Raman spectroscopy is a non-destructive optical technique for detecting molecules on a sample surface, and it is well-suited for the quantification of organic molecules within a mixture. Convenient hand-held Raman spectroscopes are currently manufactured by Ocean Optics, a recognized world leader in the manufacture of miniaturized spectrometers, and we propose to customize one for specific use by ...

The predictive understanding of Radio Frequency electromagnetic propagation is critical for the performance of Navy systems. To acquire the necessary data, the Navy needs a system integrated with the ScanEagle Unmanned Aerial Vehicle (UAV) capable of analyzing distant signals of opportunity while meeting strict Size, Weight, and Power (SWaP) requirements placed on hardware payloads. To meet this n ...

Makai proposes to complete a parametric analysis of candidate sonobuoy components for a conceptual deep drifting sonobuoy system. These results will enable the Navy to perform a tradeoff analysis of the sonobuoy system to meet their operational requirements and form-factor constraint. Using Navy-supplied location data, Makai will characterize the ocean environment in the area of operation and us ...

A unique undersea acoustic phenomenon called Reliable Acoustic Path (RAP) offers an opportunity for a paradigm shift in air-ASW CONOPS. In areas where the ocean reaches sufficient depths, the density of the water increases to the point where the speed of sound exceeds that at the surface. An acoustic receiver placed below this critical depth benefits from greatly improved signal to noise ratio. Th ...

Future hypersonic vehicles will be required to fly extended, long term trajectories where the bod-ies must exhibit high lift-to-drag (L/D) ratios. The need for reduced drag means that the nosetips and leading edges must have small radii, shallow wedge angles, and be erosion resistant. Desira-ble dimensions include a nose radius on the order of 0.040 inch and a wedge half angle of about 3. This rad ...

Todays Navy electronics maintenance training largely focuses on proceduralization of diagnosis and repair, rather than deep systems knowledge. This training is effective at producing durable skills for common systems, but brittle, especially for dealing with unique characteristics and properties of actual shipboard systems. With continuing modernization of equipment and growing unavailability of s ...

The goal of this Phase I program is to develop broadband single crystal sonar for the ATT. Single crystal piezoelectric is a high energy density, highly efficient piezoelectric material that is being used to develop acoustic and ultrasonic transducers with bandwidths much higher than has been possible with conventional ceramic materials. For sonar, broad bandwidth is especially important for opera ...

TRS Technologies, Inc. proposes to develop volume efficient, fast discharge, high breakdown strength capacitors with stable dielectric properties for utilization in pulse power systems. The proposed ceramic capacitor will combine the best features of high energy density, low dielectric loss and high reliability. The capacitors developed on this program will have an energy density >0.6J/cc, low pow ...

We propose to develop polymer-based negative-positive-zero (NPO) capacitors by combining our proprietary dielectric formulations, film processing technology, and unique capacitor design. As polymer film capacitors have intrinsically high dielectric breakdown strength than multilayer ceramic capacitors (MLCC), our capacitors will be able to provide high operation voltage > 80 kV. The dielectric for ...

In this SBIR program, Advanced Cooling Technologies, Inc. (ACT) proposes a PCM-based ocean thermal energy harvesting system to provide reliable, renewable, on-board electrical generation for autonomous underwater vehicles and platforms. This affordable and scalable system harvests energy from the natural temperature gradients that exist in the ocean. ACTs novel design efficiently extracts heat fro ...
