Mocking up some canards. i like the extra large garage vary one like charlies miata has but want to do something different. Can you guys poke holes in this concept on why it will or wont work well. The first pic was my inspiration but i don't know how he keeps the air off the tire so added my own twist to it.
I don't claim to know the first thing about aero but wouldn't you want to cover up that little bit of tire between the top of the cardboard and the bottom of the fender (where it meets the bumper)?
Subbed because I want to make canards too at some point.
EDIT: never mind I see the fender flare covers up most of it
That's what I was worried about. And if I leave the back open then I'll be scooping air under the tires. Should I just stick to something more traditional. What do you suggest blackbird I know you have a lot of knowledge on all this.
Scooping a lot of air and then trying to cram it through the small hole at back is likely to result in a lot of drag.
That would be my take as well. Those canards would be more efficient if you blocked off the lower opening. Canards are generally low lift/drag ratio no matter what you do (less efficient). I view that as a last ditch solution if more down force is needed unless you have a bunch of power to spare near your average speed on a given lap.
Mocked this up to something more traditional should be mostly good right? Also starting to mock up an underbody and diffuser. So more cardboard pictures to come.
I like your original design. if you found out the area of the opening and the outlet subtract your brake duct from the same area, im sure you would have some pretty good ducting and flow.
maybe even a little vertical gurney flap.
stealing this design when I get around to building my canards... there isn't a good spot on my car to grab air for a brake duct. (jdm Toyota cresta front end on a Cressida)

I liked the original design as well, but I dont think you can really make that work well without a good CFD model. Hes going to stall a bunch of air under the wing, but get high velocity and low pressure at the outlet from it and do all sorts of weird vortices stuff down the outside the car that that could potentially reduce a bunch of drag, or not.
