I have a question that I hope I can explain clearly enough that someone can help me with an answer or a good guess.
The body on my lakester will resemble some of the motorcyle liners, such as Ack Attack and EZ-Hook. But being a lakester the wheels/tires will be expose and will be moved out from the body so that their inner most planes will be at least 12-14 inchs from the body sides. I will have a neutral wing, kind of like, pod going down the body sides that will cover the axles, control arms and suspension components similar to the now gone Hammond lakester or like the bottom airfoil in the drawing above.
Now the longer this gets the more surface drag I'm going to have. If I broke it up into two shorter airfoils like at the top of the drawing and the airfoils were very close together (tail to nose) then I think that would have more drag than the one longer one. But if you moved the two airfoils apart a certain distance (
|<---- A ---->| ), then I would think that the overall drag would be lower than the one long one with the long top and bottom component.
So the question is how far apart would the two airfoils have to be from each other before I would derive a benifit?
The airfoils wil be about 7 inches thick and would have to be a minimum of about 3 feet long to cover the axles, etc. with an average width of about 12-14 inches. They would also be in the same plane with each other and the same size. The long one right now is about 12-14 feet long from it's leading edge to the trailing edge. That means the way I'm setup now there could possibly be 6-8 feet between them.
The long single one does have the benifit of giving me more room on the car for things like intercooler icewater, cooling water, and/or fire extinguishers.
Thanks and c ya,
