Abstract:

The nonlinear pressure response of tourmaline air-blast gauges of various shapes to one-pound spherical pentolite charges 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. The peak pressure range of 10 to 80 pounds has been covered. The response errors involved have been calculated from theoretical considerations, and the totals of these errors compared with the recorded errors. A comparison has been made with the results previously reported from one-eight pound spherical pentolite charges.
