Fires in dry bays of military aircraft present a significant hazard that must be addressed with advanced fire suppression systems. The USAF is interested in concepts that do not require power or active sensing of fire for proper operation. ADA Technologies, Inc. has been developing fine water mist fire suppression technology for the past 10 years, and proposes a solution for this problem that inco ...

The recent emergence of the Silicon Drift detector (SDD), for use in energy dispersive x-ray spectrometry (EDS), has made possible x-ray event streams with count rates as high as 1-10 Mcps. A problem with existing digital signal processing, as applied to SDDs, is the significant presence of coincidence peaks above the x-ray background. These coincidence peaks occur with amplitudes comparable to lo ...

There is a need to monitor the structural health of aerospace components operating in extreme temperatures ranges (e.g. -60 to +300C) and with high accelerations. Ideally the sensors employed for this task should be passive (i.e. not powered through batteries), permanently placed on the critical components and transmit the relevant data to a remote data processing center wirelessly.  Albido is pr ...

Polymers in space are subjected to various threats including hyperthermal oxygen atoms, UV and VUV photons, and ions.  These threats can degrade the polymer and lead to static charge accumulation.  This Phase II proposal will build on the Phase I work which demonstrated that inorganic films grown by atomic layer deposition (ALD) can protect polymers such as Kapton, Teflon and PMMA.  Al2O3 ALD f ...

Aqwest proposes to develop an advanced thermal management for cooling of electronic components using a variable conductance heat sink (VCHS) 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) ...

The DOD requires an environmentally friendly, rapid, and non-destructive method to selectively remove coatings from composite substrates.  Atmospheric Plasma Solutions Inc. (APS) has developed a cold atmospheric plasma process to accomplish this goal. Current processes for the removal of coatings from composite materials are slow, expensive, and potentially damaging to the environment. APS has de ...

This proposal outlines a novel architecture for a hyperspectral imaging projector based on liquid crystal on silicon micro-displays.

There are many applications for hyperspectral image detectors, but for the detectors to be widely accepted standardized calibration protocols must be developed. This research aims to bridge this gap through the development of a commercially available hyperspectral image projector (HIP) system. The proposed effort is to build a prototype visible HIP system to generate calibrated, realistic imagery ...

Robust altitude estimation for over-the-horizon HF radar requires a combination of advanced signal processing and high fidelity ionospheric propagation modeling. Since aircraft height is manifested in closely-spaced direct and ground-bounce multipath reflections off the target, we propose two new high resolution signal processing methods for discriminating small time delay differences from a seque ...

This work proposes to develop two critical subsystems and a rotation platform designed to enable ultracold atom inertial sensing research and development, with emphasis on rotation sensing (gyroscopes) for navigation, geolocation, mapping, and similar tasks.  The two subsystems presented here, the computer control and interface subsystem, and the integrated atom chip power source/current driver s ...
