These types of functions are in some ways suited to a surgical robot, offering the potential for teleoperation or… more
Abstract:Dynamic Structures and Materials, LLC (DSM) proposes a novel piezoelectric ceramic motor actuator for actuating flight control surfaces such as canards in mortars and gun launched munitions. The proposed miniature piezoelectric ceramic actuation technology is based on a "inertial" vibration motor… more
Abstract:An innovate re-entry power system is proposed for development which collects the re-entry energy for a vehicle/module entering the atmosphere for LEO using an MHD power generator that is configured on the exterior surface of the vehicle nose to utilize the heated air sheath as the plasma for… more
Abstract:This Small Business Technology Transfer (STTR) Phase I project seeks to establish the feasibility of an entirely new class of liquid electrolyte separator for Li ion batteries that has a built-in reversible thermal shutdown mechanism. With increasing use of Li ion batteries, safety is of particular… more
Abstract:The UCDS process uses a rigorous theoretical model to understand the dynamics of combustion instability. In addition to predicting the amplitude of pressure oscillations, UCDS provides clear insight into why a propulsion device oscillates. To enhance and optimize UCDS for missile defense… more
Abstract:The Universal Combustion Device Stability (UCDS) Process is the culmination of more than 40 years of research and provides the means to understand the complex dynamics and processes inside any chemical propulsion system, including liquid rockets, solid rockets, hybrid rockets, turbojet combustors… more
Abstract:A recent breakthrough in combustion stability analysis (UCDS) offers the potential to predict the combustion stability of a scramjet. This capability is very important due to the extreme scramjet operational environment, which makes cut-and-try development approaches impractical. With UCDS, it will… more
Abstract:To ensure the success of mid-scale scramjet development efforts, it will be essential to include the effects of chamber pressure oscillations (i.e. instability) on the engine heat load. This will require the inclusion of both the oscillatory heat load that accompanies the pressure oscillations and… 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.
