Uranium Concentration Meter

Description: From abstract; "Two basic instruments were developed for determining the concentration of uranium in solutions. Both instruments detect the gamma activity present in a sample solution, and interpret this analysis into direct presentation as parts per million."

Plasma Confinement at Uniform Temperature

Description: Report discussing the properties of a plasma held in a steady state by a magnetic field. Properties such as "electric and magnetic fields, current density, particle density, and macroscopic velocity" are determined analytically by assuming uniform temperature throughout the plasma.

Production of Large Energetic Neutral Deuteron Beams

Description: Introduction: A proposal for using an energetic neutral deuteron beam for injection into a mirror machine has been made by Eugene Lauer. This report describes an experimental attempt to produce a large neutral deuteron beam. The beam from the NTA ion source was passed through a target of hydrogen gas where the charge exchange mechanics produced a beam of energetic neutral deuterium atoms.

Hot Semiworks summary: Run PX-13

Description: This report provides a summary of the Hot Semiworks Unit Run PX-13. During Run PX-12 acceptable HA Column decontamination was demonstrated; however, generally under unstable column operating conditions. The principal objectives of PX-13 were: To duplicate the high PX-12 decontamination factors under stable HA Column operating conditions; to study the effects of fresh solvent, IO Column CP carbonate washed solvent, and IO Column Technical grade carbonate washed solvent on A Column decontaminatio… more

Some Effects of Sweep and Aspect Ratio on the Transonic Flutter Characteristics of a Series of Thin Cantilever Wings Having a Taper Ratio of 0.6

Description: Report presenting an investigation of the flutter characteristics of a series of thin cantilever wings with taper ratios of 0.6 for a range of Mach numbers. Results regarding flutter frequencies, time histories, effects of sweep on the flutter-speed ratio, effects of aspect ratio on the flutter-speed ratio, effects of additional models on the reference flutter speed, application of the flutter-speed ratio, and modified experimental flutter-speed coefficient are provided.

Investigation of local heat-transfer and pressure drag characteristics of a yawed circular cylinder at supersonic speeds

Description: Local heat-transfer coefficients, temperature recovery factors, and pressure distributions were measured on the front side of a circular cylinder at a nominal Mach number of 3.9 over a range of free-stream Reynolds numbers from 2.1 x 10 to the 3rd power to 6.7 x 10 to the 3rd power and yaw angles from zero degrees to 44 degrees. Yawing the cylinder reduced the heat-transfer coefficients and the pressure drag coefficients. The amount of reduction may be predicted by a theory presented herein.

Intensity, scale, and spectra of turbulence in mixing region of free subsonic jet

Description: Report presents the results of the measurements of intensity of turbulence, the longitudinal and lateral correlation coefficients, and the spectra of turbulence in a 3.5-inch-diameter free jet measured with hot-wire anemometers at exit Mach numbers from 0.2 to 0.7 and Reynolds numbers from 192,000 to 725,000.

Low-Speed Static Stability Characteristics of a Complete Model with an M-Wing in Mid and High Positions and with Three Horizontal-Tail Heights

Description: Report presenting an investigation of the low-speed static longitudinal and lateral stability characteristics of a model with an M-wing in mid and high positions and with three horizontal-tail heights. The wing had its sweep discontinuity at 40-percent wing semispan, an aspect ratio of 6, a taper ratio of 0.60, NACA 65A009 airfoil sections parallel to the plane of symmetry, and 45 degrees sweep of the quarter-chord lines. Results regarding longitudinal stability characteristics and lateral stab… more

Use of Truncated Flapped Airfoils for Impingement and Icing Tests of Full-Scale Leading-Edge Sections

Description: From Summary: "In an effort to increase the operational range of existing small icing tunnels, the use of truncated airfoil sections has been suggested. With truncated airfoils, large-scale or even full-scale wing-icing-protection systems could be evaluated. Therefore, experimental studies were conducted in the NACA Lewis laboratory icing tunnel with an NACA 651-212 airfoil section to determine the effect of truncating the airfoil chord on velocity distribution and impingement characteristics. … more

Aerodynamic Loads on an External Store Adjacent to a 60 Degree Delta Wing at Mach Numbers From 0.75 to 1.96

Description: Report presenting an investigation to determine separately the aerodynamic characteristics of a Douglas Aircraft Company store and a semispan delta-wing-fuselage configuration in the presence of one another. The store was located at the 50-percent-semispan station with the store nose both ahead of and behind the wing leading edge for two longitudinal and three vertical positions.

Theory of self-excited mechanical oscillations of helicopter rotors with hinged blades

Description: Vibrations of rotary-wing aircraft may derive their energy from the rotation of the rotor rather than from the air forces. A theoretical analysis of these vibrations is described and methods for its application are explained in Chapter one. Chapter two reports the results of an investigation of the mechanical stability of a rotor having two vertically hinged blades mounted upon symmetrical supports, that is, of equal stiffness and mass in all horizontal directions. Chapter three presents the th… more

EXAMINATION OF TITANIUM PULSE FEEDER DIAPHRAGM FAILURE

Description: A Ti pulse feeder diaphragm failed by cracking after 450 hr service in the Homogeneous Reactor Test mock-up. The diaphragm, which was made of MST Grade III Ti, was vibrated at 78 cpm at 40 to 50 deg C. One side of the diaphragnn was exposed to demineralized H/sub 2/O and the other side was exposed to 10g U/l UO/ sub 2/SO/sub 4/ solution. The main corrosion product was TiO/sub 2/. (W.L.H.)
