Accuracy of Relaxation Length Measurements

Description: We consider here the accuracy of relaxation lengths measured during the water-uranium lattice experiments. Since such an analysis for all measurements would take a great deal of time, we have applied it to just one lattice. This one (2:1 water-to-metal ratio) was chosen completely at random.

The Calculation of Pressure on Slender Airplanes in Subsonic and Supersonic Flow

Description: "Under the assumption that a wing, body, or wing-body combination is slender or flying at near sonic velocity, expressions are given which permit the calculation of pressure in the immediate vicinity of the configuration. The disturbance field, in both subsonic and supersonic flight, is shown to consist of two-dimensional disturbance fields extending laterally and a longitudinal field that depends on the streamwise growth of cross-sectional area. A discussion is also given of couplings, between… more

A correlation by means of transonic similarity rules of the experimentally determined characteristics of 18 cambered wings of rectangular plan form

Description: The effects of one type of camber on the aerodynamic characteristics of rectangular wings at high subsonic and transonic speeds have been studied by applying the transonic similarity rules to the correlation of experimental data for a series of 18 cambered wings having NACA 63A2XX and 63A4XX sections, aspect ratios from 1 to 4, and thicknesses from 4 to 8 percent. The data were obtained by use of a transonic bump over a Mach number range of 0.6 to 1.1.

Creep Strength of Uranium Alloys at 1500 and 1800 F

Description: Abstract:"The creep resistance of various uranium binary alloys was investigated at 1500 and 1800 F in vacuum. Tests were made on alloys of uranium with beryllium, columbium, molybdenum, tantalum, titanium, and zirconium and on molybdenum-UO2 composites. Of the alloys examined, those of the uranium-molybdenum system exhibited the best creep resistance. At 1500 F, creep rates of about 0.005%/hr were produced in uranium-molybdenum alloys by a stress of 2500 psi and, at 1800 F, similar creep rates… more

Effects of wing elasticity on the aerodynamic characteristics of an airplane configuration having 45 degrees sweptback wings as obtained from free-flight rocket-model tests at transonic speeds

Description: Flight testing at transonic speeds occurred on two rocket-propelled models of an airplane configuration with 45 degree sweptback wings of aspect ratio 4 and with different stiffnesses. Longitudinal stability, lift, and drag characteristics were determined by analysis of the response of the models to disturbances in pitch. Results regarding lift, model vibrations, aeroelastic effects on lift, static stability, damping in pitch, and drag are provided.

Free-Fall Measurements of the Effects of Wing-Body Interference on the Transonic Drag Characteristics of Swept-Wing-Slender-Body Configurations

Description: Report presenting the results of testing of bodies and wing-body combinations by the free-fall method in order to provide information about drag characteristics of airplanes and their component parts at transonic speeds. Two models with a fineness-ratio-12 body of revolution with 45 degree sweptback wings located at different positions were dropped and equipped with improved drag measuring instrumentation and pressure measuring orifices on the portion of the body expected to be influenced by th… more

A Hanford Works Vacuum System

Description: The remodeling, fabrication, and instrumentation of a high vacuum system are described. The faults encountered with the old system and their solution are outlined. Tests were made on diffusion pump oils and on the reduction of pump oil back diffusion. The measurement of high vacuum pressures by a cold cathode ionization gage at various points on a vacuum system are discussed.

Investigation of the Effects of Wing and Tail Modifications on the Low-Speed Stability Characteristics of a Model Having a Thin 40 Degree Swept Wing of Aspect Ratio 3.5

Description: Report presenting an investigation of the effects of wing and tail modifications on the low-speed stability characteristics of a model with thin 40 degree swept wings of aspect ratio 3.5. The main purpose was to improve some of the undesirable longitudinal stability characteristics observed in flight of several airplanes with similar wing geometry. The use of flaps, the position of the horizontal tail, and the use of chord extensions are all explored as possible solutions.

Matched performance characteristics of a 16-stage axial-flow compressor and a 3-stage turbine

Description: Report presenting component performance data for one modification of a 16-stage compressor and a 3-stage turbine to determine the matched performance characteristics of an engine with those components. The compressor surge line and infinite exhaust-nozzle-area equilibrium operating line restricted the region of matched compressor-turbine operation. Results regarding the engine operation with modified compressor and three-stage turbine, effect of leakage on engine operation, component efficienci… more

Permissible limits for reactor cooling water assimilated by humans

Description: A permissible limit for the release of waste cooling water from the Hanford reactors into the Columbia River must be determined not only from the effect on humans of assimilation of the radioactive isotopes in the water, but also from the effects of temperature, submersion dose, and metabolism of radioisotopes on fish and other aquatic life in the river, and of concentration in plants of the radioisotopes in irrigation water from the river, with eventual consequences to humans.

Process Test MR-105-15, Production increases by the use of venturi orifices

Description: Process Test MR-105-14 presented the basis for the use of supplemental and venturi orifices in certain regions of a reactor operating in accordance with the scram before boiling limit, and provided for the reactor testing of the supplemental orifice. It is the purpose of the test, described in this report to demonstrate the feasibility of using venturi orifices on a reactor so that maximum production gains may be achieved under this new limit.
