A pipe clamp for affixing to a pipe subjected to bending to minimize fatigue for a butt weld in the pipe. The pipe clamp includes an inside clamp segment and an outside clamp segment each having a semi-cylindrical shape, a first end and a second end. An inside surface of the inside clamp segment is substantially smooth for permitting slippage of an outside surface of the pipe with respect to the inside surface of the clamp segment. The outside clamp segment has an inside surface that defines a friction element. The friction element is for gripping an outside surface of the pipe to which the outside clamp segment is affixed. A clamp mechanism is provided for securing the inside clamp segment to the outside clamp segment.

A gas storage structure includes: a container and a continuous coiled pipe supported by the container, the continuous coiled pipe including a major portion formed of thin walled pipe and a thick walled pipe defining an end of the continuous coiled pipe, the thick walled pipe having a wall thickness thicker than the thin walled pipe, the thick walled pipe being welded at a welded joint to the major portion to place an inner diameter of the thick walled pipe into communication with an inner diameter of the major portion and the thick walled pipe being connected to the container, while the major portion is free of any rigid, such as welded, connections to the container.

Since the advent of impulse launching various payloads from Navy and other military combatants, the source of the impulse energy has been either an explosive gas generator (propellant) or stored high pressure gas in a flask. Both of these methods have high maintenance and/or clean-up costs and are typically limited to one type or size of payload per launcher device. This limits operational flexibility and increases logistical complexity and cost. SEA CORP has developed a family of impulse launchers that use COTS automotive air bag inflators that significantly expands the capability and flexibility of any single launcher design to employ a number of payloads. The inflators, widely used in the automotive industry, are small cylinders containing a highly compressed inert gas that is released when a small initiator is electrically actuated. By changing the number, size, and initiation timing of the inflators, the launcher can be adjusted to accommodate various payloads that have different impulse requirements. The technology was originally developed under a NAVSEA SBIR to launch light weight torpedoes up to 740lbs from surface ships. In the proposed application, SEA CORP will adapt the technology to provide the impulse energy to eject missiles from submerged submarines.

This effort to improve the capabilities of the ESM system will increase the reliability and reduce lifecycle support costs of the Radar Wideband (RWB) subsystem on submarines. Analog to digital converter (A/D) based digital receivers will be applied to yield improvements in Radar signal acquisition and processing. In-phase and Quadrature (I/Q) data streams will be created from which intra pulse modulations may be derived. Improvements for intercept and characterization will include: shorter and longer pulse width processing, signals with dynamic pulse repetition intervals, signals with frequency agility, and solid state transmitters. This will allow the Electronic Warfare systems the capability to meet the challenges brought about by the emergence of complex Continuous Wave (CW) solid state radars that threaten the stealth and secure operations of the submarine force. This will improve the submarine mission readiness and effectiveness.

Technological advances have facilitated weapons systems capable of simultaneously supporting multiple missions leading to cost efficiencies and greater operational flexibility. Future systems capable of deploying multiple payloads from a single missile will enable various targets to be attacked with a single launch allowing more efficient use of limited and valuable resources. For such a system to work as anticipated, positive control and equipment safety of the weapons multiple payloads is critical. SEA CORP proposes the use of commercial off the shelf (COTS) automotive air bag inflators as the energetics source to release and impulse the payload from its stowed position. Inflators feature high power density, small volume, high reliability, a broad manufacturing base, clean gas output, and strict quality standards making them ideal, cost-effective candidates for applications requiring minimally-sized, power-efficient energetics packages. SEA CORP has successfully adapted inflators to launch and restrain weapons and other projectiles and to perform mechanical work and can effectively tune the inflators to conform to minimal exit velocities and maximum acceleration forces. This ensures equipment safety and effectiveness. SEA CORP only works with inflator vendors with impeccable quality and safety records and uses a different type of device than those subject to recent industry recalls.
