Analysis of Pressure Drop and Heat Transfer of a Pebble-Bed-Storage Heater for a Hypersonic Wind Tunnel

Description: Abstract: "The pressure drop and the time-temperature variation of the air test medium and heat storage material in a pebble-bed heater (designed for intermittent hypersonic wind-tunnel operation at test section Mach numbers of 4 to 11) are presented."

An Approximate Solution for the Vaporization of Liquid Droplets Formed During Re-Entry Ablation

Description: Introduction: The purpose of this report is to describe a mathematical model which will help solve the ultimate-particle-size problem by estimating the evaporative mass losses during that portion of re-entry when the fuel is in liquid form.

Construction of a Sea-Level, Transisthmian Canal Using Nuclear Explosives

Description: Partial abstract: "This report is based: (1) on information developed in earlier high explosive experiments which determined the optimum spacing and burial depth of charges in a row to produce a channel uniformly wide and deep, and (2) on the Sedan and Danny Boy experiments, which provided data on dimensions of nuclear craters in both soil and basalt rock. This information has been combined with the 1947 route surveys of the Panama Canal company, and estimates have been made not only of the num… more

Craters From Four Equal Charges in a Horizontal Square Array

Description: Craters were observed resulting from square arrays of 64-pound charges at various spacings and depths. The closest spacings yielded craters very like those from single 256-pound charges, while wider spacings yielded craters more or less square in shape and with a mound or pier at the center. Generally, the areas so uncovered were greater than for single 256-pound charges, except for very deep charges. Volumes, too, were enhanced by this configuration by as much as a factor of three. If the same… more

Design and Construction of a Unit for Measuring Metal Skin Temperatures

Description: From summary: This report concerns the theoretical evaluation and experimental development of special thermocouples capable of being accurately located at or near the surface of metal structures to permit measurement of temperature distribution through the strictures.

Estimating Safety Probabilities from Fallout Forecasts for Nevada Test Site

Description: Abstract: "Available data on wind persistence and wind forecasting capability have been applied in estimating the probability of a fallout pattern shifting from an uninhabited safe sector into a populated region. Safety probability is computed from win variability, forecasting accuracy, initial height and particle size of radioactivity landing at a point in the predicted fallout pattern, predicted wind speed, length of forecast period, and safe-sector angular width."

High Explosive Crater Studies: Desert Alluvium

Description: From abstract: Crater dimensions have been determined for 23 explosions of 256-pound spherical TNT charges buried in desert alluvium. As opposed to previous work covering depths of burst as great as 6 feet, the work presented in this report extends knowledge of apparent crater radius and depth to depths of burst as great as 30 feet.

High Explosive Crater Studies: Tuff

Description: Abstract: "Spherical charges of TNT, each weighing 256 pounds, were exploded at various depths in tuff to determine apparent crater dimensions in a soft rock. No craters were obtained for depths of burst equal to or greater than 13.3 feet. It was deduced that rock fragments were sufficiently large that charges of greater magnitude should be employed for crater experiments intended as models of nuclear explosions."

High-Explosive Ditching from Linear Charges

Description: Abstract: "Weights of linear high-explosive charges fired on the Yucca Lake playa of the Nevada Test Site varied from 0.23 to 42.7 pounds per foot. Crater and ditch dimensions and volumes resulting from these shots, fired during the fall of 1959 and spring of 1960, are presented here as a function of charge burst depths. Scaling relationships determined are as expected; i.e., square-root scaling of linear-charge weight per foot for ditch width and depth and a direct linear-charge weight relatio… more

Irreducible Representations of Line Groups: the Dynamics of Polymer Chains

Description: Abstract: "The symmetries of infinite polymer chain molecules are discussed using the concept of line groups. Explicit directions are given for obtaining the irreducible representations of line groups employing the formalism developed for three-dimensional space groups. Line groups containing primitive and nonprimitive operations are discussed. Detailed considerations of the line group Vh are given with specific applications to the polyethylene molecule. Directions for generating symmetry-adapt… more

Re-entry Flight Demonstration Number One (RFD-1): Atmospheric Sciences Support

Description: Abstract: Data from the atmospheric sciences support systems for RFD-1 on May 22, 1963, at Bermuda Island, are presented. These data were taken for purposes of later analysis of the ballistic performance of the re-entry vehicle and of the heat transfer mechanisms within it, and for studies of the motion of ablated particles in the atmosphere.
