Hi! Interesting difference but as they say here "One swallow doth not a Summer make". I have a car coast-down test I'm going to adapt to conduct my ABA tests as I'm impatient to know how significant my aerodynamic improvements are. If it delivers consistent results, I will post both.
Hi! My Project is progressing very slowly.
Design based on a proven laminar flow aerofoil (Davis used on B17 Bomber wing) and Kamm tail at 55% reduction in crossectional area.
Construction using plywood and aircraft techniques progressing slowly (lots of bits cut but not yet assembled).
Will post pictures as it comes together.
Baseline fuel economy with existing panniers and topbox now completed. Will post when I have comparable data from my own aerotrunk.
Kind regards tw
