ABSTRACT:
A reduced-drag, axially symmetrical missile or submarine hull with rounded, tapered bow and stern portions, and a rounded central portion tapered, for drag minimization, along a curve defined by a Fredholm equation of the second kind framed so that the pressure coefficient remains constant at all points on the central portion. The missile is designed to travel within a fluid so that its drag coefficient is decreased, boundary layer detachment is avoided, and cavitation and instability phenomena are eliminated. The constant pressure coefficient is reached by following as a profile the natural track lines of the front portion which are joined to the rear portion.
