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."

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.

Salton Sea Meteorological Instrumentation Test Series, Salton Sea, California, Conducted in September 1959

Description: Abstract: "This report discusses tests conducted to determine the accuracy of meteorological equipment which is used to gather upper air data. Equipment tested was the GMD-2, SMD-1A, GMD-1B, and the WBRT-57. A four-station phototheodolite network was used as a standard for point-in-space determinations."

Experimental Pressure Distributions and Force Coefficients on Block Forms for Varying Mach Number, Reynolds Number, and Yaw Angle

Description: Abstact: "Wind tunnel tests were performed to determine pressure distributions and normal force coefficients on three block forms on mounting planes. The dimension ratios of the blocks were 1:1:1, 1:1:2, and 1:1:4. Results are given for variation in Mach number from 0.066 to 0.8, in Reynolds number from 0.28 x 10(exp 6) to 4 x 10(exp 6), and in yaw angle from 0 to 90 degrees. Results show a Reynolds number independence over the range examined. Windward face force coefficients for a given block … 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 Study of Nevada Test Site Wind Variability

Description: Abstract: "Wind observations collected at Yucca Flat since 1951 are analyzed for timewise variability. Variability functions of altitude, season, wind speed, and vector wind are described. Derived variability parameters are incorporated into calculations of fallout safety probability for NTS operations."

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."

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

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 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.
