I've done tons of searching, but I haven't been able to find if anyone knows the coefficient of lift for a 914? I've found lots of Cd and Ca numbers, but I need the Cl for some data work.
Thanks! |

Actually, almost all cars generate positive lift at some speeds. Fortunately, that lift is very rarely equal to or greater than the actual weight of the car. Generating 100 lbs of lift doesn't come close to counteracting 3000 lbs of weight. It can make high-speed corners more interesting than they have to be, though....
It is certainly true that a car is in ground-effect while an aircraft is not. But the equation should still give at least an approximation of the Cl for the car, since we do know a lift force. --DD |
