Calculated Performance of a Direct-Air Nuclear Turbojet-Powered Airplane Using a Split-Flow Reactor and a Separated-Type Shield

Description: Memorandum presenting an analysis made to estimate the performance of a direct-air nuclear turbojet-powered airplane with a split-flow reactor and a separated-type shield. The analysis was for flight Mach numbers of 0.9 and 1.5 and covered a range of altitudes, reactor-wall temperatures, turbine-inlet temperatures, compressor pressure ratios, and airplane lift-drag ratios.

The Chelate Process, VI. Process flow involving o-dichlorobenzeneas the solvent for TTA

Description: Comparative studies of a series of halogenated solvents, as carriers for TTA in the chelate process for plutonium extraction, indicate that ortho-dichlorobenzene most nearly satisfies the requirements that are set forth. A complete process design is presented for use with this solvent, and flow data and equipment capacities are given for dissolver solution and for uranium-free fission product solution as alternate feeds to the process. Vertical mixer-settlers are recommended as the contractors,… more

Complex Ions of Lanthanum in Aqueous Solutions

Description: The complexing of lanthanum by various anions and weak acids was investigated by observing the light absorption of the complex formed with thenoyltrifluoracetone (TTA). This species showed the properties needed for a satisfactory specgtrophotometric method of analysis.

Compressor Performance Characteristics of a Python Turbine-Propeller Engine Investigated in Altitude Wind Tunnel

Description: Report presenting an investigation in the altitude wind tunnel to determine the performance of the Python turbine-propeller engine. Compressor-performance data were obtained for a range of simulated altitudes at a single cowl-inlet ram pressure ratio while the engine was run over its full operable range of engine speeds. Results regarding the deterioration of compressor performance, compressor performance, including efficiency and performance maps, and velocity and static-pressure profiles are … more

The Constitution Diagram of Uranium-Rich Uranium-Molybdenum Alloys

Description: The colybdenum-uranium equilibrium diagram has been studied, and the results are presented up to 50 atomic per cent molybdenum. Additions of molybdenum raise the melting point of uranium, forming a peritectic at about 1285 C. The solubility of molybdenum in gamma uranium is extensive. It decreases from 42 atomic per cent at the peritect temperature to 30 per cent at lower temperatures. Allots of about 28 to 30 per cent molybdenum content have been found to contain a metastable gamma. It can be … more

A Continuous Fission Product Separation Process; I. Removal of the Rare Earths (Lanthanum Cerium, Praseodymium, and Neodymium) From a Typical Liquid Bismuth-Uranium Reactor Fuel by Contact with Fused LiCl-KCl Mixtures

Description: Technical report investigating the distribution of rare earth elements between a liquid bismuth-uranium solution and fused KCI-LiCi mixtures. Report warrants further research on the liquid bismuth-uranium-fused salt system due to the benefit of continuous fission removal processes.

Determination of half life of polonium-210 by counting: final report

Description: Introduction: "A number of determination have been made of the half life of polonium-210 by calorimetry. Counting affords an entirely different method of determining half lives and requires only a small amount of activity. Therefore for comparison a half-life determination by counting was undertaken with a sample of approximately 0.5 millicurie of polonium."

Development of Zirconium Alloys. Part 1

Description: A number of alloys of zirconium have been investigated as part of a program aimed at improving the high-temperature tensile strength of zirconium. These alloys include molybdenum, tantalum, tungsten, tin, titanium, and nitrogen alloys. It was found that small additions of molybdenum, tantalum, tin, titanium, and nitrogen appreciably increase the high-temperature tensile strength of zirconium.

Direct Measurements of Skin Friction

Description: "A device has been developed to measure local skin friction on a flat plate by measuring the force exerted upon a very small movable part of the surface of the flat plate. These forces, which range from about 1 milligram to about 100 milligrams, are measured by means of a reactance device. The apparatus was first applied to measurements in the low-speed range, both for laminar and turbulent boundary layers. The device was then applied to high-speed subsonic flow and the turbulent-skin-friction … more

The Effects of Atomic Weapons on Glazing and Window Construction. Annex 3.5 of Scientific Director's Report of Atomic Weapon Tests at Eniwetok. 1951. Operation Greenhouse

Description: BS>Various types of wood, steel, and aluminum window construction, glazed with plastic and different kinds of glass, were installed on four sides of a test structure during the greenhouse tests in order to determine their relative resistance to an atomic blast. The degree of protection from flying glass provided by mounting Venetian blinds, insect screens, and 1/4-in. mesh wire netting on the inside of window openings was also determined. The best results seem to indicate that the resistances o… more

Error in Airspeed Measurement Due to Static-Pressure Field Ahead of the Wing Tip of a Swept-Wing Airplane Model at Transonic Speeds

Description: From Summary: "As part of a study of means of airspeed measurement at transonic speeds the use of static orifices located ahead of the wing tip has been investigated for possible application to service or research airspeed installations. The local static pressure and local Mach number have been measured at a distance of 1 tip chord ahead of the wing tip of a model of a swept-wing fighter airplane at true Mach numbers between 0.7 and 1.08 by the NACA wing-flow method. All measurements were made … more

Exploratory Studies of Hydrazine Formation by Radioactive Ionization

Description: The production yields of hydrazine by various ionization methods are compared. The maximum value of M/N (number of molecules reacting per ion pairs) for electric discharge was 0.25 and for beta particles on liquid ammonia, M/N = 0.31. A 1-Mev reactor could produce 1.6 kg of hydrazine per hour if M/N = 0.04 as determined by alpha particles on liquid ammonia. About 300 ev of energy were needed to form a hydrazine molecule. (C.J.G.)
