The effect of cowling on cylinder temperatures and performance of a Wright J-5 engine
This report presents the results of tests conducted to determine the effect of different amounts and kinds of cowling on the performance and cylinder temperatures of a standard Wright J-5 engine. These tests were conducted in conjunction with drag and propeller tests in which the same cowlings were used. Four different cowlings were investigated varying from the one extreme of no cowling on the engine to the other extreme of the engine completely cowled and the cooling air flowing inside the cowling through an opening in the nose and out through an annular opening at the rear of the engine. Each cowling was tested at air speeds of approximately 60, 80, and 100 miles per hour.

The Fabrication of Stainless Steel-Uranium Dioxide Fuel Elements
Abstract: "Stainless steel-clad fuel sheet 0.020 in. thick with a 0.008-in. core of stainless steel plus UO2 was produced by roll cladding a powder metal compact. The effects of processing variables, core-matrix composition, quantity of oxide, and oxide particle size on the properties of the sheet were investigated. The strength and ductility of the core decreased sharply as the quantity of oxide in the core increased from 20 to 40 w/o. Over the range of matrix compositions investigated the particle size of the oxide had little affect on the core strength. In cores containing 21 w/o of oxide. 18 w/o chromium, 82 w/o iron matrix prepared from the elemental metal powders had the highest strength and ductility, but this matrix was susceptible to cracking during thermal cycling. As elemental 18 w/o chromium, 9 w/o nickel, 73 w/o iron matrix was the most satisfactory from the standpoint of fabrication and over-all characteristics of the resulting sheet."

High Altitude Performance Investigation of J65-B-3 Turbojet Engine With Both JP-4 and Gaseous Hydrogen Fuels
Memorandum presenting an investigation to determine the performance of the J65-B-3 turbojet engine with JP-4 and gaseous-hydrogen fuels. With JP-4 fuel, the maximum altitude for stable combustion was from about 60,000 to 65,000 feet, and the ultimate blowout limit was at an altitude of about 75,000 feet. The steady-state performance with either fuel decreased considerably with increasing altitude.

Determination of Diffusion Cooling in Graphite by Measurement of the Average Neutron Velocity
From Abstract: "The diffusion cooling coefficient in graphite has been determined by measuring the change in the asymptotic average velocity with buckling, by pulsed neutron methods. The times necessary to establish equilibrium spectra in graphite and heavy water have been measured and are reported."

The Supercritical Water Reactor
From summary: "During 1951 NDA has, at the request of ORNL, been studying the supercritical-water reactor as proposed for aircraft propulsion in Wash-24...This study has concerned itself only with the reactor and shield." The report describes the reactor and the processes involved in developing it. The goal of the development of this reactor is identified as a path to supersonic flight.

Initial Investigation of the Mechanical Properties of Uranium at Elevated Temperatures
Introduction: "Knowledge of the mechanical properties of uranium at elevated temperature is essential in order to understand and predict the fabrication characteristics and pile behavior of this metal. This report presents the experimental data obtained from beta heat-treated specimens which were originally machined from one production, alpha-rolled uranium rod."

An Exact Analysis of Limited Plane Plasma in a Magnetic Field
Introduction: "Prior analyses of a plasma in a magnetic field have been limited, as far as the writer is aware, to cases in which the relative change in field over the orbital distance and the relative change in ion concentration are both small, or in which the relations have been viewed in a purely hydrodynamical way. The first approach excludes cases which can be of considerable interests, for it fails near a plasma edge. The second loses all sight of the structure imposed by the orbital motions."

Geological Investigation of Mexican Cry Mesa, Lukachukai District, Arizona with Diamond Drilling Recommendations
Abstract: The Salt Wash member of the Jurassic Morrison formation of Mexican Cry Mesa, Lukachukai District, Arizona, was examined to determine size, grade, and distribution of contained carnotite deposits and the possibilities of developing reserves by exploratory drilling. Only three occurrences of carnotite-bearing sandstone were found in 17 miles of rim outcrop. Limited drilling is recommended in the vicinity of these exposures.

Investigation of Subsurface Isorad Methods, Temple Mountain, San Rafael District, Utah
From abstract: The subsurface isorad method is an attempt to locate areas favorable for uranium ores by the use of contour maps which show localities having greater radioactivity. The construction of isorad maps entails the measurement of the area under the curve of a gamma-ray logo The figures obtained indicate relative amounts of gamma radiation and are used to locate the isorad contours. This work was started at Temple Mountain in the San Rafael Swell area during the spring of 1952. The purpose of this investigation is to determine the most effective and economic hole spacing for subsurface isorad work.

The Effects of Neutron Bombardment on the Electrical Resistance of Aluminum, Beryllium and Tuballoy (Uranium)
Abstract. Wigner effects on aluminum, beryllium, and tuballoy have been studied by the electrical resistance method. Samples were exposed during an interval which would have produced an increase of approximately 22% in resistance of AGOT-K graphite. The resistance of tuballoy increased approximately 1%. It is shown that the increase can be accounted for by the amount of fission product impurity formed during the exposure. Neither aluminum nor beryllium showed any change. In the case of Be, the Wigner effect may be obscured, to some extent, by the approximately .2 - .3 atom % of impurity present in the samples. Based on the increase occurring in ADOT-K graphite, a change of approximately .2 - .5 x10-6 ohm-om might be expected in the case of Be. The accuracy of the method was sufficiently great to detect a change of this magnitude. Other experiments with Be will be undertaken when purer samples are available. Meanwhile, some samples of the present type ae being subjected to further irradiation.

The Dissolution of Thorium Metal and Thorium Dioxide in HNO3 - HF and HNO3- ( NH4 ) 2 SiF6 Mixtures
Abstract. A satisfactory method has been found for dissolving thorium metal and thorium oxide in heat-treated 25-12 stainless steel vessels without excessive corrosion of the vessels. The dissolution medium consists of strong HNO3 containing a small amount of fluoride or fluo-silicate. the fluoride required has no harmful effects on a subsequent solvent-extraction step for a separation of uranium isotopes from the dissolved thorium.
