The advancement of our Nations ranging and communications systems is a crucial component for protecting national security. New and innovative technologies help to maintain our advantages on the battlefield, particularly when the combat capabilities of our adversaries continue to advance. For example, dramatic improvements to the size, weight, and power (SWaP) of radar and communications systems co ...

US Army utilizes a wide range of vehicles across ground and air platforms where mechanical transmissions are used to transmit power from the engine to the drive shaft. Gears are used to create a torque and speed conversion with mechanical contact between the gear teeth surfaces. Lubrication is necessary to create a protective film between rolling and sliding surfaces as well as provide sufficient ...

The current state of the art thermal battery technologies will not be able to meet future requirements that call for higher power and capacity with a smaller footprint. The principal avenue for increasing the capacity of thermal battery is to identify and develop new electrode materials that provide higher specific capacity and power performance. The overall objective of the proposed effort is to ...

Numerous operations in an increasingly congested electromagnetic spectrum, intensify demand for data at the tactical edge, and the diminishing extent of electromagnetic spectrum provisioned for the military has resulted in the need for advanced technologies to mitigate Global Positioning System (GPS) interference due to co-site interference and C4ISR. Metamagnetics proposes a powerful and adaptabl ...

Built upon the progress in Phase I period, Winchester Technologies, LLC proposes to investigate practical magnetoelectric antennas during the Phase II period for different applications. State of the art antennas suffer from three major open challenges: (1) large antenna size, (2) antenna impedance mismatch; (3) ground plane effect. This is because state of the art antennas are based on oscillating ...

There is an ever-increasing demand on low-cost high-throughput wireless front-ends. Such high-throughput front-ends support broadband data transmission (multi-Gbit/s) for a wide variety of sensors and unmanned platforms in situational awareness, monitoring, and reconnaissance. Their wideband nature also supports the deployment of broadband communication/radar combo-systems, as well as numerous eme ...

To avoid machine failure, diesel engine hardware manufacturers recommend limiting fuel contamination particles based on number and size distribution. Work performed by TARDEC has developed limits for particulate and free water contamination in fuel utilizing light obscuration particle counting; however, this approach is unable to differentiate between solid particulates, free water droplets, and a ...

Physical Sciences Inc. proposes to demonstrate and quantify a unique high performance, insensitive munition compliant, structural combustible cartridge case for ammunitions that would significantly augment the ballistic performance. This new formulation will increase the ballistic energy, impetus, and muzzle velocity, while simultaneously eliminating combustion residue and providing insensitivity ...

Physical Sciences, Inc. (PSI) will develop bi-spectral obscurant materials with tight dimensional control and properties that promote good pyrotechnic or pneumatic dissemination.In response to the Army requirement, PSI has fabricated copper disks with a diameter of 3 microns and controllable nanoscale thickness.During the proposed program PSI, will scale-up the fabrication of the copper disks, inc ...

In the near future, the Warfighter may face prolonged isolation and sustained denial of support on the battlefield, and may have no access to medical support. To become more resilient to these challenges, the Warfighter will need additional, innovative support to provide Tactical Combat Casualty Care (TCCC). Intelligent decision-support software, teleoperated trauma care systems, and fully autonom ...
