Researchers have determined that lunar soil contains approximately 43% oxygen in the lunar soil oxides, which could be extracted to provide breathable oxygen for consumption by astronauts. The proposed program will develop a solar receiver for the hydrogen reduction process that uses sodium heat pipes in the 1050oC temperature range. The heat pipe solar receiver is accepts the non-uniform solar ...

Long-term Lunar and Martian systems present challenges to thermal systems, including changes in thermal load, and large changes in the thermal environment between day and night. The innovation in the program is the development of a variable conductance heat pipe (VCHP) that passively accommodates the changing thermal load and environment. This allows the heat pipe evaporators (and any attached h ...

PERMANENT MAGNETS BASED ON ND2FE14B AND PR2FE14B EXHIBIT VERY HIGH MAGNETIC ENERGY PRODUCTS AT ROOM TEMPERATURE. THESE COMPOSITIONS HAVE BEEN SLIGHTLY MODIFIED BY ADDING COBALT AND ALUMINUM TO EXTEND THEIR UTILITY OVER A WIDE TEMPERATURE RANGE. FOR EXAMPLE, A PR-FE-B MAGNET RECENTLY PRODUCED IN OUR LABORATORY EXHIBITED AN ENERGY PRODUCT OF 50 MGOE AT 77 K. WE HAVE ALSO DEVELOPED PR-FE-CO-A1-B MAGN ...

IN THE SPACE ENVIRONMENT, MANY TASKS MUST BE PERFORMED THROUGH TELEOPERATION OF REMOTELY CONTROLLED DEVICES. CURRENTLY, OPERATORS TRANSMIT CONTROL COMMANDS TO REMOTE MANIPULATORS WHILE VIEWING THE WORLD ON CONVENTIONAL TV MONITORS. THE MONITORS DO NOT PROVIDE A FEELING OF ON-SCENE PRESENCE BUT INSTEAD PRODUCE A PERCEPTION OF REMOTENESS BECAUSE OF THE LOSS OF DEPTH INFORMATION COMBINED WITH REDUCED ...

AURORA OPTICS PROPOSES TO DEVELOP AND DEMONSTRATE A FIBER-OPTIC FLUID FLOW SENSOR USING THE PHOTOELASTIC EFFECT TO DIRECTLY MODULATE THE AMPLITUDE OF A BEAM OF LIGHT. BY MOUNTING A PHOTOELASTIC PRESSURE SENSOR ON THE SIDE OF A VORTEX-SWIRL FLOW HOUSING, PRESSURE PULSES MAY BE SENSED. THE PRESSURE PULSE FREQUENCY IS A LINEAR FUNCTION OF FLOW RATE IN A VORTEX SWIRL METER. THE PRESSURE SENSOR ITSELF ...

The goal of the proposed work is to create new ways to manage, visualize, and share data produced by multiple software analysis tools, and to create a framework for integrating diversely-sourced analysis tools into software practices, across the lifecycle, in a way that improves both reliability and productivity. Software analysis tools are used by software programmers, analysts, and managers to ...

THE NEED EXISTS FOR AIRCRAFT PROPULSION ENGINES WHICH CAN OPERATE EFFICIENTLY AT FLIGHT SPEEDS ABOVE MACH 3. AN INNOVATIVE HYPERSONIC CRUISE ENGINE IS PROPOSED, CALLED THE RAMFAN, WHICH INCORPORATES BOTH A RAMJET AND A FAN. PROJECT OBJECTIVES ARE: TO ESTABLISH THE CURRENT STATUS OF CRITICAL RAMFAN TECHNOLOGIES, TO DETERMINE THE PERFORMANCE POTENTIAL OF THE RAMFAN, AND TO ASSESS THE MERITS OF THE R ...

Single crystal piezoelectric deformable mirrors with high actuator density, fine pitch, large stroke and no floating wires will be developed for future NASA science and communications applications. Single crystal piezoelectric DMs share the fine pitch with co-fired electrostrictive or ceramic piezoelectric DMs and MEMS DMs, but with large stroke at relatively low voltages (< 150 V) and with a broa ...
