Abstract : Raleigh-Ritz method has been applied to solve the problem of determining optimum blunt-nosed missile shapes of minimum ballistic factor. It has been found that in both the cases, i.e.,(i)lenght& diameter, and (ii)diameter and wetted area given in advance the optimum shapes are purely upto critical values of the friction parameters defined in the two cases and beyond these values the shapes are regular followed by cylinders. |
