Abstract : A unified treatment is given to the problem of finding minimum total drag bodies-both two-dimensional as well as axisymmetric by using Newton-Busemann law under the assumption that the friction coefficient is constant. Particular cases have been discussed when two of the geometric quantities the body have prescribed values, and the results have been illustrated by means of graphs. In case of two dimensional bodies when the length is specified and in case of axisymmetric bodies when the surface area in known, the optimum shapes are independent of the friction coefficient. |
