Historically, active materials (Navy Type III) used in compact, low cost Navy sonars, such as A-size sonobuoys have moderate d33 and low loss factor. Recent developments in lead-based textured ceramic with properties between those of conventional PZT ceramics and relaxor single crystals can improve the performance of these systems, but need to be manufactured at high volume and low cost. Most appr ...

Triton Systems proposes to develop a Silent, Deployable, and Rugged Ocean Propulsor (S-DROP) for use on small naval combatant craft. S-DROP will provide a secondary propulsion system for silent running stealth operations in a modular, cross compatible, and scalable package without compromising existing systems. S-DROP incorporates extreme ruggedness and acoustic quieting techniques with high perfo ...

The Navy utilizes small, crewed watercraft, e.g., the Special Operations Craft – Ravine, for a range of missions in the littoral zone. These watercrafts, while designed for high-speed operation, also require low-speed stealth operation to successfully complete all types of mission objectives. However, the existing internal combustions engines and propulsion systems currently used on these vessel ...

Additive Manufacturing provides many potential advantages, relative to traditional manufacturing methods, for the Navy and other organizations in the aerospace community.  Although flight critical aerospace quality metal alloy components have been produced and flight tested, confidently expanding the use of AM in these applications requiring stringent quality control and repeatability. The vendor ...

While AM systems, especially metal AM, bring revolutionary capabilities and have the potential to reduce supply chain issues and enable new designs through unique layer-by-layer fabrication capabilities, AM technologies currently suffer from defects that exist within the components. Defects such as porosity, inclusions, large-scale voids, and chemical inconsistencies can inhibit the functional per ...

In response to the Navy’s need for an AI-enabled multi-attribute generation system, IERUS Technologies proposes to determine the technical feasibility, design and prototype for a system that can be fully integrated with proper associative databases to monitor and track developing activities/signals in all operational domains. This prototype architecture will extract meta-data attributes from exi ...

Emergingdx Inc in collaboration with academic and industry partners will design and develop a novel rebreather. The new design will (i) provide oxygen and/or eliminate CO2 at a rate to match metabolic rates of an active diver in missions lasting up to 10 hours (ii) be modular so that it can be easily disassembled, cleaned, disinfected, and dried, (iii) have similar or smaller formfactor than curr ...

Age and environmental exposure can alter mechanical properties of solid rocket propellants, which can cause problems with functioning.  Understanding the mechanical state of the solid rocket motor propellant allows for a better evaluation of the health of the propellant and provide greater fidelity in aging trend evaluations. The Navy has a need for a compact sensor or a suite of sensors that c ...

Propellant aging is a critical factor to monitor when estimating the remaining solid rocket motor service life – when critical mechanical property limits are reached, the motor violates safety requirements and should no longer be used. Current lot testing diagnostics protocols lead to costly premature disposal of valuable assets and can significantly reduce the warfighter inventory to counter ex ...

Systems Visions LLC (dba SYVI) has identified possible solutions to create coaxial cables capable of operating at extreme temperatures. The High Efficiency Refractory Metal Enhanced Survivability (HERMES) cables will be comprised of refractory metals and ribbon ceramic materials. The HERMES cable solution should function in excess of 1500 degrees Celsius. We will also develop an appropriate measur ...
