A filament-wound pressure vessel having a pressure vessel liner (10) and a continuous filament polar (14) wound over the surface of the liner (10) in an isotensoid pattern. The liner (10) has a geodesic dome surface (16, 18) extending between a diameter (24) of the liner (10) and a polar opening (12). The dome surface (16, 18) is defined by oppositely curving surfaces of revolution (22, 30) of a meridia joined by an inflection point (32, X2). The first surface of revolution (22) curves from the liner diameter (24) to a first point (Y2) just unto but not at said inflection point (X2). The second surface of revolution (30) curves from the polar opening (12) to a second point (Y3) just unto but not at said inflection point (Y2) in a direction opposite the curvature of the first surface of revolution (22). The first and second surfaces (22, 30) are joined, and the inflection point (X2) is traversed by a straight line third surface of revolution (42) closely approximating geodesic curvature through the inflection point (X2). <IMAGE> |
