Kamm's asymmetrical wing section (much like a Clark-Y),with its aft section chopped off in 7 contiguous,equal-length segments registered a drag increase of:
*14%
*135%
*166%
*204%
*245%
*288%
*333%
--------------------------------------------------------------------------
Kamm's symmetrical airfoil,of 6-different aspect ratio configurations, created by shortening the aft portion,plus the airfoil,with no aft section at all registered:
*0%
*109%
*146%
*192%
*246%
*338%
*892%
--------------------------------------------------------------------------
Kosin and Lehmann's streamline body of revolution,chopped off in 10% increments registered drag increases of:
*0%
*3.03%
*12.12%
*28.8%
*59.1%
*200%
*256%
*330%
*425%
*567%
------------------------------------------------------------------------
These are just naked bodies,in free flight,with no wheels or anything else attached,but you can clearly see the drag penalty as the pressure drag builds from each successive truncation or shortening.
