Ejecta from Single-Charge Cratering Explosions: Volume 1

Description: "Eight high-explosive charges weighing 8 to 1000 pounds were detonated in playa. Each event included 24 to 40 locations of tracer material in the expected crater region. The objective was to obtain data relating the origin of crater ejecta to its depositional location. Resulting data are presented for craters, ejecta areal densities, crater and ejecta mass quantities, tracer dispersion, and an empirical prediction model."

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.

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

A Small-scale Investigation of the Possibility of Constructing Low-Relief Earth-Fill Dams Using Nuclear Explosives

Description: The experiment described herein has shown that the concept of low dams produced by ballistic collision of ejecta from simultaneous detonation of properly spaced parallel rows of charges is a feasible one. Rows of 8-pound charges were buried 3 feet deep with 4-foot spacing between charges. When two such rows of charges were placed parallel and 17.5 feet apart, the maximum height of the "dam" was achieved. The spacing of 17.5 feet between rows corresponds to 4.7 times the crater radius of one 8-p… 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.

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

The Sandia APAR-3G system: Automatic Programming, Recording, and Control for Development and Production Testing

Description: Abstract: The APAR-3G system is an automatic programming, controlling and recording machine which is readily adaptable to a wide variety of automated data acquisition and constrol system applications. It is physically and logically modular to permit the assemby of minimum or maximum capability machines. This system can perform the necessary acquisition and control in a typical factory environment and can generate an output (for data reduction) which is compatible with available computer system… more

Spectrographic Analysis of Plasmajets: Progress Report 2

Description: Abstract: This is the second progress report on the work performed at Sandia Corporation in the use of spectrographic techniques in plasmajet diagnostics. Typical results of spectrographic data from argon and nitrogen plasmajets are included. For the argon jet, the results from line intensity measurements of ionized and unionized atoms generally give good information. However, results from hydrogen line broadening measurements indicate several unexplained discrepancies. For the nitrogen jet, th… more

A Scale-Model Experiment of the Crater Produced Through Terrain of Randomly Varying Elevation by Row Charges

Description: Abstract: "A scale-model experiment was made to check the application of charge spacing rules developed from earlier studies to terrain of randomly varying elevation. Since a prominent possible peacetime use of nuclear explosives is the excavation of a trans-Isthmian canal, the model used was a portion of such a route. The experiment resulted in nearly the desired linear crater dimensions; the spacing rules developed for level trerain give a satisfactory channel when applied to terrain with ele… more

Stress Pulse-Trains from Multiple Reflection at a Zone of Many Discontinuities: a Notation for Machine Solution

Description: Abstract: "Presented in this report is a numerical method by which may be calculated the amplitudes of the trains of pulses that result when a single simple stress pulse encounters a zone of many abrupt discontinuities in a slender rod. The notational scheme employed enables the system of multitudes of individual progagating waves to be studied in terms of analogous number sets which may be mechanically generated. The notational concept and related operational rules, described in this report, h… 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
