Preliminary Low-Speed Wind-Tunnel Investigation of Some Aspects of the Aerodynamic Problems Associated with Missiles Carried Externally in Positions Near Airplane Wings
A low-speed wind-tunnel investigation has been made of some aspects of the aerodynamic problems associated with the use of air-to-air missiles when carried externally on aircraft. Measurements of the forces and moments on a missile model for a range of positions under the mid-semispan location of a 45deg sweptback wing indicated longitudinal and lateral forces with regard to both carriage and release of the missiles. Surveys of the characteristics of the flow field in the region likely to be traversed by the missiles showed abrupt gradients in both flow angularity and in local dynamic pressure. Through the use of aerodynamic data on the isolated missile and the measured flow-field characteristics, the longitudinal forces and moments acting on the missile while in the presence of the wing-fuselage combination could be estimated with fair accuracy. Although the lateral forces and moments predicted were qualitatively correct, there existed some large discrepancies in absolute magnitude.

Graphite burn-out resulting from carbon monoxide formation in C Pile
With the introduction of carbon dioxide into the piles as a gas atmosphere, new problems arose which concerned the chemical reactions undergone by the pile graphite with the gas atmosphere. In the interest of obtaining a better understanding of the nature and extent of these graphite-gas reactions, mass spectrometer analyses of the pile gas from a selected sampling port at C Pile were initiated at the time of start-up of that unit and were continued until several steady state conditions had been observed. The results of these analyses are presented and discussed herein.

Study of Some Dielectric Properties of Suspensions of Magnesium Particles in Mineral Oil
The variation of dielectric constant has been measured as a function of the concentration of magnesium particles; the shape, size, and degree of oxidation of the particles; the temperature; and the frequency of oscillation. The variation of dielectric constant and settling rate was investigated as a function of time. Also investigated were the effects of particle concentration, shape and time on dielectric losses.

Studies of the lateral-directional flying qualities of a tandem helicopter in forward flight
An investigation of the lateral-directional flying qualities of a tandem-rotor helicopter in forward flight was undertaken to determine desirable goals for helicopter lateral-directional flying qualities and possible methods of achieving these goals in the tandem-rotor helicopter. Comparison between directional stability as measured in flight and rotor-off model tests in a wind tunnel shows qualitative agreement and, hence, indicates such wind-tunnel test, despite the absence of the rotors, to be one effective method of studying means of improving the directional stability of the tandem helicopter. Flight-test measurements of turns and oscillations, in conjunction with analytical studies, suggest possible practical methods of achieving the goals of satisfactory turn and oscillatory characteristics in the tandem helicopter.

Redox contamination: Terminal status report
The Redox ruthenium contamination problem has two distinct phases; the environs contamination as a result of stack emissions, and the in-canyon contamination which controls time and cost factors for plant maintenance. On stack emissions, the probability of serious environs contamination exists so long as the batch-type, permanganate headend ruthenium volatilization process is used. Knowledge of the characteristics of volatilized ruthenium is not adequate today to give complete assurance that the off-gas treatment facilities will satisfactorily remove the particulate and gaseous forms of ruthenium on every headend batch. Until the required knowledge of ruthenium reaction rates is developed, the filtering and scrubbing efficiencies are determined, and the requirements to guarantee 100 percent reliability of equipment operation are solved, the prediction of frequency and amounts of ruthenium emission must be based on the experience factor gained in actual plant operation.
