Abstract
The path of discus flight and the effects of the throwvelocity/angle, spin and wind conditions on discus flight are discussed inthis paper, considering the aerodynamic force on the discus. The theoreticaland experimental investigations of discus flight indicate the followinguseful conclusions: the optimum combination of throw angle and discusinclination angle is 35°/26° at zero wind, while 45° is not thebest release angle due to the aerodynamic force; different combinations ofthrow angle and inclination angle should be adopted according to local windconditions; a spin speed of 25 r/s when releasing the discus is enough tostabilize the discus's initial orientation.
