spoiler and a wing -

This is brilliant! I've never seen an article that shows these ideas so clearly. Frankly, I didn't know the difference between the two, either, but it all makes sense.

Could we get an effective spoiler for the slingshot? I'm not sure now. The sling has nothing like the cabin shape of a sedan. I'd be interested to see some laminar flow diagrams or wind tunnel smoke tests.

If airflow has to travel longer distances it increases speed. Causing lift on airfoil surfaces. An airfoil is curved, as in an aircraft wing the airflow over the top travels a longer distance in an effort to meet the airflow beneath. As velocity above increases (travels a longer distance) pressure decreases (creating a low pressure area). High pressure will always rush to low pressure. Thus creating lift. It is what gives lift to aircraft. Changed by alerions, slats & flaps.

The variances (uplift or down) would be in the curvature (concave/convex) or lack of curvature. If you were to invert an aircraft wing it would stick to the ground.

I believe the issue with exhaust fumes in the cockpit is an issue involving the placement of the exhaust coupled with a variance of aftermarket accessories AS A TOTAL PACKAGE that can change airflow and vary depending on a multiple of aftermarket accessories, to include headwind, tailwind, and stops. I have a bullet speed top, stock exhaust with a stock low ripper windscreen and have noticed no fumes after many rides and conditions. Awaiting a NASCAR style tallboy windscreen. I really don't anticipate issues. I'll keep posted.
