Abstract:Collision Avoidance (CA) radar systems are required for compliance with the Navy"s operational requirement for Sense And Avoid (SAA) for Unmanned Aerial Systems (UASs). The Radar Airborne Collision Avoidance System (RACAS) is designed to provide CA capabilities for both Triton and Fire Scout.… more
Abstract:This effort will complement the C-RACAS transition to both Triton and Fire Scout by performing risk reduction activities addressing stressing environments and scenarios using simulation, and early data collection with prototype RACAS and C-RACAS hardware. In addition, it will address Triton"s… more
Abstract:Future experiments in nuclear (and particle) physics will require advances in detector technology in order to carry out planned measurements of QCD, electroweak interactions, studies of fundamental symmetries, understanding the spin properties of nucleons, and many other physics topics. Among the… more
Abstract:Extreme high vacuum (XHV) systems are characterized by very low gas pressure and a small outgassing rate of the system surfaces. The pumping techniques required to reach XHV conditions impede further reduction of the XHV pressure by either re-emitting chemically-stored pumped gas or allowing back… more
Abstract:The U.S. Army has a need for cheap, high quality nanosilicon powder. With similar energy density and better aging effects than nanoaluminum, silicon is an excellent candidate for use a metal nanofuel. In Phase I, Systems and Materials Research Corporation (SMRC) demonstrated a scalable method for… more
Abstract:ABSTRACT: Each fastener that is installed during the aircraft assembly requires a hole to be drilled, and those holes filled with either rivets or threaded fasteners. To add difficulty, most fasteners must have sealant applied to the hole, and interference fasteners must be inserted using an… more
Abstract:ABSTRACT: Corrosion is a serious problem affecting the longevity, safety, durability, and affordability of military and commercial aircraft. Despite strict implementation of MIL and ASTM standards for aircraft Outer Mold Line (OML) coatings, corrosion is frequently observed during maintenance… more
Abstract:Recently, the F-35 program experienced fatigue cracking in a low pressure turbine blade inside the F135 engine from recrystallization (RX). These problems cost the program time and money, strain the political capital necessary to sustain a large weapons program, and undermine the confidence of… more
Abstract:Payload stored in multiple all-up-round canisters (MACs) critical to Ohio- and Virginia-class sub missions is susceptible to damage from excessive shock and vibration loading. TRI/Austin proposes to investigate a state of the art lateral missile support system to resolve this issue. A preliminary… more
Abstract:Texas Research Institute Austin (TRI/Austin) is proposing to build an energy supply system for the Tray Ration Heating System (TRHS) that will eliminate the use of JP-8 fuel as an energy source to heat the rations. There are three operational conditions when the TRHS needs to be supplied with energy… more
Abstract:Marine forces of the future will be significantly more agile, lethal, mobile, and survivable. The current limitation on tactical wheeled vehicles is at the tire/terrain interface. Tactical wheeled vehicles need the ability to adapt to rapidly changing terrain conditions and missions by developing a… more
Abstract:ABSTRACT: TRI/Austin and the University of Texas at San Antonio have teamed to develop and demonstrate a complete set of modules and a framework for structural reliability analysis for the Air Force. These modules will be developed with a scriptable interface to enable the structural engineer to… more
Abstract:ABSTRACT: Fuel tanks for aircraft commonly utilize a hexavalent chromated polyurethane coating acting as corrosion protective secondary containment for fuel. The coating service range is from -65 to 250oF. New effective coatings free of hexavalent chromium corrosion inhibitors and offering rapid… more
Abstract:ABSTRACT: TRI/Austin proposes to develop an ultrasonic (UT) based non-destructive evaluation (NDE) system that can detect and characterize the tailored surface grain size distribution in aerospace nickel and titanium alloys. Many metals are now engineered via heat treating processes to adjust the… more
Abstract:ABSTRACT: Reliability of weapon systems after periods of storage dormancy has long been a significant concern throughout military history. The trend in missile systems over prior decades has been toward greater sophistication, complexity, and longer periods of dormancy while in transportation and… more

Abstract:High moisture permeation rates through hose wall materials are a primary failure mode for the design currently used in fat line towed arrays. These premature failures are extremely costly in terms of repair, and the loss of sensors in the towed array impacts submarine mission capability. The high… 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.
