Preparation of Radioiron of High Specific Activity (open access)

Preparation of Radioiron of High Specific Activity

From abstract: "A comparison has been made of methods for producing Fe59 of higher specific activity than that obtainable by irradiating natural iron in the Clinton pile. Five processes have been considered, (1) irradiation of natural iron in the Hanford piles, (2) irradiation of enriched F58 in the Clinton and Hanford piles, (3) Szilard-Chalmers enrichment using ferrocyanides in the Clinton pile, (4) collection of recoils in a phase separable from the bulk of the iron, and (5) the Co59 (n,p) Fe59 reaction in the Clinton and Hanford piles."

Performance of J-33-A-21 and J-33-A-23 Compressors With and Without Water Injection (open access)

Performance of J-33-A-21 and J-33-A-23 Compressors With and Without Water Injection

"In an investigation of the J-33-A-21 and the J-33-A-23 compressors with and without water injection, it was discovered that the compressors reacted differently to water injection although they were physically similar. An analysis of the effect of water injection on compressor performance and the consequent effect on matching of the compressor and turbine components in the turbojet engine was made. The analysis of component matching is based on a turbine flow function defined as the product of the equivalent weight flow and the reciprocal of the compressor pressure ratio" (p. 1).

Ground Tests of a Radial Air-Cooled Engine to Correct a Poor Circumferential Pressure-Recovery Distribution (open access)

Ground Tests of a Radial Air-Cooled Engine to Correct a Poor Circumferential Pressure-Recovery Distribution

"This report presents the results of the tests of a power-plant installation to improve the circumferential pressure-recovery distribution at the face of the engine. An underslung "C" cowling was tested with two propellers with full cuffs and with a modification to one set of cuffs. Little improvement was obtained because the base sections of the cuffs were stalled. A set of guide vanes boosted the over-all pressures and helped the pressure recoveries for a few of the cylinders" (p. 1).

Vibration Survey of Blades in 19XB Axial-Flow Compressor 3: Preliminary Engine Investigation (open access)

Vibration Survey of Blades in 19XB Axial-Flow Compressor 3: Preliminary Engine Investigation

Strain gages were used to measure blade vibrations possibly causing failure in the 10-stage compressor of the 19XB jet-propulsion engine. The seventh and tenth stages were of great concern as a result of failures experienced by the manufacturer. Strain-gage records were obtained from all stages during acceleration, deceleration, and constant speed runs. Curves are presented herein showing the maximum allowable vibratory stress for a given speed, the change of the damping coefficient with the mounting of a strain gage at the base of the blade, the effect of rotor speed, on blade natural frequency, and the effect of the order of first bending-mode vibration on stress. It was found that for all stages the lower the order of vibration the higher the stress but no destructive vibrations were detected.
