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 ...

The 1.5 MHz to 35 MHz HF band supports a variety of functions (including ionospheric characterization and over-the-horizon communications) with relatively little infrastructure. The large antenna sizes required present a significant challenge that has prevented the adaptation of HF systems on small platforms. Small, low free-board maritime craft have an extremely small footprint and require a mini ...

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 ...

There is a critical need for a high purity commercial source of calcium lanthanum sulfide (CaL2S4; CLS).  Ceramics made from CLS have an unusually broad range of transmittance in the infrared (IR), as well as high mechanical strength and environmental durability.  For these reasons, CLS is an ideal material for IR windows used in applications such as multispectral imaging.  CLS ceramics are not ...

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 ...

Rebreathers are scuba gear that allow the diver to breath underwater without producing bubbles. They have many benefits including light-weight, reduced risk of decompression (lack of nitrogen in the system allows the divers to stay submerged longer) and stealth (since they produce no bubbles, they don’t reveal the diver’s location).  In this closed-circuit operation, the CO2 is removed from t ...

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 ...

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 ...
