ABSTRACT:
Flow path defining means such as curved conduits, ducts, spillways, engine manifolds and ports, vehicle bodies, missiles and other means defining interior or exterior flow paths for fluids may be designed and generated through the use of a modified super-elliptical equation applied to cross sections between the ends to establish the coordinates of the boundary surface of the flow path. An optional coordinate transformation system and other features are also disclosed.
