RESPONSE OF AIR BLAST GAUGES OF VARIOUS SHAPES AS A FUNCTION OF PRESSURE LEVEL
Abstract
The nonlinear pressure response of tourmaline air-blast gauges of various shapes has been investigated by comparing peak pressures recorded by the gauges, based upon the extrapolated values of the effective dynamic calibrations at zero peak pressure, with absolute pressures obtained from velocity measurements of shock-front propagation. A similar comparison has been made based upon the static calibrations. Small bare charges were employed in free air. The principal errors involved have been calculated from theoretical considerations at peak pressures of 14 and 29 psi, and the totals of these errors compared with the over-all errors actually recorded.
