Effects of nonideal surface on airblast from one-megaton yields. Final report

Technical Report ·
OSTI ID:6079692
Hull hydrodynamic computer-code calculations were performed of 1-MT surface bursts and air bursts at 500, 750, and 1000 feet heights of burst (HOB). Calculations were performed for both an ideal ground surface and a nonideal surface (with a hot layer of air above the ground surface). The properties of the hot layers of air were defined by a fit to sound-speed data from several Nevada events. The nonideal surface burst began to develop a precursor at 1000 psi. All air bursts showed strong precursor effects. The heights of burst were low enough to produce hydrodynamic precursors, due to jetting above the ground, even without a hot layer of air. The addition of a hot layer increased the extent, effects, and duration of the precursor.
