Abstract:THE ABILITY TO LIFT HEAT FROM A SELECTED PORTION OF THE SPACECRAFT IS REQUIRED IN A NUMBER OF THERMAL MANAGEMENT TASKS FOR SPACED BASED SENSOR AND WEAPON SYSTEMS. THE PROPOSED EFFORT WILL DEVELOP THE THEORETICAL AND ANALYTICAL FRAMEWORK TO ASSESS THE UTILITY AND FEASIBILITY OF A HOT PISTON PULSE… more
Abstract:Three areas of research on low cost, reliable, folding aero surfaces will be conducted. First, different types of fin deployment and flight control actuators will be examined. These include conventional fin actuators, shape-memory-alloy, piezoelectric, magnetostrictive, and electrostrictive… more
Abstract:IN GENERAL, PROTEINS FOLD WITH HYDROPHOBIC RESIDUES BURIED, AWAY FROM WATER. REVERSIBLE PROTEIN FOLDING DUE TO HYDROPHOBIC INTERACTIONS RESULTS FROM INVERSE TEMPERATURE TRANSITIONS WHERE FOLDING OCCURS ON RAISING THE TEMPERATURE. SINCE WARM-BLOODED ANIMALS PROVIDE AN INFINITE HEAT RESERVOIR, THE… more
Abstract:Of the several protein elastomers - elastin, resilin, abduction, titin and twitchin- the elastomer with the greatest demonstrated durability is elastin. It is perhaps no coincidence that elasting is also most hydrophobic, as durability and hydrophobicity may be coupled. Also, greater hydrophobicity… more
Abstract:The objective of this proposal is the development of degradable, transducible, biocompatible, elastomeric matrices to function as drug delivery systems. Despite continuing interest in the development of polymers, both synthetic and natural, (over a 25-year period), there is yet a need for suitable… more
Abstract:The objective is to modify a currently available, synthetic polypeptide polymer to prevent the adhesions and fibrovascular scarring which can follow strabismus and retinal detachment surgery. Such scarring often produces significant restriction to eye movement and malposition of the eyes. The… more
Abstract:The turbojet engine starter system utilizes the pressure of the solid propellant boost motor to pressurize a fluid contained in a bladder tank. The increase in fluid pressure ruptures a diaphragm containment seal allowing the fluid to flow through a boost motor/heat exchanger where the high pressure… more
Abstract:THE OBJECTIVE OF THIS PROJECT IS TO DETERMINE THE FEASIBILITY OF DEVELOPING CLASS 28 IO KW (12.5 EVA) AND 30 KW (37.5 KVA) AUXILIARY POWER UNITS THAT ARE LIGHTER THAN PRESENT M D INVENTORY WITH 120 VOLT A.C. - 3% AT 60 HZ AT A .8 POWER FACTOR THAT HAVE MAXIMUM NOISE LEVELS OF 7SDB (A) AT ONE METER… more
Abstract:THE EXISTING METHODOLOGY OF DESIGN AND FABRICATION OF SEMICONDUCTOR MANUFACTURING EQUIPMENT IS AN EXPENSIVE AND TIME CONSUMING PROCESS. TO KEEP PACE WITH THE RAPIDLY ADVANCING SEMICONDUCTOR INDUSTRY, IT IS NECESSARY TO DEVELOP A COMPUTER BASED ENVIRONMENT TO QUICKLY SIMULATE THE FEATURES OF THE… more
Abstract:ADVANCED ENGINE TECHNOLOGY AND HYPERSONIC FLIGHT SPEEDS OF FUTURE MILITARY AIRCRAFTS PLACE INCREASING HEAT LOAD ON JET FUELS. THE INCREASE IN HEAT LOAD PUSH THE OPERATION OF FUELS INTO THEIR SUPERCRITICAL REGIME. THE PERFORMANCE OF FUTURE AIRCRAFT WILL BE SERIOUSLY LIMITED IF FUELS CANNOT BE… more
Abstract:For sustained high speed flight (Mach 3-6), recent studies have shown that endothermic fuels are required to cool aircraft systems. Such a cooling system would deliver fuel to the ramburner in varying amounts of liquid and gaseous phases. This project proposes to experimentally investigate and… more
Abstract:The proposed Inlet Protection System (IPS) concept includes advanced T800 features and potential implementation of Electrostatic Particle Separation (EPS) technology. It is retrofitable into existing installations as well as integratable into future APU/SPU engines. CFDRC proposes an… more
Abstract:PRINCIPAL INVESTIGATOR: Fox, Jeffrey AWARDEE ORGANIZATION: Medical Opportunities, Inc. 2123 Jenkintown Road Glenside, PA 19038 TELEPHONE NUMBER: (215) 887-4640 AWARDEE NUMBER: 97-P-08002/3 The project seeks to develop an electronic communications system (Provider Path) which will allow medical… more
Abstract:DYNETICS PROPOSES A NOVEL PROCESSING TECHNIQUE FOR INCREASING THE RANGE RESOLUTION CAPABILITY OF A LARGE CLASS OF RADARS. THIS TECHNIQUE, LINEAR FREQUENCY MODULATION ENVELOPE PROCESSING (LFMEP), ALLOWS RANGE RESOLUTION FOR LFM SIGNALS THAT IS NOT LIMITED IN THE USUAL WAY BY THE WAVEFORM'S BANDWIDTH.… more
Abstract:Among the most demanding problems for millimeter wave (MMW) radar guided missiles such as that being developed for the Brilliant Antitank (BAT) program is the detection and classification of stationary ground targets in clutter rich environments for autonomous acquisition and terminal homing. This… 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.
