Temperature measurement of shocked copper plates and shaped charge jets by two-color ir radiometry

Abstract

A two-band ir radiometer was used to measure the residual temperature of thin copper plates shocked with various explosives. Evidence indicates that a large shock-induced emittance has been largely compensated, and the results agree with other experiments but not with hydrodynamic theory. Preliminary results for the temperature of a copper shaped charge jet in flight yield a temperature of 432 °C.
