Abstract:Wide bandgap SiC power devices have the potential for reliable operations at higher junction temperatures, higher voltages, higher frequencies and thus higher power densities than what can be achieved with Si devices. These advantages enable the SiC technology-based power conversion systems (PCM) to… more
Abstract:Infrared sensors play an important role in missile defense systems, and continued improvement in their performance is critical as adversary payloads become smaller, cooler, and dimmer.

Abstract:The complexity of Atmospheric Transport and Dispersion (ATD) modeling requires physically consistent weather data evolving in both space and time. Spatially and/or temporally averaged data found in climatological products is not suitable for ATD modeling. The proposed solution for providing… more
Abstract:Atmospheric and Environmental Research, Inc. proposes to develop a prototype threat-reduction system for the dispersion of a weapons-of-mass destruction warhead in the upper atmosphere. Our system will extend current DTRA atmospheric transport and dispersion capabilities into the 20-120 km altitude… more
Abstract:DESCRIPTION (provided by applicant): Aeris therapeutics is developing a novel medical treatment for patients with advanced emphysema known as Pneumoreductive Surfactant (PRS). PRSs are inhaled drugs that increase lung recoil by safely altering the surface tension properties of native lung… more

In Phase II Aerius Photonics proposes to build and test a functional prototype high-temperature scene projector to demonstrate the fundamental operation of the SIPS. Aerius has… more
Abstract:Aerius Photonics has partnered with Raytheon Missile Systems to jointly develop a true-spectral (or hyper-spectral) projector system concept that will achieve, for the first time, the ability to project both apparent temperature and apparent emissivity over a broad temperature range and for a large… more
Abstract:We propose to demonstrate near infrared (NIR) InGaAs sensor arrays with 55% lower noise than arrays presently available to improve the sensitivity of current spectroscopy systems. The low noise performance will be enabled by the use of low-noise source follower per detector ROICs, which are also… more
Abstract:The next generation of autonomously guided munition seekers requires the development of imaging LADAR systems capable of detection through obscurants at greater ranges and with greater precision and speed while reducing system cost, weight, and power consumption. Aerius Photonics has developed an… more
Abstract:Low-thrust rocket engines (bus, vernier, divert, attitude control) operating at high altitudes can generate extended plume signatures with potential impact on forward-based missile-defense interceptor-seeker system performance. The signatures can include phenomena and features not exhibited for… more
Abstract:Nonsteady plume signatures can result from transient engine operating conditions (e.g., start-up, shut-down) or evolutionary vehicle flight conditions (acceleration, ascent). Current standard codes assume constant engine/flight conditions as for a steady engine burn in a ground static test. An… more
Abstract:Defense against modern ballistic missiles requires discrimination between lethal and nonlethal objects within a large number of nearly identical threats. This MDA SBIR Topic "Advanced Feature Extraction Algorithm" (AFEA) has the objective of developing and demonstrating an algorithm that can… more
Abstract:Optical measurements including laser velocimetry (LV), particle image velocimetry (PIV), and other similar techniques are becoming a more important part of aerodynamic testing. However their implementation into large production wind tunnels is severely hindered by difficulties with flow seeding.… more
Abstract:Special operation forces utilize C-130 aircraft that often operate in night/adverse weather, low-level, deep-penetration missions in contested or hostile environments. These low altitude missions result in higher risks to the crew and aircraft. AeroVironment proposes to leverage their current… more
Abstract:Power generation at remote locations is increasingly important to provide support for logistic and combat operations. The traditional genset driven by a diesel engine, however, is bulky, not highly efficient, and requires non-trivial maintenance. In addition, the power quality that these traditional… more

Abstract:AeroAstro proposes decomposing nitrous oxide (N2O) as an alternative propellant to existing spacecraft propellants. Decomposing N2O can be used as either a high Isp, hot-gas monopropellant or as a low Isp, cold gas for ACS thrusters. AeroAstro further proposes to use an innovative technique to… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
