Paper Abstract

To describe all the physical properties in blast waves at any fixed point it is necessary to independently measure the time variation at that point of at least three of the physical properties. High-speed photography of smoke tracers established adjacent to the explosive charges was used to measure the particle trajectories in blast waves from a large number of air burst and surface burst explosions. To describe the trajectory of a spherical piston the trajectory of a smoke tracer which was initially close to the charge was used in a numerical simulation. The trajectories of massless particles were calculated at initial positions identical to those of the other flow tracers in the experiment.
