Aerospace manufacturers are using composite structures in aircraft and they are the future of aviation. Composites reduce weight and maintenance costs. Today, many composite structures are joined together with fasteners. However to meet future design r

This proposal details an approach for coupling radio channel propagation models with models of the radio frequency electronics in a transceiver to allow simulation of bi-directional channel estimation in a wireless communication system. The proposed efforts focus on exploiting the reciprocal nature of the electromagnetic propagation to reduce overhead necessary for channel feedback or to enable es ...

SRICO proposes to develop novel and practical methods to produce a flexible, robust and highly efficient, low-loss quantum frequency conversion device based on periodically poled lithium niobate (PPLN). The focus of the program will be to optimize the device design and operating parameters to achieve less than 1.5 dB end-to-end loss while maintaining nearly 100% conversion efficiency and reducing ...

Some aerospace vehicles components require structural materials with temperature stability near or above 3000?F. Carbon-carbon (C-C) composites are prime materials for these applications because of their unique properties. Current C-C composites fabrication techniques are very expensive and time consuming. They usually require multiple infiltration and carbonization at high temperatures. Thick ...

Electrical circuit designers at Tier 2-4 suppliers to the Department of Defense (DoD) are currently using desktop computing to design their products. To improve the circuit design in the DoD supply chain, designers will need to be able to analyze their circuits with High Performance Computing resources. Designers seeking to innovate their circuits must have access to HPC facilities that maintain c ...

In order to maintain our nation’s technological superiority on air, sea and land, we must respond quicker to emerging threats and reduce the cost of major sensing platforms. Every DoD platform developed nowadays contains at least one sensor, whether it be RF, EO/IR, or acoustic. In fact, in a lot of recent developments, the platform is built around the sensor and exists only to support the senso ...

A significant amount of personal injury and property damage as well as lost productivity could be avoided by speeding up the body’s adjustment cycle to new circadian schedules or re-synchronizing body schedules that have slipped or advanced. For the military, this problem is especially acute because the warfighters’ duties include dangerous equipment and a need for 24-hour operational readine ...

Within harsh environment areas, Naval vessels require illumination. Incandescent based Symbol 48.2 explosion-proof fixtures are rated to operate in these spaces but are inefficient, resulting in unsafe fixture surface temperatures and unnecessarily high energy consumption. Under such extreme operating conditions, the lamps in the fixtures fail frequently, leading to high maintenance costs. Prod ...

This program proposes to demonstrate an ultra-low power design methodology and circuits for digital logic employing advanced dynamic voltage scaling (DVS) for asynchronous NULL Convention Logic (NCL) circuits operating in sub-threshold to super-threshold voltage regimes. The power supply voltages of logic block partitions will be independently set by on-chip voltage controllers based on the data p ...

This Small Business Innovation Research Phase II project develops novel materials processing and device design that extract the maximum possible performance out of the lithium niobate electro-optic material. The novel modulator device incorporates reconfigurable quasi-phase matching (RQPM) to produce an arbitrary RF bandpass response. The Phase I effort has laid a firm foundation for the creation ...
