High temperature permanent magnet materials play an important role in NASA's space missions in electric propulsion, energy generation and storage and other applications. We propose to devise accelerated testing methods to test and predict the service life of SmCo based ultra high temperature permanent magnets in a high vacuum environment at high temperatures in excess of 400 degrees C. The propo ...

Many hazardous gases that NASA needs to monitor on and around space vehicles during launch could be detected using mass spectrometers that need operate over only a limited mass range. But, stringent requirements of low weight and low power operation, plus the ability to tolerate high G-forces and excessive vibration prevent the ready adaptation of existing, commercial mass spectrometers to these a ...

The prediction, identification and notification of spacecraft fires is critical in assuring the safety of manned space missions. Absent the effects of buoyancy in space, the chemical and fluid dynamic phenomena that govern the ignition, spread and extinction of fires are far different than those on Earth. Our understanding and predictive capabilities depend on detailed models that must be versatil ...

Several significant potential infrared applications of tunable Fabry-Perot interferometers are not presently possible because of the unavailability of a Fabry-Perot that can be tuned at cryogenic temperatures. For operation in the far infrared (8-12 micron) region of the electromagnetic spectrum, optics must be kept at cryogenic temperature. At present, such devices are not commercially available ...

Large stroke and high precision electroactive single crystal and polymer actuators are desired for cryogenic passive optics such as Fabry-Perot Interferometer (FPI) and Fourier Transform Spectrometer (FTS) in NASA remote sensing missions. The results of the Phase I program have successfully demonstrated the feasibility of using electroactive single crystal and polymer actuator concepts for large ...

Diamond Data Systems (DDS) proposes the development of a new advanced architecture, algorithms and software to support the end-to-end processing of LIDAR data to derive useful information products such as Digital Elevation Models (DEM). The approach is innovative in three ways. First, it proposes a complete end-to-end system instead of a solution that addresses only a single step of the complex ...

The Laser-Engineered-Net-Shaping (LENSTM) process uses a laser to create a molten pool on the surface of a substrate in which metal powder is then injected to increase the volume of the pool. The laser spot is selectively scanned to additively build up the required material in the desired shape. In a sequential fashion, each cross-sectional layer of the object is taken from a 3-D CAD file and depo ...

A very promising approach to a significant reduction of the mass of the gasdynamic mirror (GDM) fusion propulsion system is proposed. It makes use of field-reversal techniques whereby a rotating magnetic field is employed to induce an azimuthal current in the plasma, which in turn gives rise to the desired magnetic field at an appropriate plasma radius in the mirror region. This has the effect of ...
