Friction Stir Welding of High-Melting-Temperature Materials with the Aid of Auxiliary Heating Sources

Not Available Combat systems have historically been developed through a process that focuses on insular subsystems. This process has resulted in severe limitations on system interoperability and technical obsolescence. In addition, excessive life cycle costs are associated with maintaining multiple configurations to ensure some level of interoperability. To overcome these limitations, new emphasis has been placed on the use of Commercial Off-The-Shelf (COTS) technologies. To support the use of COTS, DSR has developed a real-time middleware framework for integrated combat systems and joint warfare coordination systems that is becoming widely used in the Navy. Transportable Middleware (TM) permits software developers to take advantage of the continuing technology advances in the commercial computing industry, because application software can be ported quickly. TM is being applied to the Cooperative Engagement Capability Processor (CEP) because of the desire to use a common software baseline on many different hosts located on different platforms. The overall objective of this Phase I research is to extend TM by designing a suite of test and performance analysis tools that will minimize the need for complete regression testing when introducing new hardware and software. The ultimate goal is minimizing life-cycle cost, which is particularly crucial to the CEC Program.
