Changes in the former Soviet Union have opened the gate for the exchange of new technology. Interest in this work has been particularly related to Thermal Electric Cooling Devices (TED's) which have an application for the Thermal Enclosure System (TES) developed by NASA. Preliminary information received by NASA/MSFC indicates that Russian TED's have higher efficiency. Based on that assumption NASA/MSFC awarded a contract to the University of Alabama in Huntsville (UAH) in order to study the...

The chronology of events and the experiences of the pilot program are outlined to describe the development of the present program. The program goals are included in order to give a focus on what the developers saw as the program drivers. Lessons learned from a pilot program were incorporated into the present program. This program is constantly learning from its past...

Nitric-oxide planar laser-induced fluorescence (NO PLIF) was used to perform velocity measurements in hypersonic flows by generating multiple tagged lines which fluoresce as they convect downstream. For each laser pulse, a single interline, progressive scan intensified CCD camera was used to obtain separate images of the initial undelayed and delayed NO molecules that had been tagged by the laser. The CCD configuration allowed for sub-microsecond acquisition of both images, resulting in...

An advanced small perturbation (ASP) potential flow theory has been developed to improve upon the classical transonic small perturbation (TSP) theories that have been used in various computer codes. These computer codes are typically used for unsteady aerodynamic and aeroelastic analyses in the nonlinear transonic flight regime. The codes exploit the simplicity of stationary Cartesian meshes with the movement or deformation of the configuration under consideration incorporated into the solution...

A mathematical model taking into account small (and constant) gravitational levels is developed for vaporization of an isolated liquid droplet suspended in a stagnant atmosphere. A goal of the present analysis is to see how small gravitational levels affect droplet gasification characteristics. Attention is focused upon determining the effects on gas-phase phenomena. The conservation equations arc normalized and nondimensionalized, and a small parameter that accounts for the effects of gravity...

The filter/smoother combination provides the most accurate means of trajectory reconstruction. Not all parameters of interest can be determined from a given flight test data set: need to check observability. A variety of ground & onboard sensors may be used; trend appears to be toward increasing reliance on onboard GPS.

A model that predicts the impact of optical radiation on visual function has been developed. The model assesses the impact of glare and glare recovery on performance by tracing the propagation of light from the source to the eye and determining the effect on visual contrast sensitivity. This capability analyzes broadband and extended sources, supports complex visual tasks, and displays a visualization of the post exposure visual recovery process. The model is composed of four components: a...

January 25, 1995: On a dark evening in the Arabian Sea off the coast of Somalia, a merchant vessel was steaming southward when its crew began to notice a strange glow in the distance. Within minutes, and for six hours thereafter, the S.S. Lima found herself cutting through waters producing a radiant white glow reminiscent of a boundless snowfield. Ten years later, scientists learning of Lima's surreal encounter sought out the date and time within an archive of low-light satellite data. The...

Research to improve electro-optic sampling led to the development of several high performance optical phase modulators. These phase modulators serve as a 'time-lens' in a series of experiments on temporal optical systems. These systems are used to generate, manipulate and measure optical pulses. Significant results have been shown in three areas. First is active optical pulse compression, where 55 ps 1.064 um pulses were compressed to 1.7 ps. Notably, laser timing jitter is reduced in this...

Airfield lighting is an essential part of the aviation business. Like the aircraft that they support, airfield lighting systems have over the years increased in size and sophistication and the financial and engineering investment in the equipment is a significant factor in the cost of an airfield.

However, the time is opportune to review the efficiency of present...

Characteristics of AgGaS2 crystal for frequency doubling of TEA CO2 10.6 micrometer laser light were investigated. When the crystal was 4. 3mm long, the maximum conversion frequency was 0.122 percent. In recent years, much progress was made in expanding the range of laser wavebands by utilizing the nonlinear effects. In the medium-infrared waveband, the CO2 laser is a relatively ideal light source and can output tens of laser spectral lines within the range 8.7 to 11.8 micrometers. With double...

Studies were performed on the precession of spin polarized electrons in a magnetic field of up to l2T. Even at densities high enough to provide gain and to see lasing, sufficient spin polarization remains for the lasing emission to alternate back and forth between right and left circular polarization as the spins precess. Thus, the vertical-cavity surface-emitting laser emission is locked to the spin precession clock, one example of coherent control.

A new method is introduced for the measurement of photochemical or photobiological reaction rates. Based on linear response theory, the method uses a randomly modulated light source rather than a pulsed one, and employs cross-correlation analysis to extract the desired kinetic information. In operation, a randomly varying light source illuminates the reaction of interest, and the resulting fluctuations in reactant (or product) concentrations are monitored. Mathematical or instrumental cross...

This thesis investigates the lens-like action of the gravitational fields of celestial bodies, which can alter the apparent intensity of more distant sources.

The issue addressed in this study is the possibility of there being a significant total change in the intensity of a source due to the combined effects of...
