Hydrodynamic investigation of a model of a supersonic multijet water-based aircraft with engines exhausting from the step

Description: Report presenting an investigation of the hydrodynamic characteristics of a multijet water-based aircraft capable of supersonic speeds and with jet engines exhausting through the step. The step engine exhausts were found to considerably increase afterbody wetting and smooth-water resistance, but they had no significant effect on longitudinal stability. Results regarding spray characteristics, resistance and stability at constant speed, take-off stability, landing stability, and jet noise are provided.

Experimental Investigation of Creep Bending and Buckling of Thin Circular Cylindrical Shells

Description: "Forty-three cylinders of 40-inch length and 16-inch diameter, made of 5052-0 aluminum-alloy sheets of 0.023-, 0.040-, 0.051-, and 0.064-inch thickness, were subjected to bending moments constant along the cylinder and in time in an oven which maintained a constant temperature of 500 degrees Fahrenheit during the test. All the cylinders failed by buckling. The time that elapsed between load application and collapse was measured" (p. 1).

Analysis of Wing Loads on a Flexible Swept-Wing Jet Bomber During Push-Pull Maneuvers

Description: Report presenting measurements of the loads of the wing of a Boeing B-47A medium bomber using strain-gage instrumentation during 23 symmetrical push-pull maneuvers at a variety of altitudes, Mach numbers, and gross weights. Time histories of aerodynamic shear, bending moment, and torque at each of four spanwise stations on the left wing and one on the right wing were created. Based on the results, presently available methods seem to be capable of predicting additional and basic loads accurately within the range of flight conditions in the test.

EFFECT OF APPR-1 CONTROL ROD ACCELERATION AFTER SCRAM ON STARTUP ACCIDENT

Description: In the preoperational checkout of the APPR-1 it became apparent that the control rod acceleration after scram was lower than expected. It was expected that the control rod acceleration after scram would be 0.750 g(1) where g is the acceleration of gravity. However, measurements made at Ft. Belvoir indicated an acceleration of 0.4 g. The effect of this reduced acceleration on the safety of the APPR1 is reported in this memo. In the operation of the APPR1 the most dangerous condition exists at cold startup. Therefore the behavior of the APPR-1 in a startup accident with a rod acceleration of 0.4 g after scram is considered. Analysis of the most adverse startup accident in the APPR-1 indicated that at the 15 Mw level scram the reactor is on a 33 ms. period. Rod insertion begins after a 50 ms. instrument delay, at which time the power is 80 Mw. The maximum power reached with a rod acceleration of 0.4 g is 96.5 Mw. The total energy released is about 5.8 a 10/sup 3/ Btu which is far below the 8 x 10/sup 4/ Btu which would result in melting at the center line of the fuel element (and probable core destruction). If the rod acceleration were 0.759 g the maximum power would be between 80 and 90 Mw so that the reduced acceleration does not constitute any significant increase in energy release on a starting accident.

Drilling in the Flatirons Locality, Monument Valley, Arizona

Description: From introduction: A subsurface exploration program was undertaken to investigate the concentration of uranium and vanadium in or near the base of the Shinarump member of the Chinle formation in the Flatirons locality, and to develop criteria whereby adjacent unexplored areas could be evaluated as to potential production capacity from study of geological and mineralogical features at the host rook outcrop. An earlier study of the area by C. G. Evensen of the U. S. Atomic Energy Commission had shown that geological conditions favorable to the accumulation of commercial uranium deposits were present in the Flatirons area.

Monitoring of direct chemical assay of fabricated parts

Description: The specification for the plutonium content of fabricated parts requires that for each three-months production a statistical estimate be made of process variance (variation in actual plutonium content from part to part). Prior to the fourth quarter of 1956, this requirement was met by the following indirect technique: Chemical assay was made of at least one-half the parts produced; by-difference analysis (subtraction of the measured impurities from 100 per cent) was made of all parts produced; and the chemical assay and by-difference measurements were analyzed to permit partition of the observed, between-part variance in chemical assay results into process variance and analytical variance.

Effect of fuel variables on carbon formation in turbojet-engine combustors

Description: Report presents the results of an investigation of the effects of fuel properties and of a number of fuel additives on combustion-chamber carbon deposition and exhaust-gas smoke formation in a single tubular turbojet-engine combustor. Limited tests were conducted with a number of the fuels in several full-scale turbojet engines to verify single-combustor data.

A Hydraulic Power Unit for Solvent Extraction Column Pulse Generators

Description: A power unit comprised of a reciprocating hydraulic cylinder controlled by hydraulic, mechanical, and electrical elements was developed to drive pulse generators for solvent extraction columns in the Purex Hot Semiworks. Design bases included remote control of continuouslyvariable pulse amplitudes between 1/ 2 and 1/2 inches, and pulse frequency up to 120 cycles/min. Each of nine power units operated 30 to 60 million cycles without serious difficulty, although minor modifications and corrections were made during scheduled shutdowns of the Semiworks. Operational irregularities, such as erratic or drifting amplitudes, occurred with sufficient frequency to indicate deficiencies in the original design. The triangular pulse wave which is characteristic of the power unit was suspected on several occasions as having an adverse effect on extraction column performance. However, no correlation was found to show that column performance is adversely affected by the triangular pulse. (auth)

Uranium oxide activation cost study

Description: Owing to continuous uranyl nitrate calcining facilities at Hanford, the reactivity of the A oxide produced was reduced, with lower conversion to UF{sub 4}. A process design was developed for increasing the A{sub 3}O{sub 8} activity by fluidized-bed reduction to UO{sub 2} and reoxidation to A{sub 3}O{sub 8}. Justification for the installation would be in the $250,000 to $300,000 saved in not needing additional fluorine cells and $310,000 per year operating cost savings. The installation would cost $700,000 or $860,000; operating cost would be $270,000 per year. It was concluded that a full-scale process cannot be justified at the time of the study.
