Preferential Pumping and Its Application to the P⁴ Experiment

Description: Report analyzing the "preferential removal of neutral gas from an incompletely ionized plasma in which the ionized particles are allowed to drift along magnetic field lines through a differentially pumped channel" and its relation to the P⁴ experiment. The report also analyzes the regenerative and non-regenerative losses of plasma by radial diffusion, as well as "considerations relating to the ultimate disposal of overflow plasma."

TWO-DIMENSIONAL (r,z) MULTIGROUP CALCULATION FOR AN INTERMEDIATE SPECTRUM CRITICAL ASSEMBLY

Description: The results of two-dimensional (r,z) multigroup calculations of an experimental low-power reactor (PPA19) are described. Comparison is made between calculated results and experimental measurements of reactivity, power distribution, and sodium activation. Generally good agreement is observed between calculation and experiment. This calculation was performed in 1954 and represents the first application of Roe's twodimensional multigroup formulation to the analysis of an operating critical assembl… more

Experimental Static Aerodynamic Forces and Moments at High Subsonic Speeds on a Canard Missile During Simulated Launching From the Midsemispan Location of a 45 Degree Sweptback Wing-Fuselage-Pylon Combination at Zero Sideslip

Description: Report presenting an investigation at high subsonic speeds to determine the static aerodynamic forces and moments on a canard missile model during simulated launching from the midsemispan location of a 45 degree sweptback wing-fuselage-pylon combination. Significant variations in all the aerodynamic components were noted with changes in chordwise location of the missile. Results regarding force and moment characteristics and effects of angle of attack and Mach number are provided.

Aerodynamic Forces and Moments on a Large Ogive-Cylinder Store at Various Locations Below the Fuselage Center Line of a Swept-Wing Bomber Configuration at a Mach Number of 1.61

Description: "A supersonic wind-tunnel investigation on store interference has been conducted in the Langley 4- by 4-foot supersonic pressure tunnel at a Mach number of 1.61. Forces and moments were measured on a large ogive-cylinder store in the presence of a 45 degree swept-wing-fuselage bomber configuration for a number of store locations below the fuselage center line. Results of the investigation show that large variations of store lift, drag, and pitch occur with changes in store or airplane angle of… more

Transonic Flutter Investigation of an All-Movable Horizontal Tail for a Fighter Airplane

Description: Memorandum presenting a transonic flutter investigation of a model of an all-movable horizontal tail for a fighter airplane. The model had an aspect ratio of 3.3, a taper ratio of 0.42, and 35 degrees of sweepback of the quarter-chord line. Results regarding the analytical studies and experimental results and comparison with theory are provided.

Growth of Disturbances in a Flame-Generated Shear Region

Description: Results are presented of an experimental and theoretical investigation of the growth of transverse velocity disturbances in the shear region caused by a flame in a duct. In the theoretical stability analysis, a flow field arising from a flame in a duct was analyzed. The flow was neutrally stable to symmetric disturbances and unstable to antisymmetric ones. In the experimental part of the program disturbances of various frequencies were imposed on a flame stabilized in a duct, and the effects we… more

A SIMULATION STUDY OF A REFLECTOR CONTROL SYSTEM FOR A HETEROGENEOUS BOILING REACTOR

Description: The feasibility of using a reflector control system for a heterogeneous boiling reactor through use of analog simulatlon tecbeiques was examined. The reactor kinetics, reactivity, and steam generation were simulated electronically while the hydraulic portion of the reflector system was represented by a full- scale physical mock-up. The two portions of the system were coupled together, and an attempt was made to achieve a stable, nonoscillating system. Various configurations of hydraulic couplin… more

Description of a Thermonuclear Reactor Based on the Use of a Layer of Relativistic Electrons to Confine and Heat the Plasma

Description: A long layer of rotating relativistic electrons was employed in a proposed scheme of a thermonuclear reactor to provide a closed pattern of magnetic field liens and to heat the plasma to fusion temperature. Parameters of a production machine and experimental model are presented. The general requirements for the plasma confinement at adequate density and temperature are summarized. Establishment of the electron layer is described. The equilibrium of the plasma under these conditions was investig… more

Results of experimental tests simulating slow plugging of a BDF process tube

Description: The purpose of this report is to present the results of an experimental program investigating the transient response of a BDF process tube to sudden plugging of the coolant stream. The program was directed toward determining the degree of protection offered by the Panellit pressure gage system to the hazards arising from flow reductions following such plugs.

Spectrophotometric Determination of Cerium With Tiron

Description: A spectrophotometric method for the determination of cerium and Tiron (disodium-1,2-dihydroxybenzene-3,5disulfonate) was applied to the determination of cerium in samples which contain uranium and zirconium. The ceriumTiron complex in solutions of pH 8 or greater exhibits an absorption maximum of 500 m mu . This reagent does not react with any other lanthanive element. The interference of iron, uranium, and zirconium was eliminated by extracting these interfering elements with a solution of tri… more
