The suppression of a ship’s magnetic signature is important in the effort to thwart detection by adversarial forces and prevent engagement with magnetic fused weapons. There are two ways to model ship magnetic signatures; through the use of finite element based analytical models and through the use of physical scale models (PSM). Finite element based analytical models are less expensive and have ...

Texas Research Institute Austin, Inc. (TRI/Austin) and Florida Institute of Technology (FIT) in the Phase I effort will implement the use of a revolutionary new class of adhesives to attach C4 to underwater mines. These adhesives are extraordinarily insensitive to water, tolerant of unprepared surfaces, and offer extremely rapid cure and excellent bond strength. These materials can be applied usin ...

Texas Research Austin (TRI-Austin) will continue to partner with the University of Texas, Austin, to use additive manufacturing for fabricating and optimizing the lithium ion and electroactive metal electrode systems for which the team established proof of concept in the Phase I base period. The Aerosol Deposition Method (ADM) is a broadly applicable additive manufacturing technology that has been ...

The recent emergence of many new ocean-transiting military and domestic security threats has led to a growing need within the Department of Defense in general and within the Department of the Navy in particular for improved methods for estimating the electromagnetic vulnerability to visual/electro-optical/infrared/radar systems. Accurate characterization of the marine boundary layer (MBL) in the v ...

Next generation UV Nanotechnology based sensors are needed for a variety of Naval Systems that includes Threat detection, Hostile fire indication (HFI) and Threat Warning Applications. Magnolia as part of the proposed Phase II STTR Program plans to design, and develop high sensitivity ZnMgO/ZnO nanowire based detector arrays for next generation multicolor sensor applications. The key components of ...

In this STTR program, Photonic Systems Inc. and Prof. Jacob Khurgin at Johns Hopkins University propose novel optical external and internal fiber cooling approaches to efficiently cool the high power GaN microwave amplifier. The external cooler is a single end, square-shape, Yb:ZLAN fiber with high reflection (HR) coated surface which can attach to the amplifier surface and create a cold spot at t ...

The U.S. Navy seeks methods to improve the fuel economy of marine diesel engines through utilization of waste heat. Low temperature engine jacket water, lubrication oil, and aftercooler air are largely untapped streams of thermal energy on these ships, but their utilization circumvents many operation challenges associated with exhaust gases. For example, variable and high exhaust gas temperatures ...

The objective of this project is to develop a comprehensive suite of tools, called the DAA Radar Software Suite and Simulation (DAA-RSSS), that supports future Navy procurement and certification of non-cooperative sensor technologies for Detect And Avoid (DAA) as well as develop plans to support EO/IR sensors as the non-cooperative sensor as informed by FAA activities in developing Minimum Operati ...

Triton Systems, Inc. proposes to develop an affordable, lightweight and durable hybrid composite system for next generation structural frame composites that will survive both short- and long-term thermal and chemical exposure and abrasive conditions. The team will develop a hybrid materials system that is an improvement on traditional carbon fiber reinforced polymer (CFRP) systems in performance a ...

This STTR Phase II Proposal addresses the need for a low cost acoustic transmitter that combines a power amplifier, control-circuitry and an innovative transducer assembly, all at a low cost. Our approach is to use a cylindrical modal vector projector transducer which becomes part of the housing and, moreover, uses only a minimum of power to provide a sizable source level. The modal vector project ...
