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 ...

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 ...

Many rocket motors used by the Navy are powered using solid rocket propellants (SRP). Over time and with exposure to varying environmental conditions, the elastomeric binder material undergoes oxidative degradation leading to embrittlement of the SRP.  Current methods of non-destructive testing (NDT) using ultrasound exist to inspect SRPs for major defects that occur when aged SRPs exhibiting suc ...

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 ...

Cornerstone Research Group Inc. proposes to advance the state-of-the-art in mechanically toughened, weather resistant CMC composites by combining recent advances in 2.5D and 3D architecture technologies, and plasma deposition processes, with a CRG proprietary resin system called MG Resin. Addressing the need for affordable hot structures, MG Resin has proven to be an excellent material for replaci ...

The objective of Phase I is to determine an optimal antenna array design and frequency band of operation to achieve reliable communication in the presence of plasma from glide body separation to terminal phase. Candidate designs will be identified and analyzed in Phase I and will be prototyped and tested in Phase II.  Exo-Atmospheric Technologies will develop a simple, lightweight Deployable Hype ...
