✦ Synopsis

A method of constructing non-conical three-dimensional bodies of minimum drag is proposed assuming that the force of the medium acting on an element of the body surface depends only on the orientation of the element with respect to the direction of motion. For a specified base area and maximum permissible length of the body, the shape of these bodies is formed by combinations of parts of the surface of a circular cone and planes, the normal to which makes a certain optimum angle with the direction of motion. It is shown that the cross-section of the optimum body may be asymmetrical but the force acting on the body has no component in a plane perpendicular to the direction of motion.
