ON OPTIMUM FORM OF GROUND-THROWER'S BLADE

Cover Page

Abstract


Method of determination of ground-thrower's blade optimum form is based on solution of brachistochrone problem for the field of centrifugal inertial forces. Blade of optimal shape, called brachistochrone, in the centrifugal force field, which equation had been obtained in polar coordinate system, is considered. The results of kinematic behaviour researches of mov- ing particle are given.
