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 ...

The Physical Sciences Inc. (PSI) Team consisting of PSI, Draper Laboratories (Draper), and an airframe integrator are proposing a tunable hybrid composite structure capable of increasing the thermal operating performance by 500 C over conventional polymer matrix composites (PMCs). Our multifunctional composite approach combines PSIs low cost quasi-isotropic Ceramic Matrix Composite (CMC) system, a ...

Oceanit proposes to develop and demonstrate novel, tailored, designer separator materials with optimized properties to maximize lithium-ion cell/battery performance, life, safety and reliability.

The Navy is continually developing new technologies to improve warfighting effectiveness. These technologies risk overloading Aircrews cognitive capacities, degrading performance. To mitigate that risk, the Navy needs a system to assess Aircrews physical and cognitive workloads unobtrusively and objectively. To meet these requirements, Charles River Analytics conducted a Phase I effort to design a ...

Reducing the violence of Slow Cook-Off (SCO) and Fast Cook-Off (FCO) to acceptable levels is of great interest to the Insensitive Munitions development. For example, the MIL-STD-2105C SCO test for Insensitive Munitions (IM) compliance requires a slow heating rate (3.3°C/hr) until reaction occurs whereby the ensuing reaction is characterized by degree of violence. A Type V (burn) reaction or bette ...

The U.S. Navy currently utilizes a number of towed systems from surface ship and submarines for sensing and communication applications. In a number of these cases, a tow cable extends either down from a surface ship or up from a submarine through the upper part of the water column where seawater temperature can be both highly variable vs. depth and dynamic in time and geographic location. Having a ...

To provide power for unmanned aircraft systems (UAS), we propose developing solar cells made using perovskite halide solar absorbers, such as those based upon methylammonium lead iodide (CH3NH3PbI3). Our phase I efforts produced flexible solar cells that exhibited power conversion efficiencies (PCE) of 8.1%, a landmark achievement. The proposed research details how to achieve 20% power conversion ...

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 ...
