Casting Uranium Bars as a Substitute for the Extrusion Process

Description: The usual method of producing uranium slugs for the reaction pile is to cast the metal into billets which are extruded into rod about 1.45 inches in diameter. Slugs are then machined from this to the final size of 1.359 inches in diameter by 8 inches long. Extrusion is done in the gamma range at a temperature of about 1000 C, where the metal is soft enough to be extruded at relatively low pressures. This operation is difficult and expensive and the product is not entirely satisfactory. The billets must be protected from oxidation during heating and extruding and the extruded rod must likewise be protected during cooling. Loss of metal due to oxidation is appreciable and a relatively large amount of scrap is produced. The production of dies suitable for use at the high temperatures involved is troublesome. The extruded rod must be straightened before machining and frequently contains stringers of oxide and voids or other internal defects.

Charts of Pressure, Density, and Temperature Changes at an Abrupt Increase in Cross-Sectional Area of Flow of Compressible Air

Description: "Equations have been derived for the change in the quantities that define the thermodynamic state of air - pressure, density, and temperature - at an abrupt increase in cross-sectional area of flow of compressible air. Results calculated from these equations are given in a table and are plotted as curves showing the variation of the calculated qualities with the area expansion ratio in terms of the initial Mach number as parameter. Only the subsonic region of flow is considered" (p. 1).

Colorimetric Analysis for Cadmium - Diphenylthiocarbazone (Dithizone) Method

Description: Abstract: The well known colorimetric method for determining cadmium by means of dithizone has been reinvestigated and found applicable to solutions containing interfering ions much as are found in the plant. Copper, however, must be removed prior to using this analytical procedure.

Correlation of Engine-Cooling Data

Description: Report discusses a method of correlating engine-cooling data and its application to a representative engine-cooling test. Considerations for the correlation method are given, but the application to specific engine-cooling problems should be simple and direct. Information about experimental procedure and an example with specific values are included.

Correlation of Wright Aeronautical Corporation Cooling Data on the R-3350-14 Intermediate Engine and Comparison With Data From the Langley 16-Foot High-Speed Tunnel

Description: Report presenting a comparison of the cooling-test data obtained on the identical Wright R-3350-14 engine equipped with the same cooling pressure-tube installation. The comparison reveals the large difference in cooling pressure drop that may be obtained in different test installations with the identical engine and pressure-tube installation because of an injudicious choice of pressure-tube locations.

Critical combinations of shear and transverse direct stress for an infinitely long flat plate with edges elastically restrained against rotation

Description: Report presenting an exact solution and a closely concurring approximate energy solution for the buckling of an infinitely long flat plate under combined shear and transverse direct stress with edges elastically restrained against rotation. An appreciable fraction of the critical stress in pure shear may be applied to the plate without any reduction in the transverse compressive stress necessary to produce buckling.

The Effect of Compression Ratio on Knock Limits of High-Performance Fuels in a CFR Engine 2: Blends of 2,2,3-Trimethylpentane with 28-R

Description: "The knock-limited performance of blends of 0,50; and 100 percent by volume of 2,2,3-trimethylpentane in 28-R fuel determined with a modified F-4 engine at three sets of conditions varying from severe to mild at each of three compression ratios (6.0, 8.0, and 10.0). A comparison of the knock-limited performance of 2,2,3-trimethylpentane with that of triptane (2,2,3-trimethylbutane) is included. The knock-Limited performance of 2,2,3-trimethylpontane was usually more sensitive to either compression ratio or inlet-air temperature than 28-R fuel, but the ratio of the knock-limited indicated mean effective pressure of a given blend containing 2,2,3-trimethypentane and 28-R to the indicated mean effective pressure of 28-R alone was not greatly affected by compression ratio if the engine operating conditions were mild" (p. 1).
