This multiphase project develops higher heat resistant materials for use in face shields of self-contained breathing apparatuses (SCBAs) and brings them to commercial markets. Key findings of the Phase I work are that polyethersulfone (PES) is a promising replacement for polycarbonate (PC) with respect to thermal and optical properties. However, PES has considerably lower mechanical impact strengt ...

Hyperspectral remote sensing in the microwave offers the opportunity to substantially improve the atmospheric information provided to numerical weather prediction data assimilation systems, enabling advancements in forecast skill. This Phase I project proposes a numerical study leading to selection of optimal channels for a space borne hyperspectral sensor. Based on the recommendations from a n ...

Nanosatellites are receiving increased interest since they are proving reliable for surveillance, communication and other space missions. Also, the possibility of launching "constellations" of them offers unique capabilities for low-cost experimentation, sensing and communications in space. In comparison to larger spacecraft, their development time and costs have reduced and their launch costs a ...

A spacecraft thermal control system must keep the cabin (both air and its structure if manned) and electronic equipment within a narrow temperature range even though the environment may vary from very cold to warmer than room temperature. Since water is safe to use and an excellent coolant (other than its high freeze point and volumetric expansion during freeze), a water coolant loop often is use ...

Frequency stabilized lasers are essential subsystems; as flywheel oscillators in optical atomic clocks, as well as in many sensing and measurement systems. In optical atomic clocks, Allan Deviations

ABSTRACT: Tech-X Corporation in partnership with the University of Washington will develop a commercial tool for modeling multi-fluid and single fluid plasmas including the ability to model problems using unstructured grids. An oracle will be developed to inform the user of the validity of plasma models in the regime of a given simulation. Algorithms developed at the University of Washington (i ...

ABSTRACT: Microscopy is a critical enabling technology for advancing our understanding of nature. Imaging nanoscale objects with light in the extreme ultraviolet (EUV) and soft x-ray regions of the spectrum has advantages over visible light for resolution, elemental specificity, and imaging internal structures. Coherent diffractive imaging (CDI) has been developed as a tool to get around the li ...

ABSTRACT: The need for improved routing to support ad-hoc satellite communications is apparent and protocol research has been performed to date which would greatly impact future DoD systems. The Internet Router in Space (IRIS)technology developed by SEAKR and Cisco has provided an advantageous mixture of space-qualified capability and commercial device performance and provides a strong basis upo ...

ABSTRACT: Strongly coupled plasmas are important to the Air Force for emerging applications including plasma opening switches, quantum information systems, ionospheric plasmas related to atmospheric explosions, and micro-plasma devices. Traditionally, researchers have used modeling and simulation with great success to help understand plasma behavior. However, present modeling tools usually assu ...

ABSTRACT: Satellite drag is the leading cause of orbit prediction error in low earth orbit. Modeling of this drag force and its variability is critical to accurate orbit determination and prediction. One of the leading contributing factors to error in drag prediction is thermospheric neutral density variability. Operational models up until the present time have been empirical, with inputs includ ...
