The following report describes the high pressure and temperature homogeneous reactor experiment which has been started at Los Alamos, as well as the hazards and safety aspects for the experiments.

Report discussing an experiment testing the severity of attack of an aluminum slug jacket containing one or more spots hotter than the rest of the jacket. These conditions match those likely to exist in a poorly bonded slug.

The increase in process tube outlet water temperature to 90{degree}C resulted in increased emergency water flow requirements as indicated by recently approved curves which establish minimum crossheader pressure requirements for the first three minutes following an electrical power failure. To determine whether 190 Building secondary process water pump capacities are adequate for current minimum reactor water pressure requirements, process water pump trip-cut tests are being conducted at all reactors by the Process Unit in accordance with recommendations of the Reactor Process Committee. The results obtained to data in these tests, as well as current plans for the remaining tests, are presented in this document.

Abstract: Cadmium ratios for very thin (neutron and beta-wise) foils of thorium, gold, vanadium and indium have been measured in the glory hole of the WBNS. These cadmium ratios, together with the known thermal cross sections and a given calculated resonance integral for gold, were used to evaluare the resonance integrals of thorium, vanadium, and indium.

Memorandum presenting some recently obtained data on the aerodynamic characteristics of low-aspect-ratio wings at supersonic Mach number of 4.04 and 6.9 and discusses some new methods of predicting the lift and drag of such wings. The plan forms, airfoil sections, and thickness ratios of the wings tested are provided.

From Introduction: "Afterburning is well established as an effective means of increasing the thrust of a turbojet engine. In order to obtain the maximum thrust from an afterburner, it is necessary to burn to the highest temperatures possible (reference 1). At these high temperatures, material limitations (reference 2) necessitate the installation of cooling systems to permit safe and reliable operation."

Memorandum presenting a preliminary development program on can-type pilot burners as part of an overall program to develop a high-altitude, low-drag ramjet combustor. Results regarding single-row circular pilot burners, six-row circular pilot burners, and annular-segment pilot burners are provided.

Report presenting the laminar flame velocities of propane and ethylene with various oxygen-nitrogen mixtures as determined from schileren photographs of Bunsen-type flames. Flame velocity was determined as a function of equivalence ratio for each oxygen-nitrogen mixture at two initial temperatures.

From Introduction: "The purpose of this paper is to provide further information on the effects of Reynolds number on the aerodynamic characteristics of the wing of reference 1 as well as to provide load distributions for the wing at Mach numbers of 1.6 and 1.9."

Report presenting testing of a 20 degree semiangle conical-inlet ramjet engine with a design Mach number of 2.13 in free supersonic jets to determine the inlet and combustion performance over a fuel-air ratio and Mach number range. Results regarding preflight and flight testing are provided.

Report presenting an investigation in the Langley 300 mph tunnel to determine the low-speed static stability and control characteristics of a model of the Bell X-1 airplane equipped with a 4-percent-thick, aspect-ratio-4 wing. Tests were also made to determine optimum flap deflection for a slotted flap. Results regarding longitudinal stability and control, high lift devices, lateral and directional stability, and lateral and directional control are provided.

Report presenting some laminar-flame-velocity data surveyed with respect to the correspondence between experimental flame velocities and values predicted by semitheoretical and empirical methods.

"An investigation was conducted to determine the effectiveness of suction applied through a porous area at the leading edge of the flap, on a 35 degree sweptback wing. Several chordwise extents and positions of area suction were tested for the suction flap deflected 55 degrees and 70 degrees. The results indicated that large increases in flap lift increment can be made by applying suction with very small flow quantities to an area near the leading edge of a flap" (p. 1).

Report presenting the results of a wind-tunnel investigation of the torsional damping characteristics of a constant-chord control surface. The results indicated that the damping coefficient at supersonic speeds was near zero with a tendency toward instability at low supersonic Mach numbers. Results regarding theory, damping moments, and restoring moments are provided.

The laminar-flame-velocity data previously reported by the Lewis Laboratory are surveyed with respect to the correspondence between experimental flame velocities and values predicted by semitheoretical and empirical methods. The combustible mixture variables covered are hydrocarbon structure (56 hydrocarbons), equivalence ratio of fuel-air mixture, mole fraction of oxygen in the primary oxygen-nitrogen mixture (0.17 to 0.50), and initial mixture temperature (200 degrees to 615 degrees k). The semitheoretical method of prediction considered are based on three approximate theoretical equations for flame velocity: the Semenov equation, the Tanford-Pease equation, and the Manson equation.

The hiring schedule was reviewed by the same method that was used in the reference letter with essentially the same results; that is, that we should hire approximately 125 technical graduates during the hiring year 1953-54. In the belief that possibly this method was a bit too crude for this stage of the Plant development, I have applied another one, which I believe is fairly independent of the previous method of calculation since it is directed at a consideration of only people required who have a technical background.

This report studies the reactions between gaseous uranium hexafluoride and several gaseous reagents for possible analytical application that has been underway while using a buggy designed for gaseous titration studies. This study primarily focuses on methods to analyze gases containing uranium hexafluoride and physically absorbed uranium hexafluoride.
