OVER THE PAST SEVERAL YEARS, UNDER GOVERNMENT AND COMMERCIALSUPPORT, CONTINUUM DYNAMICS, INC. HAS MADE SIGNIFICANT PROGRESS IN COMPUTING THE UNSTEADY WAKES OF FIXED- AND ROTARY-WING AIRCRAFT. THIS PROGRESS, FOR THE MOST PART, RESULTED FROM THE SUCCESSFUL DEVELOPMENT OF THE BASIC CURVEDVORTEX ELEMENT AS A FUNDAMENTAL WAKE ELEMENT BUILDING BLOCK AND A NOVEL GENERALIZED VORTICITY CONTOUR REPRESENTATI ...

THE GOAL OF THIS RESEARCH IS TO PRODUCE A NEW, REAL GAS, THREE-DIMENSIONAL, PARABOLIZED NAVIER-STOKES (PNS) CODE WHICH IS MORE ROBUST, MORE ACCURATE, AND EASIER TO USE THAN THOSE PRESENTLY IN EXISTENCE. MOST "CURRENT DAY" PNS CODES (INCLUDING THE AFWAL PNS CODE) ARE BASED ON THE NONITERATIVE, IMPLICIT BEAM-WARMING FINITE-DIFFERENCE SCHEME. UNFORTUNATELY, CODES OF THIS TYPE HAVE PROVEN TO BEUNRELIA ...

SPECTRAL MEASUREMENTS OVER THE VISIBLE/NEAR-INFRARED 0.5-1.7 MICRON RANGE CANNOT BE DONE AT PRESENT WITH A SINGLEDETECTOR. TWO SEPARATE DETECTORS (SILICON FOR 0.5-1.1 MICRONS AND GERMANIUM FOR 1.0-1.7 MICRONS) MUST PRESENTLY BE USED IN ORDER TO COVER THE ENTIRE SPECTRAL RANGE. THIS COMPLICATES MEASUREMENT PROCEDURES AND ADDS COST AND EXTRA COMPONENTS TO THE SYSTEM. WE PROPOSE TO DEVELOP A LARGE-AR ...

WE PROPOSE TO DEVELOP A INGAASP/INP DOUBLE HETROSTRUCTURE LASER THAT WILL OPERATE WITH A WAVELENGTH OF 1.08 MICRON. THE CW LASER WILL BE TUNABLE TO PRODUCE LIGHT EQUIVALENT TO THE HELIUM SPECTRAL LINES AT 1.083 MICRON. THIS LASER CAN BE USED AS AN OPTICAL PUMPING SOURCE FOR HE3 AND HE4 ATOMS USED IN SPACE MAGNETOMETERS. CONTINUOUS OUTPUT POWER OF 10MW IS THE DESIGN GOAL.

THE MICROGRAVITY ENVIRONMENT OF EARTH ORBIT HAS THE POTENTIAL TO IMPROVE THE QUALITY AND INCREASE THE YIELD OF MATERIALS GROWN BY CHEMICAL VAPOR DEPOSITION (CVD). THE DEVELOPMENT OF CVD IN SPACE WOULD BENEFIT GREATLY FROM THE CAPABILITY TO PREDICT THE IMPORTANT PROCESS HEHAVIOR, ESPECIALLY UNDER THE INFLUENCE OF VARYING GRAVITY FIELDS. THIS CAPABILITY WOULD NOT ONLY FOSTER COMPARISON OF MICROGRAVI ...

TWO-PHASE THERMAL TRANSPORT LOOPS OFFER SIGNIFICANT WEIGHT AND PERFORMANCE ADVANTAGES OVER CONVENTIONAL SINGLE-PHASE SPACECRAFT THERMAL MANAGEMENT SYSTEMS. KEY COMPONENTS IN TWO-PHASE THERMAL MANAGEMENT SYSTEMS ARE THE CONDENSING AND EVAPORATING HEAT EXCHANGERS TO COUPLE THE LOADS TO THE TWO-PHASE THERMAL BUS, AND TO TRANSFER HEAT BETWEEN THE THERMAL BUS AND THE SPACECRAFT RADIATOR. THE MAIN REQUI ...

Space structures that are ultra-lightweight, and have gas barrier property, space durability, radiation resistance, EMI shielding, and high impact resistance are desirable to improve the reliability and provide a safe resting environment for astronauts and electronic equipment housing and protection. Some of the components currently in use such as stations or habitats use double-wall thick films w ...

Ridgetop's role is to develop electronic prognostics for sensing power systems in support of NASA/Ames ADAPT testbed. The prognostic enabled power systems from Ridgetop are to be integrated into NASA's Advanced Diagnostics and Prognostics Testbed (ADAPT) and later used in the Crew Exploration Vehicle (CEV). Prognostics will provide power supply "state of health", remaining useful life (RUL) and ...

Cornerstone Research Group Inc. (CRG) will develop new shape memory polymer (SMP) deployment mechanisms for actuating thermal protection system (TPS) panels to create a deployable, large surface area aeroshell. This innovation will exploit Veriflex(R) -- CRG's high-performance SMP material -- to create a low-mass actuation system for a deployable aeroshell design. Veriflex(R)-based mechanisms wi ...

ZIN Technologies, Inc. is developing a novel Miniature Treadmill with resistive exercise capability for use in spaceflight exercise countermeasures and broad terrestrial therapeutic applications. The treadmill offers excellent periodic impact exercise to stimulate bone remodeling and cardiovascular activity as well as an added component of resistive exercise to encourage all-body muscle maintenanc ...
