From Summary: "The effect of small downstream pressure distributions on the position of a normal shock in a duct with area variation is analyzed. For the analysis, the gas flow is treated as quasi-one-dimensional, and boundary layer is neglected. The analysis shows that there is a first-order lag relation between shock position and small downstream disturbances in pressure which occur at frequencies below a given limit."

Report presenting a method by which the residual stress distribution in a disk can be determined with the aid of the obliquely mounted strain gage when the directions of the principal stresses are radial and tangential. The strain gages are mounted in such a way as to make them sensitive only to the tangential stresses in the disk. Results regarding cutting procedure, accuracy of the method, and an independent check of the method are required.

Introduction: Atomic Energy Facts is designed to serve as an introduction to nuclear operations in the United States and as a handbook of related information for the use of industrial firms and other active or interested in atomic energy.

Report presenting flat 2024-T3 aluminum panels measuring 11 inches by 13 inches were tested in the near noise fields of a 4-inch air jet and turbojet engine. The stresses which were developed in the panels are compared with those calculated by generalized harmonic analysis. Results regarding noise inputs, panel characteristics, procedure for calculating stress, and comparison of calculated and measured stresses are provided.

The results of the corrosion study are illustrated in a plot of the weight loss of the aluminum--nickel samples with respect to the time at test temperatures of 470 to 485 deg F. The corrosion rate determined by this test indicates that the weight loss per unit time is the same for both the in-pile irradiated specimens and the out-of-pile control specimens which did not have any neutron exposure, except that the out-of-pile specimens had a higher initial rate of corrosion which elevated the curve above that of the in-pile specimens.

Monthly newsletter of the High Plains Underground Water Conservation District No. 1, discussing the field of underground water. Topics include profiles of water conservation research, annual pre-plant soil moisture survey data, annual Winter Water Level measurement data, and information about the latest water conservation tips.

The gamma -radiation field from a battery of 10 MTR spent fuel elements was calculated and a special shipping cask designed to contain the 10 elements. An internal watercooled tank in the cask holds the 10 elements in the vertical position. Two external air-cooled, finned-tube heat exchangers control the water temperature. The sides of the cask open to convert the cask to a radiation source without changing the position of the elements. A unique feature of the design is a device for closing the sides of the cask by gravity in the event of accident or power failure. This provides a ''fail-safe'' safety feature. (auth)

Report presenting an investigation of an axial-flow turbojet engine in the altitude wind tunnel, including limitations on transient operation of the engine in relation to two altitudes and exhaust-nozzle-areas. Results regarding hysteresis, frequency of surge and stall, altitude effect, exhaust-nozzle-area effect, and a comparison of steady-state and transient surge lines are provided.

Note presenting an analysis made to determine the effect of configuration parameters and valve area-time operating relations on the speed of response of the liquid flow and the suppressed suction head of the pump in a rocket motor. The configuration consisted of tank, pump, combustion chamber, valves, and lines, including a bypass line with a valve around the pump. Results regarding the effect of valve resistance-time history on pump suppression head and flow response time and effect of configuration parameters are provided.

Report issued by the Bureau of Mines over studies conducted on bleeder application in bituminous coal mines. The methods and results of the studies are presented. This report includes illustrations.

Report presenting a flight investigation of a large swept-wing bomber airplane in rough air at 5,000 feet to determine the effects of wing flexibility on wing bending and shear strains. Aeroelastic effects were found to be large, particularly at the outboard measuring stations. Results regarding the bending strains and shear strains are provided.

The following report covers the study of the area described in this report that is part of the White Canyon mining district, San Juan County, Utah. Upon this investigation, uranium deposits were discovered and analyzed.

Report presenting equations, tables, and figures for use in the analysis of helium flow at supersonic and hypersonic speeds. Tables are provided for useful dimensionless ratios for continuous one-dimensional flow and normal-shock waves as functions of Mach number. The oblique-shock characteristics of wedges and cones in helium at various Mach numbers are also presented.

Average value of the specific change in length per deuteron per cm/sup 2/ for 8.5-Mev deuterons is 3.8 x l0/sup 21/. This expansion was observed to be a linear function of iniegrated flux. Using a value of l.5 v/sub a/, where v/sub a/ is the atomic volume, for the volume increase due to a Frenkel pair in copper, the calculated concentration of defects is 1/6 that predicted by the simple theory of Seitz and Koehler, nnd DELTA a/ DELTA a/sub max/ equals DL/L to ll% during irradiation on the assumption that the energy dependence of deuteron dnmage in copper varies inversely with the deuteron energy. Where comparison is possible, recovery of DELTA L/ DELTA L/sub max/ follows that of DELTA a/ DELTA a/sub max/ to bettcr than l0%. For DELTA L/ DELTA L/sub max/ 64% of the damage anneals in Stage l (< 70 deg K), 6% anneals in Stage II (70 to l80 deg K) 26% anneals in Stage III (l80 to 300 deg K), and 4% remains at 300 deg K.
