Abstract:THE PERFORMANCE CAPABILITY OF EMERGENCY ESCAPE SEATS IS LIMITED AT HIGH AIRPLANE SPEEDS AND LOW ALTITUDES BY THE OCCURRENCE OF WINDBLAST INJURIES. CURRENT STATE-OF-THE-ART SEATS, AT SPEEDS OF 600 KEAS EXPOSE THE OCCUPANT TO FORCES BEYOND PHYSICALLY TOLERABLE LIMITS, DUE TO LARGE DRAG FORCES ACTING… more
Abstract:Development of combined Air-Turbo-Rocket(ATC/Scramjet component technology suitable for numerous USAF propulsion missions is proposed. Preliminary component design will focus on attaining fully throttleable boost and sustain thrust, vehicle speeds from Mach 0 to 8, and range as required. Activities… more
Abstract:CARDIAC SURGERY OFTEN INVOLVES REPLACEMENT OF THE NATURAL AORTIC VALVE, OR THE AORTIC ROOT AND ASCENDING AORTA, OR BOTH, WITH THE CORRESPONDING PROSTHESES. BLOOD FLOW THROUGH THE AORTIC VALVE IS INFLUENCED THE THE CORRESPONDING FLOW FIELD IN, AND AROUND, THE AORTIC ROOT. THERE EXISTS THE NEED FOR A… more
Abstract:Water is an attractive halon-alternative extinguishing agent for fire suppression. This SBIR proposes to develop a twin-fluid water nozzle that produces spray with a Sauter Mean Diameter less than 20 microns, and discharges water droplets at high velocities (equivalent to 500 m/s) to enhance… more
Abstract:Cavitation is believed to cause damage to tilting disk mitral mechanical heart valves (MHVs). Previous studies have indicated that this phenomenon may be dominant during MHV closure. The "squeeze-flow" field between the closing occluder and valve housing, water hammer pulse at closure and the… more
Abstract:A novel wave rotor topping cycle, which incorporates a Rich burn- Quick mix-Lean burn (RQL) combustor integrally coupled with a wave rotor, is proposed in this SBIR project. This cycle has the potential of significantly lower NOx levels than demonstrated RQL combustors, plus higher engine efficiency… more
Abstract:IN THE FIELD OF COMPUTATIONAL FLUID DYNAMICS (CFD), A MULTIZONAL APPROACH GREATLY SIMPLIFIES THE RESOLUTION OF COMPLEX GEOMETRICAL DETAILS AND THE APPLICATION OF DIFFERENT FLOW PHYSICS IN DIFFERENT ZONES OF THE FLOW DOMAIN. PREVIOUS MULTI-ZONAL PATCHED AND OVERLAPPED APPROACHES SUFFERED FROM ONE OR… more
Abstract:This innovation is a Zero-G Spacecraft Refrigeration that uses air as the refrigerant. It is an innovation because it replaces ozone - destroying and potentially toxic CFC (Chlorofluorocarbon) refrigerants with safe, inert, ordinary air. It also has the capability to recharge itself on-orbit… more
Abstract:Conventional methods for detecting traces of chemical warfare agents require: (a) collection of air, soil, or water samples, (b) analytical laboratory operations, such as chemical separation, to isolate suspected agents, and (c) laboratory analysis. Typically, this process may take days or weeks.… more
Abstract:Dynetics proposes to initiate a study to investigate the potential benefits of applying a lattice control surface technology to hypersonic vehicles as a means to improve aircraft performance and operating efficiency. Under the Phase I effert, Dynetics will develop preliminary designs of generic… more
Abstract:Dynetics proposes to initiate study to investigate the potential benefits of applying lattice control surface technology to transport aircraft as a means to substantially improve aircraft performance and operating efficiency. Under the Phase I effort, Dynetics will develop preliminary designs of… more
Abstract:Dynetics, teamed with Harris Corporation, proposes to apply our innovative spread spectrum receiver technology to produce a novel Spread Spectrum Detector for submarine electronic surveillance measure (ESM) operations. Our unique combination of hardware and algorithmic approach couples a nonlinear,… more
Abstract:Dynetics proposes to develop lattice wing control surface concepts for application to aircraft towed maneuverable bodies. Lattice control surface designs will be developed to meet towed vehicle stability and control requirements, maneuverability requirements, drag requirements and… more
Abstract:Development of the National Aerospace Plane (NASP) has exposed a serious need for materials and coatings that can survive very severe thermal environments. The heat exchanger panels for the proposed scramjet power system must withstand temperatures in excess of 2300 degrees F for significant periods… more
Abstract:This proposal is concerned with the accurate computer simulation of compressible transonic and supersonic flows. It explores the feasibility of developing a Computational Fluid Dynamics (CFD) code based on the p-version of the finite element method, which alleviates some of the inherent limitations… 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.
