is it the curve of concave?

so, is it the curve of a concave that makes if do its low pressure thing? why not use flat panels, like a v - not vee, the opposite. would that have the same effect?

hey native,

not quite sure about the pressure thing, but i think the shape of the concave makes a diff…for a single con, a steeper parabolic slope near the rails and very soft (almost flat) down the middle/centerline…maximum lift and release for a high-perf shortie…

hth

cheers

Like meecrafty said, the width of the semi-flat through the middle of the concave is the key, and what helps it to work. And other things like the leading and trailing ramps into the concave. A ‘v’ wouldn’t come close, and may not go rail to rail very smoothly.

so, it is that the concave is curved and not flat edges,

yeah, i guess that would make it kinda hard to transfer rail to rail…although, i was thinking about under the front foot mostly.

anyway,

thanks you guys, just sitting on the couch wondering…

As Waldo would say: No prob Bob.

It doesn’t cost anything to discuss or ask questions.
