Light Weight Micro Turboprop Enigne for Outrider

Not Available Makai Ocean Engineering, Inc. proposes to evaluate the feasibility of developing a near real time modeling system to accurately determine the seafloor location of U.S. Navy acoustic arrays as they are deployed. The acoustic arrays and connected fiber-optic micro-cables will be deployed from a near bottom Towed Deployment Vehicle (TDV). Makai has previously developed a real-time cable deployment control system which has been used in a number of precision commercial and military cable lays. It is proposed that Makai's installation model and cable lay simulation software be modified and used as the primary analytical tool for this project. Cable location and array orientation results computed by existing models will be compared with measured experimental data. Discrepancies between model results and measurements will be subjected to a sensitivity analysis to identify the error source and to quantify the error magnitude. Discrepancies can be attributed to inaccuracy of input data (e.g. current meter and navigational equipment inaccuracy) and to the numerical approximations in the cable models. Several existing cable models will be evaluated to determine the modifications and effort that would be required to adapt them to Navy real-time operational and data acquisition requirements.
