Final report -- PT-105-548-A, The effect of masonite burnout on shield attenuation properties

Description: In a previous study it was determined experimentally that heat deterioration, or burnout, of the shield masonite is more severe than radiation damage under existing and proposed operating conditions. Higher shield temperatures, which are expected to result from increased power levels, fringe enrichment, and higher graphite temperatures, will markedly increase the rate at which the masonite burns out. The laminated iron-masonite biological shield will lose, as a result of burnout, the hydrogen a… more

Summary report on Columbia University heat transfer studies

Description: Experimental investigations were undertaken at Columbia University to determine the heat transfer and fluid flow characteristics of fuel elements for the Savannah River reactors. Primarily the tests simulated quatrefoil operation, but a number of tests directly applicable to the operation of extended surface fuel elements were performed. Data books were published in which the experimental data are tabulated.

Reduction of the amount of dichromate added to pile cooling water. Final report, PT-105-542-E

Description: Sodium dichromate has been tested for use as a process water corrosion inhibitor at a concentration of 0.5 ppm. The test was conducted by operating one half of D Reactor with 0.5 ppm while the other half operated at the normal concentration of 2 ppm sodium dichromate. A concentration of 0.5 ppm was found to be as effective a corrosion inhibitor as the normal concentration of 2 ppm except under one very important set of circumstances. If the reactor process tube ribs were previously worn or corr… more

A Continuous Electrolytic Process for the Production of Beryllium Metal

Description: A brief description of the process is given, and details of work over a three-year period are summarized. The continuous production of Re metal by low- temperature fused salt electrolysis into a continuously circulating Hg cathcde has been demonstrated. The product is amenable to direct hot pressing or to powder preparation by distilling off the Hg. The production of pure BeCl/sub 2/ in good yield by direct chlorination of BeO has been demonstrated. The production of pure BeCl/sub 2/ in good yi… more

Low-Speed Investigation of the Effect of Small Canard Surfaces on the Directional Stability of a Sweptback-Wing Fighter-Airplane Model

Description: Memorandum presenting a low-speed investigation in the free-flight tunnel to determine the effect of small canard surfaces on the directional stability of a fighter-airplane model with an aspect ratio of 3.4 and a 42 degree sweptback wing. The canard surfaces were found to be generally ineffective at angles of attack below 20 degrees.

An Airborne Simulator Investigation of the Accuracy of an Optical Track Command Missile Guidance System

Description: Memorandum presenting an airborne missile simulator used to represent visually the predicted flight behavior of the Navy XASM-N-7 Bullpup air-to-surface missile, which is guided along the line of sight to the target by bang-bang radio signals controlled by the pilot of the launch airplane. Quantitative response measurements showed that the simulator gave a good representation of the trajectory and control characteristics predicted for the Bullpup missile, and the simulation appeared plausible t… more

Summary of NACA Research on Afterburners for Turbojet Engines

Description: Report presenting a summary of NACA research on afterburners for turbojet engines during the past 5 years. The references present over 1000 afterburner configurations and about 3500 hours of operation. The report covers the following topics: burner-inlet diffusers, fuel-injection systems, flameholders, combustion space, combustion instability, starting and transient performance, effects of diluents, and burner-shell cooling.

Preliminary Investigation of the Static Longitudinal and Lateral Stability Characteristics of a 1/20-Scale Model of the McDonnell F4H-1 Airplane at Mach Numbers of 1.59, 1.89, and 2.09

Description: Report discussing testing on the drag, longitudinal stability, and lateral stability characteristics of a model of the McDonnell F4H-1 airplane. The minimum drag coefficients, neutral point, horizontal-tail-incidence range, static directional stability, and effective dihedrals are presented.

A theoretical and experimental study of planing surfaces including effects of cross section and plan form

Description: A summary is given of the background and present status of the pure-planing theory for rectangular flat plates and v-bottom surfaces. The equations reviewed are compared with experiment. In order to extend the range of available planing data, the principal planing characteristics for models having sharp bottom surfaces having constant angles of dead rise of 20 degrees and 40 degrees. Planing data were also obtained for flat-plate surfaces with very slightly rounded chines for which decreased li… more

Investigation at Mach numbers of 1.41, 1.61, and 1.82 of two variable-geometry inlets having two-dimensional compression surfaces

Description: Report presenting one-tenth-scale models of two inlet configurations of fighter-type aircraft have been tested in the 4- by 4-foot supersonic pressure tunnel. The pressure-recovery and force characteristics of the inlets were determined as a function of mass-flow ratio, angle of inlet compression, angle of attack, and Mach number.

Jet effects on base and afterbody pressures of a cylindrical afterbody at transonic speeds

Description: An investigation of the effects of jet nozzle geometry, size of base annulus, and base bleed upon the base and afterbody pressures of a cylindrical afterbody at transonic speeds has been conducted. Sonic and supersonic conical nozzles with jet-to-base diameter ratios from 0.25 to 0.85 were investigated with a cold jet at jet total-pressure ratios up to approximately 8.0 through a Mach number range from 0.6 to 1.25. Base pressure coefficients of about -0.55 were measured for the sonic nozzles at… more
