ABSTRACT:
A filament-wound pressure vessel having a pressure vessel liner and a continuous filament polar wound over the surface of the liner in an isotensoid pattern. The liner has a geodesic dome surface extending between a diameter of the liner and a polar opening. The dome surface is defined by oppositely curving surfaces of revolution of a meridia joined by an inflection point. The first surface of revolution curves from the liner diameter to a first point just unto but not at said inflection point. The second surface of revolution curves from the polar opening to a second point just unto but not at said inflection point in a direction opposite the curvature of the first surface of revolution. The first and second surfaces are joined, and the inflection point is traversed by a straight line third surface of revolution closely approximating geodesic curvature through the inflection point.
