A long-overdue overhaul. The physics has been redone and some typos corrected. It has also been re-calibrated and the paper explains the concepts involved in more detail. The paper also refers to Mont Hubbard's work in relevant locations.
New version 09/Aug/2005
An analysis of the physics and mathematics of javelin flight. The resulting model is implemented in the software referenced below. As far as I know, this is the only publicly available model which handles all the significant factors including the effective attack angle. It contains a few surprises for javelin throwers and debunks some popular myths.
When I wrote this I was ignorant of the extensive and important contributions of Professor Mont Hubbard of the University of California at Davis. When I contacted him, Mont kindly gave me copies of a number of his papers. His work is full of important insights and should be studied by all interested in this field.
