Aerodynamic Research on Fuselages with Rectangular Cross Section
The influence of the deflected flow caused by the fuselage (especially by unsymmetrical attitudes) on the lift and the rolling moment due to sideslip has been discussed for infinitely long fuselages with circular and elliptical cross section. The aim of this work is to add rectangular cross sections and, primarily, to give a principle by which one can get practically usable contours through simple conformal mapping. In a few examples, the velocity field in the wing region and the induced flow produced are calculated and are compared with corresponding results from elliptical and strictly rectangular cross sections.

Analog Computer Study of the Operation of the Gas-Cooled Loop on the Oak Ridge Research Reactor
An annlog computer study of the ORR gas-cooled loop was made. The effects on fuel and gas temperatures of changing gas (nitrogen) flow rates, turning the heater on and off, and inserting or removing the fuel were determined. It was found that the temperature of the sample, if fuel, could be raised more rapidly than it could be reduced, and that the temperature could be reduced faster with high rates of flow. All of the equations used in building up the computer are given, and some of them are derived. (auth)

Analyses of Experimental Power-Reactivity Feedback Transfer Functions for a Natural Circulation Boiling Water Reactor
ABS>Experimental power-reactivity feedback transfer functions were calculated from the EBWR power transfer function measurements. A simplified model of the EBWR kinetics was developed, using an analog computer, and an analytic expression was obtained for the feedback function. The analytic solution was fitted to the experimental functions to obtain power coefficients and time constants for various modes of operation. These data were extrapolated, and a power transfer function was predicted for 40 Mw. The reactor fumction was measured and compared with the prediction. A stability study was carried out, using open loop transfer functions containing the experimental feedback functions. Extrapolation of the gain and phase margins indicated stability to at least 66 Mw. The reactor was successfully operated at 61.7 Mw following this, with power limited by the capacity of the feedwater pumps. The use of the simplified model for parameter studies is demonstrared by a series of calculations to evaluate the effect of heat transfer time constant on stability. (auth)

Angular Distribution of Photopions From Hydrogen
ABS>An accurate measurement of the differential cross section for the photoproduction of positive pions was made at the Berkeley synchrotron, for photon energies of 280 and 290 Mev. The mesons were produced in a thin-walled liquid hydrogen target, and the meson detection apparatus utilized the characteristic pi -- mu decay of the meson. The measurements were done in two steps, from 0 to 50 deg with equipment specifically designed to reduce a very high positron background, and from 30 to 160 deg with equipment whose efficiency and solid angle could be accurately determined. The experimental results in the small-angle region definitely show the effects of ''photoelectric'' production of pions from the cloud surrounding the nucleon, which are characterized by an abrupt flattening of the cross section in the region forward of 40 deg (c. m.). The results are compared to the theory of photoproduction derived from the dispersion relations, and the sgreement is satisfactory within the limitations of the theory. (auth)

ARGON AS A PROTECTIVE ATMOSPHERE FOR MOLTEN SALTS
In reactors employing circulating molten salt fuels and having most of the Kr and Xe gases stripped from the fuel into the off-gas, argon may reasonably be used as the blanket (and stripping) gas. In such cases, the activity of Kr and Xe and their descendents so far exceeds that of Ar/sup 41/ and K/sup 41/ produced that no additional provision is needed for shielding. The amounts of Rb, Sr, Cs, and Ba are so much greater than that of K that no additional provision against chemical attack is needed. (auth)

A Body Modification to Reduce Drag Due to Wedge Angle of Wing with Unswept Trailing Edge
From Summary: "Ward's slender-body-theory formula for zero-lift drag contains three integrals plus a base-drag term. Two of these integral terms depend only upon the cross-sectional area distribution of the body. The third integral term depends only upon the body shape and axial slopes at the base of the body. This term is neglected in the transonic area rule because in many cases it is zero; however, there are also many cases in which it is not zero. This paper examines the term for the possibility of drag reduction for a particular case."

Casting Uranium-5 W/O Zirconium-1.5 w/o Niobium Alloys Into Zirconium and Zircaloy-2 Containers
A series of experimental castings have been made with the object of exploring the proposition that uranium and high uranium alloys could be bonded to zirconium and zirconium alloys by a direct casting method. Unalloyed uranium and uranium alloyed with 5 wt. % Zr and 1.5 wt. % Nb have been cast into zirconium and Zircaloy-2 molds of vsrious shpes and sizes. Castings made in cans of circular cross section were well bonded and sound, provided the molds were outgassed at elevated temperature before use and proper preheating precautions were observed. Molds of rectangular cross sections, however, did not yield as satisfactory results, mainly because of porosity. The asymmetry of this type of mold probably contributed to the lack of success. Good bonds were obtained between uranium and zirconium by casting into graphite molds lined on opposite sides with zirconium plates. (auth)
