how steep an angle can you go before losing laminar flow? I am wondering if you can make the angle higher and the tail SHORTER and get the same results. the flow seems awfully stable on top. it should be JUST on the verge of going unstable to be at optimum.

I ask because I am driving out to colorado next summer in my van. I am thinking of adding a giant boat tail to the back that will pivot UP onto the roof when I am parking etc.. (the van is already longer than some parking spaces so permanent tail would be a big nono :-)

The shorter I can make it the better!
