The US Navy is seeking ways to treat typical ship-generated waste to minimize storage space required for waste storage during long-term deployments, with a special emphasis on the large items produced during cargo and ordinance handling. The best way to do this is to treat the waste as a resource, reducing its volume and producing useful energy or fuel from the waste decomposition process. Rather ...

The Undersea Warfare Decision Support System (USW-DSS), currently employed by Carrier Strike Groups for integrated command and control and anti-submarine warfare (ASW), uses the Operational Route Planner (ORP) that incorporates a genetic algorithm to define optimal ASW search tracks. This capability does not currently consider route planning and supporting ASW operations in the context of avoiding ...

Applied Physical Sciences and the University of Maryland propose to develop a magnetostrictive transducer that harvests electrical energy from shipboard machinery while simultaneously suppressing vibration to improve the ship’s stealth characteristics and thereby improving the performance of hull mounted sonar systems. Analysis performed during the Base Effort will provide an initial design spec ...

Applied Physical Sciences (APS) and the Pennsylvania State University Applied Research Laboratory (ARL/PSU) will collaborate in the development of a novel sensor system to measure the low frequency acoustic pressures within a fluid-filled pipe. The proposed concept improves upon the Navy’s current Array Based Acoustic Measurement (ABAM) system for laboratory characterization of full-scale piping ...

Applied Physical Sciences as the prime contractor and Undersea Sensor Systems, Inc. as the subcontractor propose an innovative approach to develop an air-deployed sonobuoy system having an array gain of at least 24 dB. The approach involves an array of subminiature vector sensors coupled to sophisticated in-buoy signal processing algorithms designed to provide the requisite data compression so tha ...

Under this NAVAIR SBIR Phase II.5 Continued Development (CD) effort Applied Physical Sciences Corp. will develop and demonstrate the hardware and software for a proof-of-concept experiment in which advanced array and signal processing technology is used to help detect an underwater target. Vector hydrophones and low-power computing electronics will enable an acoustic receiver system that can explo ...

Applied Physical Sciences Corp. proposes to develop a Marine Mammal Mitigation Miniature Acoustic Detection Subsystem (MADS) for the AN/SSQ-125 active source sonobuoy or similar system. MADS will consist of a miniature high-frequency active sonar array for detection and tracking of marine mammals within a nominal 300-m standoff distance from the high-power sonobuoy source. An initial design and pe ...

The Intelligent Sensor Node (ISN) Phase I program successfully demonstrated the feasibility of implementing a high temperature capable, reconfigurable node that can interface with most types of control sensors found in today’s propulsion control systems. The proposed Phase II program is aimed at transitioning this design into a fully thermally compliant, miniaturized node that has been validated ...

A software tool for fracture evaluation and load deflection prediction of welded aluminum ship structures subjected to impulsive loading will be developed by enhancing and integrating an existing extended finite element method (XFEM) for dynamic fracture of thin shells in Abaqus. The software package will be able to model arbitrary crack paths as dictated by the physics of the scenario, completely ...

This research investigates the feasibility of improving operational readiness, reliability and availability of high current cryogenic rf linear accelerators using a cryogenic compatible resonant coupling technique to couple all of the accelerator sections together, including any room temperature portion. This technique guarantees a single resonant frequency for the system insuring rapid turn on. T ...
