Triton Systems proposes to provide for the Navy the Improved Air Deployable Acoustic Receiver (ADAR) Sonobuoy Structure, which will expand the acoustic range of the AN/SSQ-101 sonobuoy into low frequencies and will provide improved capability to detect, classify, locate, and track submarines and other sonar contacts.

The main objective is to design, build and test a low-profile, high-power, low-frequency broadband, d36 shear-mode piezoelectric single crystal transducer capable of operating at submarine depths. Because of Phase I program constraints, we designed an initial modified shear mode transducer with a nylon cylinder head-suspension, that would be used in a d36 design capable of operating at submarine d ...

There is an ongoing need to improve the design of low frequency, high power sonar transducers for use in underwater acoustic applications. During this Phase I Base Program, the Massa/BAE Team investigated the properties of recently developed PMN-PT textured ceramics for transduction use in transducers, and then developed designs for two different PMN-PT transducers that were based on existing PZT- ...

CAMX Power proposes to develop and demonstrate a non-contact sensor capable of measuring the torque, speed and position of unmodified shafts made of virtually any material. The multifunction shaft sensor (MFSS) will measure the torque-induced twist in the shaft using optical methods to determine precise rotational position at two points along the axis of the shaft. The proposed Phase II effort wil ...

To continue the development of Navy personnel expertise, the Navy applies intelligent tutoring systems (ITSs) coupled with training simulations to improve the efficiency and effectiveness of future training. One of the key questions is how much fidelity is required for the simulation. Instead of questionable rules of thumb, developers need scientifically validated methods and tools for understandi ...

We propose to utilize a laser 3D printing manufacturing technique to realize an ultra high efficiency micro-channel laser head cooling system with high thermal load capacity in a small volume package. The new approach incorporates key technical innovations that drastically increase the forced water flow interaction surface area and the metal thermal conductivity. The approach enables conformal geo ...

The littoral environment is especially demanding on tactical sonar systems, in large part because the spatial and temporal variability imposes sonar system operating conditions of a nature and with a scale heretofore not encountered in the open oceans. Recent Office of Naval Research (ONR) sponsored basic research as well as fleet exercises have shown that littoral environments tactically importan ...

As the number of emerging warfare capabilities increases, adaptive training is required in order to keep pace with the corresponding increase in the scale and complexity of training regimes. To enable truly adaptive training, training systems need to both (1) automatically generate training scenarios and (2) automatically assess trainee performance. Lastly, (3) diagnostic visualization technologie ...

Physical Sciences Inc. (PSI) will develop novel feedstocks for 3D printing of lithium-ion batteries using existing additive manufacturing technologies. Lithium-ion batteries simultaneously offering high energy and power density energy will be demonstrated using the novel feedstock materials. PSIs proprietary HA coating technology will be utilized in the feedstock formulations to maximize active ma ...

Demand for portable power continues to expand, and new portable devices require increased variability in form factor. Furthermore, expired batteries may not be easily replaceable due to the lack of standard geometries. New manufacturing technologies are necessary to respond to each of the challenges. Additive manufacturing (AM) is a promising approach that is well known for its ability to quickly ...
