Abstract:TDA Research, Inc. is developing a compact, low power, Next-Generation Exercise Device (NGRED) that can generate any force between 5 and 600 lbf. We use a closed loop control system and a servo motor to smoothly and accurately simulate the gravitational and inertial loads of lifting a weight on… more
Abstract:The increasing frequency of International Space Station (ISS) egress operations results in chemical contamination of the spacecraft environment. Among the most important contaminants are propellant residues (such as hydrazine) and their decomposition by-products, as well as coolants such as ammonia… more
Abstract:A spacecraft thermal control system must keep the vehicle, avionics and atmosphere (if crewed) within a defined temperature range. Since water is non-toxic and good for heat transport, it is typically used as the coolant that circulates within the crew cabin boundary. This loop then interfaces with… more
Abstract:TDA Research, Inc. and the University of Colorado at Boulder will team together to develop a responsive sequestration coating for chemical warfare agents. The coating will be easily applied to surfaces where it will cover and contain chemical warfare agents on vehicles or other hardware known or… more
Abstract:Approximately 5-6% of military injuries involve some form of major peripheral nerve injury with little chance of spontaneous healing. Currently these injuries lead to major impairment of voluntary muscle function in the limbs and extremities, making tasks of walking, reaching, grasping, etc. very… more
Abstract:TDA Research, Inc. (TDA) proposes new materials with exceptionally high absorbance in the ultraviolet that are designed to be used as obscurants to defeat the dual-band tracking systems used in modern missile systems. The Navy seeks advanced obscurant materials that will protect military assets such… more
Abstract:Decontamination of chemical and biological threats demands a very reactive solution. It is ideal to generate the decontaminants on-site: the activated decontaminant is highly reactive and quickly destroys chemical and biological warfare agents; prior to activation the ingredients can be safely… more
Abstract:It is challenging to detect CBRN weapons production facilities that are hidden in residential and industrial neighborhoods. Once the weapons are manufactured, they will be sealed and removed from the site of production, so developing techniques to reveal the presence of the weapons will likely be… more
Abstract:Advances in biodegradable materials have allowed the development of a variety of resorbable medical devices that do no need to be removed at the end of their service because they degrade within the body into not toxic by-products. However, devices that contain electronic components are still nearly… more
Abstract:Due to its favorable combustion properties, aluminum is the material of choice in metalized nanoparticle formulations for energetic materials; however, the full potential of aluminum nanoparticles has not been realized due to the presence of a nascent oxide layer (Al2O3) that surrounds the… more
Abstract:Marine-grade aluminum alloys (5XXX-series) are increasingly being used in naval combatants because they have high strength and high corrosion resistance. In order to decrease weight, these corrosion resistant marine-grade aluminum alloys are not painted with the conventional primer and low solar… more
Abstract:DESCRIPTION (provided by applicant): The principal aim of this project is to obtain proof-of-concept for a new nanotechnology-based sensor material for rapid and sensitive fluorescence detection of polycyclic aromatic hydrocarbons (PAHs) and polychloro biphenyls (PCBs). Simple, cheap and safe… more
Abstract:The respiration of fresh fruits and vegetables (FF & amp;V) converts oxygen from the surrounding air into carbon dioxide, moisture and ethylene. While ethylene is used under controlled conditions as a ripening agent, the presence of even small amounts of ethylene gas in shipping and storage… more
Abstract:This project will develop a catalytic process to manufacture a new renewable and degradable bio-plastic that could be used to replace polyethylene in many applications, including those that constitute a large part of land and ocean litter such as bags, food packaging and disposable tableware.
Abstract:The production of turpentine in the U.S. exceeded 301,000 tons in 2004 (Romney 2004) and the production of resin acids exceeded 800,000 ton in 2003 (Romney 2004), which also includes the production from directly tapping trees (e.g., gum turpentine, gum rosin). There is growing demand for… more
Abstract:ABSTRACT: The surfaces of rocket engines are exposed to high pressure combustion products at temperatures up to 6000°F. Regenerative cooling can cause coke to form on the heat exchanger surfaces and the intention to reuse engines creates the potential for excessive coke accumulation, reduced… more
Abstract:ABSTRACT: The development of weapons that can travel at hypersonic speeds is becoming a high priority to the US Air Force. Continued development of these vehicles relies on the ability to cool the combustor using the fuel. The cooling capacity of kerosene-based fuels is low even with endothermic… more
Abstract:Spacecraft operations demand a high level of responsiveness in dynamic environments. During operations, it is possible for unexpected events and anomalies to disrupt the mission schedule, and in the case of critical faults, even threaten the health and safety of the spacecraft. Historically, it has… more
Abstract:Reliable knowledge of soil moisture is required for numerous Army and civilian applications including mobility assessments, flood forecasting, agricultural management, erosion mitigation, and control of vector-borne diseases. Soil moisture cannot be measured at the resolution that is required for… more
Abstract:Aircraft equipped with On-Board Oxygen Generating Systems (OBOGS) selectively filter nitrogen and other gaseous contaminants in air from the aircraft's engine to provide the aircrew with an oxygen enriched breathing gas. Under suboptimal operating conditions, toxic byproducts can breach the… more
Abstract:Advancements are needed to improve and optimize the performance of existing and future concentrating solar power (CSP) plants by developing and improving the reliability of advanced instrumentation. A need has been identified for improved pressure, temperature, flow and level sensors for existing… more
Abstract:There is a need for condition monitoring sensors capable of function in the harshest environments associated with advanced power systems that will: directly contribute to improving system control, protect capital equipment investment, and promote safety through prevention of catastrophic… more
Abstract:Sporian proposes to develop a wireless sensor suite for rotorcraft Generator Control Unit (GCU) and Main Power Relay (MPR) health monitoring. This sensor suite will monitor the GCU for changes in component characteristics (e.g. resistance of relay contacts), temperature, vibration extremes, voltage… more
Abstract:Sporian Microsystems Inc. has spent the last several years developing polymer derived SiCN sensor and associated packaging technology for application temperatures up to 1350 & #176;C, and demonstrated them in the combustion environments of a range of commercial burner rigs and aerospace turbine… more
Abstract:ABSTRACT: There has been a strong desire in the turbine engine and thermal protection systems communities to measure surface parameters (such as temperature/pressure) in tight spaces within the engine system using conformal sensors. This type of sensor, prescribed in areas such as turbine 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.
