Variation of Blast Pressures at Fixed Distances with Small Altitudes. Buster-Jangle Trials, Nevada Proving Ground.
Abstract
The possibility of variation of peak pressures and time rate of rise to peak pressure at a fixed distance from ground zero led to the experiment described here. Measurements on each of two fifty-foot towers for Buster Shot Easy revealed no definite pattern of variation. That blast pressures and shock arrival times appear to vary as a function of distance of the gauge above ground surface was first observed from records of the Greenhouse trials. On some structures gauges were installed both near the ground and at a vertical distance of about 25 feet. The data generally indicated that the initial pressure responses of those gauge 25 feet above the earth occurred at a time somewhat later than the responses of the ground level gauges. It also appeared that the time rate of rise to maximum pressure was smaller for surface gauges than for those above the surface.
