Award Data

Current state-of-the-art, high voltage, pulsed power systems designed to drive high power microwave (HPM) sources utilize Marx generator designs. The high voltage insulation of these devices has been traditionally based on either high dielectric strength oil or sulfur hexafluoride (SF6). The dielectric strength of the insulating medium determines the minimum size of the tank enclosure of the Mar ...

Aqwest proposes to develop an advanced thermal management for cooling of electronic components using an active heat sink (AHS) offering unparalleled capabilities in high-heat flux handling and temperature control. The project will produce a cooling system with the following benefits to wide band gap amplifiers and high-power laser diodes (HPLD): 1) Heat flux handling > 1200 W/cm2 2) Easily scalabl ...

Space surveillance or reconnaissance is that component of space situational awareness focused on the detection of resident space objects (RSOs) and the use of multisource data including available radar and electro-optical data to track and identify space objects. Our proposed program aims to develop modern and robust approaches to tracking RSOs through the use of advanced nonlinear estimation (fi ...

In the Phase II program we will demonstrate a breadboard device of an innovative all-fiber infrared (IR) laser operating at selectable wavelengths in the 1.5 to 12 micron spectral region based on Stimulated Raman Scattering of hydrogen gas in an IR hollow-core photonic band-gap (PBG) fiber. The Raman laser is pumped by commercially available fiber laser at near-infrared wavelength. Its wavelength ...

Thermal barrier coatings have been widely used to provide thermal protection to superalloy components in gas turbine engines. After certain amount of service time, the coating experiences a reduction in thickness by processes such as wear, erosion and foreign/domestic object damage. When the thickness decreases below a critical value, the thermal barrier effect provided by the coating is no longer ...

Developments in micro/nano technologies are leading the way to a new fleet of micro air vehicle (MAV) airframes. However, the unavoidable and ultimately the mission-limiting issue for all of these new systems will be on-board power. The lightest-weight current lithium-polymer batteries don’t provide sufficient energy densities and impose a variety of operational limitations that are unacceptab ...

An expedited and economical nanostructural sampling and analysis of semiconductor devices will be crucial to accelerated product development and rapid introduction of these technologies to the market with a higher quality at a lower cost. The proposed effort aims to carry out the next phase of development activities, geared toward realization of the above objective. We successfully demonstrated ...

The United States has expended tremendous amounts of time and effort in maintaining the capability of our most critical space assets with a high degree of fidelity despite a wide range of possible occurrences. For the most part, however, the current threat model is largely natural. It has become increasingly important to improve our asset protection methodologies against malicious, intentional a ...

The space community has, over the course of the past several years, performed research into Space Situation Awareness (SSA). As SSA and reasoning technologies advance, SSA has become a central factor in identifying and responding to space threats. The ISS Team proposes to advance SSA capabilities through the development of predictive SSA technologies. The objective of the proposed Space Situati ...
