This project has languished now for years (seems to be my standard operating procedure!
).
I'm creating a segmented tail for the truck,which,when combined with a fake single wheel and fairing,will be measured at the DARKO wind tunnel,to simulate a fully-gap-filled,(nearly)-full-boat-tailed,1-wheel trailer.
Rather than try to figure something out from on-road testing,this will be a way to isolate and capture aero data in a laboratory setting, where all other variables can be ruled out.
I've been especially curious about the potential for BamZipPow's Dark Shadow,1-wheeler,and this will be a way to 'look' at it with a proxy.
Testing is set for September 15,2017.
