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 ...

Candent Technologies has successfully developed a low cavitation, high efficiency, extremely low acoustic signature marine propulsor, and is proposing to apply this advanced technology to the design and development of a compact, efficient, electric driven, stowable/retractable, Quiet Auxiliary Propulsion System that will meet and likely surpass the requirements for the SOCR (and 11m RHIB, as well ...

Metal additive manufacturing (AM), particularly, laser powder-bed fusion (LPBF) has transformative potential to achieve geometric design freedom at low production volumes. However, porosity and localized defects remain a significant challenge to implementation in mission critical aerospace applications. While the quality of LPBF is now competitive with or surpasses castings for established materia ...

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 ...

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 ...

During Phase I, Adiabatics, Inc. will use generator “best design” technical practices as well as new proprietary technology to develop a solution for high temperature cable and connector development for radio frequency (RF) applications in harsh environments.  First, Adiabatics, Inc. will develop a heat transfer model of its proposed RF cable.  The cable includes many materials that Adiabati ...

Triton Systems proposes to develop a high-fidelity software model to simulate performance of a Thermal Protection System (TPS) for a Hypersonic Weapon with intent to integrate the software into a real-time test architecture with a hardware-in-the-loop framework. The model will be informed and validated with experimental data of a real TPS material coupon and include inputs of vehicle kinematics an ...

Physical Sciences Inc. (PSI) will develop a compact, spatially offset Raman sensor for non-contact, depth resolved measurements of solid rocket motor propellant. The Raman sensor, currently under development at PSI, will use a high throughput spatial heterodyne interferometric spectrometer (SHS). The SHS is 104 more sensitive to Raman photons than a conventional diffraction grating based slit-spec ...
