Terrain Effects on Shock Waves as Measured Using a 1:1300 Scale Model of Reiteralpe Proving Ground
Abstract
A 1:1300 scale model of the Reiteralpe Proving Ground large blast simulator and nearby countryside was constructed. The terrain was modeled by stacking 2.54 cm layer of plywood that have been cut to match the natural contours of the mountain; the plywood was smoothed over with plaster to obtain realistic natural contours. A model shock tube was machined from steel pipe having a 0.767 cm inside diameter. Tests were performed and measurements recorded at four geographical locations of interest. For the purpose of comparison, the shock tube was placed on a flat surface and blast parameters were also measured. This paper emphasizes the effects of the terrain on the shock wave and also discusses the problems encountered in modeling at small scale, such as scaling of materials from 1:1300 to fullsize, signal-to-noise ratio, mechanical vibrations, and very small positive phase duration. Valid, consistent, and repeatable blast measurements were made within the shock tube and at four field locations.
