INSTRUMENTS FOR MEASUREMENT OF DUSTY AIRBLAST EFFECTS IN HIGH OVERPRESSURE REGIONS

Abstract

Instrumentation has been developed for the measurement of dynamic pressures and drag forces in high velocity, high pressure airstreams which are laden with dust. The instruments are intended specifically for the high overpressure regions (up to 500 psi) during atmospheric tests of nuclear weapons over desert surfaces. The research program included the design and construction of: (1) four total pressure probes (SRI-MAD gages) capable of measuring almost independently the total pressure of the gas phase and the momentum flux of the suspended dust, (2) four total drag probes to measure directly the drag force on a cylinder, (3) four dust sampling devices to obtain representative samples of suspended dust for particle size distribution analyses and (4) a surface shear gage to measure the magnitude of airblast induced shear stresses in the soil.
