PHOTO-Update# 2-A ( T-100 tuft study )

I've got some pics of the trailer I'll try to post today but wanted to put this up first.I posted this also at the aerodynamic template thread. The photo was taken a couple years ago.What's important to the trailer project,is that the articulated gap-fillers take the place of the boat tail,providing the "bridge" between the truck/trailer( 20% drag for a conventional trailer ).---------- Theory suggests that if the flow can follow onto the trailer without separation,and then continue to the end of the boat tail,then there will be no wake.--------------- From the photo,you see fully attached flow to the back of the boat tail.That's all you could hope for.With the streamlining kit and trailer,the wake is reduced from 29-square feet,to 1.5-square feet,a 95% reduction.
