An elastomeric disk for use in an elastomeric ejection system in which a thickened curvature protrudes from both sides of a central plane of the disk. Integral to each curvature is an annulet which dovetails from the curvatures to a periphery of the disk. The thickness of the annulet in regard to the central plane is greater on the fluid pressure side of the disk thereby shifting material strain to the center of the disk during expanding deformation. The annulet shape is attachable to the elastomeric ejection system by a clamp of the system.

Asymetrically contoured elastomeric disk

There is presented an elastomeric pump including a rigid outer housing deing an outer chamber and having a fluid inlet thereinto. The pump further includes an inner housing disposed within the outer housing. The inner housing is provided with rigid walls and first and second expandable members, the first expandable member having greater elasticity than the second expandable member, the rigid walls and expandable members defining an inner chamber. A fluid conduit extends from the inner chamber to the exterior of the outer housing. A rigid cage is fixed to the inner housing and is disposed over the first expandable member, and is configured to permit and limit expansion of the first expandable member.

Elastomeric pump

An elastomeric impulse energy storage and transfer system comprising an amulator body of elastomeric material, the body having an opening at a base portion thereof, the body having in elevation a frusto-ellipsoidal configuration, and the body taken along a sectional plane parallel with the base portion having an ellipsoidal configuration, the body being adapted to receive and discharge fluid through the opening, the body being expandable and contractible in response to receiving and discharging, respectively, the fluid, the body being adapted to retain the frusto-ellipsoidal and ellipsoidal configurations when in an expanded condition, and a submarine projectile launch system having the accumulator body as a component thereof.
