A dome connector for a flywheel rim to shaft attachment is provided. The dome connector includes a helically wound composite band that extends from a first port to a second port. The helically wound composite band has a helical angle in relation to a line perpendicular to a center of axis of the dome connector. The helical angle is selected to at least in part achieve a desired stiffness in the dome connector.

Pressure vessel end dome reinforcements are placed upon resin-impregnated fiber-wound pressure vessels to improve the strength-to-weight ratio of high performance pressure vessels, such as those that are used as rocket motors, gas generators, and the like. The reinforcement structures are assembled from gore pieces to form gore bodies over dome regions of the pressure vessels.
