Does anyone have a formula to approximate the amount of downforce created by a splitter? I have the McBeath and Katz books and there are no formulas I can find, or even any approximations. Seems like everything out there is done with real-world data.
I have a short diesel pusher RV, and the combination of short wheelbase and the monster Cat hanging off the back can make handling a bit sketchy. The manufacturer installed about 200 lb of steel between the front frame rails. I added a 3x4 tube bumper (full of brick right now but collecting rebar) and a 25 gallon Ag sprayer behind the front cap which is also used to cool off the diesel on long hot climbs.
But let the fuel get below a half-tank on a windy day and it gets tiring.
So given how flat the front is, thought I could make a 9 ft wide splitter. The cap is 1/4" thick, so supporting it shouldn't be too difficult. But there's no reason to do it if I can't get more than a couple hundred pounds at 60mph.
