| Abstract: | Based on the data of aerodynamic experiment of javelins in a wind Tunnel, the flight trajectory in the different wind, such as head wind, tail wind and initial conditions are simulated and analyzed by computer with a mathematical model. The optimum release angle and change of range of javelin flight in the different wind are provided for javelin throwers and coaches. |

| Keywords: | javelin throw wind direction wind speed release angle distance of flight |
