REFLECT-4 Code Computations of 40 KT Nuclear Blast Waves Reflected from the Ground for Four Heights-of-Burst. Volume 2. Detailed Data and Plots.
Abstract
The REFLECT-4/FAB-2D two-dimensional hydrodynamic computer codes were used to compute the blast flow characteristics for 40-KT nuclear bursts reflected from the surface of the earth in a non-homogeneous atmosphere for four heights of burst. Detailed results are presented for overpressure, dynamic pressure, positive impulses, positive pressure durations and arrival times for 40-KT bursts in a standard non-uniform atmosphere for heights of burst of 1026, 1710 and 2052 feet (scaled heights of burst of 300, 500, and 600 ft/KT to the 1/3 power) down to ground peak overpressure levels less than 0.4 psi. In addition, results are presented from a very high resolution run for a 40-KT burst at 1368-ft HOB (400-ft SHOB) for ground ranges through the transition range. The numerical results are generally in agreement with nuclear test results and indicate a possible need for revisions of present height-of-burst charts. Effects of small heights above the ground on the overpressure and dynamic pressure blast environment are discussed. Volume I of this report summarizes the computed data obtained. Volume II presents detailed tabular data and time histories of overpressure and dynamic pressure at the ground and the associated impulses.
