So I came across this concept today, one I had never seen before:
Found it in this document:
http://www.diva-portal.se/smash/get/...FULLTEXT01.pdf
Which compares full scale vs model (1/5th scale) in same wind tunnel. Results from above front inner fender concept are:
-.003 to -.006 drag reduction. (-.003 what the full scale model showed, -.006 what the 1/5 scale model showed)
Has anyone ever done/considered this?
