Front Wing Design Possiblities

[flynfrog]

Can someone actually discuss the question/proposal instead of throwing around vague and pointless derogatory comments.

well you seem so sure what is there left to discuss.

Not sure about the whole airbrake thing wesley, sounds a little OTT. Look at it another way: It certainly won't create less DF cause the main plane has essentially been moved forward with increased AoA and a sort of fairing has been added to maintain the seal in front of the wheels. Since the second (rearmost) element can be designed with drag reduction in mind (rather than DF) and the front element should generate more DF (leverage and increased AoA).

To answer your question no it wont work. It will create much more drag and probably less downforce. Look up how a multielement wing works. You wan the flow to "pass" from one element to the next. Your wing is choking most of the second element off and you are making your first element trying to force air into your second element.

If I was so sure I wouldn't have asked would I but thanks anyway. But to focus more on the drag reduction method now: There are flaps mounted vertically beneath the wing to send it around the tires so how can they work if sending the air upwards won't when that is where its going anyway. (thinking of doing both though)

A system like this perhaps:

I recall something similar on mid 90's RWs but i cant be sure. In fact your pic has something a little like it.

BTW how is the first element forcing air into the second.

the rearmost element is still suffering from the same problem as in the original design; its just smaller, so perhaps less effect. The goal these days is not really to generate more downforce. thats a pretty simple proposition, just increase AoA. the goal is to generate the same df with less drag, ie efficiency. thus, red bull has a small element on their front wing that helps feed the diffuser. I don't really see how your wing accomplishes something similar. Adding more elements is not the answer; Boeing switched from triple slotted flaps to single slotted flaps because they had less drag. at the same time, advances in aerodynamics meant that they were able to generate adequate performance from a 1 slot flap.

To keep flow attached then? that alows more AoA.

Anyway I'm trying to run the wing as far forward as possible for better leverage. Renault did that in '09. Not that that was very effective. Still they ran hardly any AoA originally. If DF can be increased in front of the tire (when it will cause drag anyway) then you can have much less AoA along the rest of the wing and therefore better flow to rear of car.

More leverage just would give you more front balance authority from the front wing.
No effect on total downforce, and more difficult to compensate a powerful front wing with rear downforce.

Think i've said this before but...
Make the fw more efficient and then run less fw inboard. Then you don't need more rw and more air goes to the back of the car so greater efficiency there too. And less fw drag in theory (as long as the AoA is not to high).
