Abstract:Navy ships often develop small, pinhole leaks in stainless steel fuel piping while at sea. Due to the long duration between in-dock maintenance cycles (typically one and a half to three years), temporary patches are often used to repair the leaks. The current composite patches that represent the… more

Abstract:Aircraft carriers are the backbone of the U.S. Navy"s fleet, which operates around the globe, with the sole purpose of launching and recovering aircraft to support U.S. military and peacekeeping missions. The ability to quickly and safely launch aircraft can become a key limitation for an… more
Abstract:Diode-Pumped Alkali Laser Systems (DPALS) require a uniform, steady, flowing mixture of helium and rubidium vapor at elevated pressure and temperature. Significant challenges exist because rubidium is a very reactive material. In response, our team is developing a contamination-free, all-metal,… more
Abstract:Chemical, biological, or toxin attacks in military and civilian settings are a serious and growing concern. Standard first aid for exposure to some chemical warfare agents and toxins includes the immediate administration of relevant antidotes using an autoinjector. When an attack occurs,… more
Abstract:Interfaces on existing military chemical/biological protection garments are not designed to fully eliminate macroscopic and microscopic air gaps at folds, fabric surfaces, or hook-and-loop closures, and thus do not provide a hermetic barrier against exposure. Creare proposes to develop a hermetic… more
Abstract:ABSTRACT: Current Separable Thermal Mechanical Interfaces (STMIs) found in advanced digital processing electronics are unable to efficiently remove dissipated heat, limiting performance far below their capability. The standard approach produces high contact resistance (~1.0°C-in./W) with local… more
Abstract:ABSTRACT: Accurate measurement of fastener profile relative to the aircraft skin is critical to ensure that aircraft meet operation specifications and to identify areas that require rework to meet tight manufacturing tolerances. Current measurement methods rely on mechanical dial indicators that… more
Abstract:With the continued electrification of military systems, lithium-ion (Li-ion) batteries are increasingly targeted for electrical energy storage due to their wide operating temperature range and exceptional energy density. However, Li-ion batteries operating in hostile thermal and mechanical… more
Abstract:Acoustic imaging is the preferred modality for mine detection. However, acoustic images are noisy and difficult to interpret due to acoustic clutter, the interaction of sound with the seafloor, and potential penetration of sound into the sediment with subsequent reflection. Creare proposes to… more
Abstract:Proper design of Diode-Pumped Alkali Laser Systems (DPALS) is challenging because many interrelated processes impact their performance and critical kinetic rate coefficients are not well known. In response, our team is developing a comprehensive physics-based analysis/design tool, and… more
Abstract:Future NASA space missions require advanced systems to convert thermal energy into electric power. These systems must be reliable, efficient, and lightweight. In response, we propose to develop a turbo-Brayton power converter with high efficiency and specific power. The converter will use gas… more
Abstract:Modern aircraft gas turbine engines utilize highly loaded airfoils in both the compressor and turbine to maximize performance while minimizing weight, cost, and complexity. However, high airfoil loading increases the likelihood of flow separation at lower mass flow rates. Dielectric Barrier… more
Abstract:Refueling spacecraft in space offers tremendous benefits for increased spacecraft payload capacity and reduced launch cost. However, there are several key challenges with space refueling associated with the storage and handling of liquid cryogens in space. To meet these challenges, we propose to… more
Abstract:Future human space exploration missions will require advanced life support technology that can operate across a wide range of applications and environments. Thermal control systems for space suits and spacecraft will need to meet critical requirements for water conservation and adaptability to… more
Abstract:NASA's future science missions to investigate the structure and evolution of the universe require efficient, very low temperature coolers for low noise detector systems. We propose to develop a highly efficient, lightweight Active Magnetic Regenerative Refrigeration (AMRR) system that can… more
Abstract:Future manned exploration spacecraft will need to operate in challenging thermal environments. State-of-the-art technology for active thermal control relies on sublimating water ice and venting the vapor overboard in very hot environments. This approach can lead to large loss of water and a… more
Abstract:Future manned space exploration missions will require space suits with capabilities beyond the current state of the art. Portable Life Support Systems for these future space suits face daunting challenges, since they must maintain healthy and comfortable conditions inside the suit for long-duration… more
Abstract:NASA has recognized that in future exploration and human missions to Mars, the problem of Martian dust contaminating gas processing systems and human habitats will need to be solved. The dust content of Martian atmosphere is only sparsely known, and in particular the variation over the surface and… more
Abstract:A key objective for NASA's next rover mission to Mars is the demonstration of oxygen production from atmospheric carbon dioxide. Such a technology demonstration may pave the way for a future sample return mission to the Red Planet as well as possibly a future manned mission to Mars. A… 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.
