Hydrothermal vents emit large amounts of hot water, which has the potential to produce electric power. This type of power source can enable remote sea sensors and communication networks, recharge unmanned underwater vehicles, and facilitate a variety of other deep sea activities. Developing a power system for this application is challenging because the environment is extremely corrosive, mineral p ...

The introduction of Littoral Combat Ships (LCS) compounds the already challenging nature of conducting mine countermeasures (MCM) operations, which take place in a dynamic and uncertain operating environment. The MCM Commander (MCMC) needs decision aids to streamline their decision making. To meet this need, we will research and develop a suite of modular algorithms called Adaptive MCM Operations ...

ASI will leverage its recent work in small form factor HF, VHF and UHF RF direction finding to accelerate and risk reduce Navy’s Spectrum Monitoring payload. In this Phase I SBIR, ASI will deliver analysis and system descriptions for the antenna subsystem and its calibration, the RF and digital processing subsystems and ScanEagle integration. For the antenna subsystem, ASI will leverage its RF p ...

The aerospace industry commonly uses cad-plated components in aircraft structures, engines, propellers and landing gear systems in both high and low strength steels. Components manufactured from these alloys require sacrificial protective coatings due to their corrosive environments. Cadmium has traditionally been the coating of choice for threaded components and fasteners due to its many desirabl ...

MZA partnered with the University of Notre Dame proposes to transition the Navys HEFL Beam Director Subsystem (HBDS) for flight testing on the Airborne Aero-Optics Laboratory Transonic (AAOL-T) aircraft. We will reconfigure the HBDS integrating structure and aft beam control system to fit the cabin constraints of the AAOL-T aircraft with an aft beam control and scoring bench. Operational functiona ...

In this STTR, Daniel H. Wagner Associates, together with the University of Michigan (UM), will develop a Detection Avoidance System for Submarines (DASS). The proposed DASS is a set of software modules which solves the probabilistic passive sonar equation (PSE) using given environmental acoustic data, assesses submarine vulnerability based on intelligence about potential threat ASW assets, recomme ...

The objective of the present proposal is to develop and apply accurate, robust and cost-effective methodologies for the prediction of the interior nozzle flow, seamlessly coupled with high-fidelity large eddy simulation (LES) for the prediction of the jet plume and radiated noise. Based on the Phase I results, the meshing strategy and the wall modeling inside the nozzle were identified as the two ...

The Navy has a need to control such extreme power specifications that no suitable switches exist. The Navy power specifications require us to develop a novel medium (probably a pressurized gas or liquid) that can be configured to meet the requirements and control the flow of electrical power directly. Our extensive switching expertise has allowed us to develop a series of novel test fixtures and t ...

SI2 Technologies, Inc. (SI2) proposes to accelerate development of printed, high-efficiency phased arrays operating at Navy-relevant frequencies. The proposed development effort will include optimization of the array printing techniques from Phase I to meet the Navys phased array performance goals. The printed arrays will incorporate both printed radiating elements and an innovative printed packag ...

TDA proposes to continue their work on both corrosion sensor development and predictive modeling of corrosion damage with the vision of integrating sensor and modelling for adaptive prognosis of corrosion damage initiation in a unified framework. TDA focuses its research to understand the crack initiation from different electrochemical conditions and corrosion-deformation interaction effects in or ...
