Propagation of Strong Explosion in Nonhomogeneous Atmosphere

摘要

A hydrodynamic calculation was made of a strong explosion in a non-homogeneous atmosphere. It was found that after a finite period there occurs a departure of a shock front upward to infinity. It was shown that if the explosion is not strong, a strong shock wave cannot extend down to a distance greater than 16.5 km. The speed and pressure in the extending shock wave, depending upon time, was determined. Formulas of conversion into various energies and heights of explosion are given; the region of applicability of conversion is shown.
