RE: base drag

Find a copy of _Fluid Dynamic Drag_, by William F. Hoerner.  The book is self-published, and the author deceased, but I think still available from family.  One of the best compilations of fluid dynamic data I've ever seen.  From a brief web search:

HOERNER FLUID DYNAMICS
P.O. Box 21992
Bakersfield, CA 93390
Phone/Fax: (661)665-1065
hfdy@hoernerfdy.com

Or check in local engineering library.


RE: base drag

Oops, you're correct, it's Sighard Hoerner.  For some reason William Hoerner sticks in my mind...was he maybe some WWII German aero designer?

RE: base drag

RE: base drag

I don't know about William, but Sighard Hoerner (or perhaps it would have been Hörner if the "¨" had been more widespread?) was, I'm told, in fact a WWII German aero designer.

Best regards,
Soeren (that should have been "ø" if that had been more widespread!)
