Welcome to The CTMA Connector, a monthly newsletter designed to provide news and ideas about the Commercial Technologies for Maintenance Activities (CTMA) program. The CTMA program is a joint Department of Defense/National Center for Manufacturing Sciences (DoD/NCMS) effort promoting collaborative technology development between industry and the DoD maintenance and repair facilities. This newsletter highlights ongoing projects, serves as a forum for promoting new project ideas, and provides other news of interest to the program. Our goal is to stimulate your participation and solicit your input. Feel free to submit items for the newsletter as well as any suggestions to make it more useful. More information about the program can be found at http://ctma.ncms.org/. To subscribe or unsubscribe to the CTMA Connector, send a message to listserv@listserv.ncms.org with “subscribe CTMANewsletter” or “unsubscribe CTMANewsletter” in the message body. We welcome the following companies into NCMS: One Network Enterprises, Inc. (www.onenework.com) One Network Enterprises provides planning, execution, and business intelligence applications built on a federated cloud computing platform. Committed to embrace, not replace, existing technology, One Network enables companies to achieve unprecedented visibility and collaboration that supports synchronized end-to-end business processes, improved insight, and better decision-making. SenGenuity (www.sengenuity.com) SenGenuity’s mission is to bring to market highly differentiated sensor solutions based on Surface Acoustic Wave (SAW) and Bulk Acoustic Wave (BAW) technologies. Navy Maintenance and Repair Project Partnership (NMRPP) Using Navy funds MIPRed through the CTMA Cooperative agreement, the NMRPP program is specifically focusing upon technology needs at the shipyards. Three projects are currently being formed: Reduction and Control of Emissions During Metal Cutting OperationsThis project will include 3 phases:
Catapult Laser Alignment Position Measurement AutomationThe phases of this project include:
New Technology Metal Deposition Repair for Navy Ship/Submarine Components NUWC Keyport, NCMS, and Project Partners will implement existing metal deposition technologies to develop repair processes for high value Fleet components in support of PSNS&IMF. NUWC Keyport has identified a number of shipyard repair applications in need of improved repair processes. Scope of project will be to perform component selection/ROI analysis, repair process development, metallurgical analysis and obtain NAVSEA certification approval for up to three Fleet components. Specific deliverable will be NAVSEA approved repair processes which enable components to be reissued to the Fleet. The NCMS Program Manager for NMRPP is Tony Haynes, tonyh@ncms.org, 734-995-4930. Recently Approved CTMA Project: Corrosion Resistant Solid State Thin-Walled Component Joining for Maintenance and Repair ApplicationsDoD Participants: U. S. Army PM Tactical Vehicles (TACOM); U.S. Army TARDEC; U.S. Marine Corps PEO Land Systems; U.S. Marine Corps Systems Command Director Ground Transportation & Engineering Systems; U.S. Marine Corps CG LOGCOM The DoD continues to seek new welding and joining technologies to decrease repair cycles while increasing weld quality for a wide variety of components. This project is specifically targeting one of the more challenging classes of weld repair and fabrication thin-walled components. Thin-walled components often require the use of the highest skilled welding artisans within the depot infrastructure due to the intricate nature of avoiding burn through and component thermal warping. To avoid this, thin-walled components (common in nearly every military platform) are often over-engineered or buttressed with thicker metal reinforcements to handle the thermal load of conventional MIG and TIG joining. These countermeasures add significant unwanted weight to the platform and also increase the corrosion prone weld filler regions that results from conventional welding. This project seeks to develop and test a new solid state joining method that does not melt the materials to be joined thus increasing dimensional accuracy, corrosion resistance, and weld cycle time. The new state-of-the-art technology to be explored in this project stems from the use of a novel manufacturing method called Deformation Resistance Welding (DRW), which can be utilized to join a wide variety of thin-walled components common to virtually every DoD platform. Further, the DRW technology can be readily retrofitted into any depot facility for rapid utilization as the fundamental technology is based upon the well-known principles of resistance spot welding yet applied to large components of many shapes and sizes.

Recently Approved CTMA Project: Improved Stealth and Lower Cost Operations for U.S. Naval Ships using High-Performance Cordage Deck Edge Netting DoD Participants: Naval Surface Warfare Center Carderock Division; Naval Sea Systems Command At present, the U.S. Navy uses two styles of deck edge netting: metallic cord netting that is durable however is very heavy and difficult to repair shipboard as well as add to a ships radar cross section. The other netting that is used is nylon netting that is lightweight and has no radar signature. However, the nylon nets typically get replaced every 18 to 24 months due to UV degradation, shrinkage and abrasion. QinteQ North America, Technology Solutions Group developed a cordage net that is lightweight, has no radar signature with a Navy tested life of five years. This netting is machine-made and finished to custom sizes and promises reduced lifecycle cost. The primary objective for this project is to extend the use of High-Performance Cordage Deck Edge Netting (HPC DEN) in lieu of nylon strap netting by installing developmental square HPC DEN Spectra/polyester cordage aboard a U.S. Navy test fleet that will be determined. The number of nets is dependent upon the vessel that will be available for the net installation. The estimated cost savings are based on the assumption that a ship set currently costs $30K to $40K for eighteen to twenty-four months of life in addition to testing costs at the twelve month interval. The new HPC DEN cordage has a life expectancy of six years at a cost of $40K which would provide a projected cost savings of $80K. The estimated readiness benefit is based on the elimination of two to three other maintenance requirements and adding one month to ship readiness. The assumption is the new netting is projected to last four years longer that the current netting If one year equates to one week, one month would be added to ship readiness.
