This dissertation describes a multi-mission investigation of the high mass X-ray binary pulsar Centaurus X-3. Cen X-3 was observed with the Broad Band X-Ray Telescope (BBXRT) in December 1990. This was the first high-resolution solid state X-ray spectrometer to cover the iron K fluorescence region. The Fe K emission feature was resolved into two components for the first time. A broad 6.7 keV feature was found to be a blend of lines from Fe XXI-Fe XXVI with energies ranging from 6.6 to 6.9 keV...

This report presents an overview of the latest scientific consensus understanding of the effect of aviation emissions on the atmosphere for both local air quality and climate change in order to provide a contextual framework for raising future questions to help assess the environmental benefits of technology goals. Although studies of the two issues share a common framework (of quantifying the emissions, the change in concentrations in the atmosphere, and the environmental impacts), the...

A three-dimensional subsonic aerodynamic panel code (VSAERO) was used to predict the effects of upper and lower external nozzle flap geometry on the external afterbody/nozzle pressure coefficient distributions and external nozzle drag of nonaxisymmetric convergent-divergent exhaust nozzles having parallel external sidewalls installed on a generic twin-engine high performance aircraft model. Nozzle static pressure coefficient distributions along the upper and lower surfaces near the model...

The electronic recording of pulsed-laser holograms is proposed. The polarization sensitivity of each resolution element of the detector is controlled independently to add an arbitrary phase to the image waves. This method which can be used to simulate heterodyne recording and to process three-dimensional optical images, is based on a similar method for heterodyne recording and processing of continuous-wave holograms.

The reactor at AFRRI is a Mark F, 1 megawatt TRIGA (training, research, isotope, General Atomic) reactor. The reactor hangs in a cloverleaf- shaped tank that contains 15,000 gallons of demineralized water. The aluminum tank varies in thickness from 1/4 inch for the exposure room projections to 1/2 inch for the tank bottom. Eighty percent of the reactor building and all of the reactor tank are below ground level. Algae growth in the reactor tank stimulated efforts to remove the algae from the...

The quest for higher power yet smaller electronics has given rise to the need for very effective cooling of these electronics. Because one of the foremost problems in electronics cooling is achieving high heat flux cooling within small packages while expending minimal pumping power, one focus of this study was to investigate the effects of channel curvature on the CHF. Experimental data were obtained for flow rates of 1-7 m/s, subcoolings of 5-35 deg C, and radii of curvature of 25.4 and 50.8...

The PM-3A Type 1 Serial 2 core was removed from the reactor because of increasing fission product levels in the primary coolant. This increase in level was believed associated with defects in the 347 stainless steel fuel cladding. This examination was to locate defects and determine their cause. Cracks were found to penetrate the outer clad of the tubular elements in high- performance regions. All cracks were longitudinal and intergranular, generally starting at the outer tube surface and...

High-pressure heat-transfer experiments have been conducted with both 90 and 98% H2O2. Electrically heated 3/16- and 1/4-in.-dia ft/sec. Titration of the peroxide after short-duration testing indicated that little or no H2O2 decomposition had occurred in the test section. The short-duration burnout tests have shown that the maximum burnout heat flux is directly proportional to coolant velocity and is insensitive to coolant pressure. The Dittus-Boelter equation was found to yield a conservative...

The use of on-board high-energy devices such as megawatt lasers and microwave emitters requires aircraft system integration of thermal devices to either get rid of waste heat or utilize it in other areas of the aircraft. Nonchemical lasers are among the most challenging applications due to their low cooling temperature requirements (67 degrees F) and high waste heat generation times of order 20 s. (Microwave devices will be cooled at 157.7 degrees F.) One plan calls for the rapidly generated...

On the convex surface of the blade the film cooling is essentially absent in a triangular region...

A literature search to identify coolant candidates to be considered for replacing the ice-water system in a portable life support unit led to the following considerations: CO2, an NH3-CO2 mixture, and a salt such as potassium acid fluoride incorporated into ice. In the CO2 system, solid CO2 will sublimate and the resultant gases warm to 4 C, then be expelled from the suit. The heat absorption for this process is 153.0 Kcal/kg. To achieve 504 Kcal (2000 Btu) of cooling, 3.3 Kg (7.3 lbs) of CO2...
