ABSTRACT: An exhaust plume is a primary observable to warning sensors designed to protect low flying aircraft from MANPADS and other hostile threats such as RPG's and small arms fire with tracers. The design of current and future warning sensors and countermeasures need a complete characterization of this observable. This effort is designed to transition image morphing technology, tailored ...

ABSTRACT: The proposed program will provide three important products to the space electronics community: [A] An extremely rad-hard (estimated>3Mrad) high isolation and processor-free converter that can provide an (unregulated) intermediary voltage that can supply 6V/20V at 25W/40W respectively. [B] An extremely rad hard high isolation and processor-free converter that can provide an unregulated ...

ABSTRACT: Cavitation which leads to head falloff and feed system instabilities are a constant source of problems for the low net positive suction head (NPSH) pumps that are needed for advanced liquid rocket engines. Head falloff limits the pumps capability to deliver propellant at the required pressure and cavitation induced instabilities are a significant source of structural failures in rocket ...

ABSTRACT: A new thermal response module will be developed for the XFdtd electromagnetic full-wave solver, building on versions that were available in prior releases of the software to incorporate accuracy and new features from the latest approaches in the technical literature. A user-friendly graphical user interface will also be developed in XFdtd 7 for setting up and executing simulations and ...

ABSTRACT: A need exists for a reliable, low cost radiation-hardened digital memory in aerospace and defense applications and in long-life, high-speed memory for terrestrial and commercial applications. Present offerings can accomplish the objective, but only at the expense of performance, power, size, and weight with device redundancy and shielding. Recent focus on Graphene and its capabilities ...

This project aims to increase the reliability of radio frequency (RF) devices used in accelerator facilities by reducing/eliminating corrosion and erosion produced from the high purity de-ionized water cooling systems. Although metal interconnects are required for electrical and thermal performance, they susceptible to two major failure mechanisms, corrosion and erosion. Currently RF lo ...

Aging and obsolescence issues have recently led to problems with the rod control systems of existing pressurized water reactors. These issues, along with plans for plant life extension, have prompted the industry to actively seek viable options to monitor the health of these systems in order to ensure reliable plant operation for decades to come. This proposed work offers a comprehensive research ...

The variation between peak and off-peak electricity demand fluctuates up to 70 percent over the course of a 24 hour cycle. This degree of variability is a driver for costly inefficiencies within the power gridto prevent blackouts and meet customer demandas well as power sell offs to consume excess generation available during off-peak hours. Projections estimate the power demand to double by 2050 r ...

Accelerators used for nuclear-physics research require megawatts of radio-frequency energy. They currently employ vacuum-tube power amplifiers or conventional solid-state amplifiers that are inefficient and therefore consume a great deal of prime power. Many other applications including semiconductor processing, cellular-telephone base station transmitters and military communication systems simila ...
