ON THE ORIGIN OF SHOCKWAVES FROM CONDENSED EXPLOSIONS IN AIR. PART 3. AIRSHOCK RADIATION FROM SMALL EXPLOSIONS AT SEA-LEVEL CONDITIONS
Abstract
Photographic and spectral observations have been made of the earliest stages of HE explosions. Strong (in the neighborhood of Mach number = 20), non-luminous airshocks have been photographed as close in as 1/2-charge radius from the explosive surface. The present results support earlier observations on the existence of a transmitted airshock created by the detonation shockwave. The spectra obtained show no evidence of the expected shock-air species. Identification of the spectral features suggests that the intense early light of an explosion is created within the fireball by a wide range of chemical species requiring from about 2 to 20 ev for excitation.
