The Phase II effort builds on Phase I. Phase II starts with an integrated product and process design and engineering analysis of the baseline structure described in the Phase I report and variants that may reduce cost and risk. The emphasis is on use of nonlinear FEA with continuum analysis to handle stiffeners, window frames, and connectors. After review and approval by SOCOM, the design is fabricated and mechanically tested in PTI's labs, which are capable of testing a structure of this size, to validate the FEA models, the design, the fabrication process, and connectors. The structure will then be installed on a Mark V SOC craft and strain gauges will monitor its performance during an extensive period of use in normal operations. Another unique aspect of our proposal is the use of innovative software for the early identification of any changes in the performance of the structure. This patented software, SmartSignal, was developed at Argonne National Laboratory for monitoring nuclear reactors, and The Packer Group has been instrumental in its commercialization. This software is also being used to monitor the jet engines in Delta's fleet, power plants, and various industrial processes. PTI will also provide all of the support and documentation specified in the Phase II requirements.
