Abstract : The analysis of particle trajectories measured on Diamond Arc 87 is described and results are presented. Smoke trails were used to obtain particle trajectory data in the primary blast from 1000-lb HMX charges detonated at 36-foot HOB and in the Mach wave at the ground surface in the ideal region. The piston-path method is a new technique in analysis by which all of the physical properties of a blast wave are computed from single particle trajectory measured as close to the charge as possible. Results from the Mach wave region near the ground compare with the gage measurements. Dynamic pressures compare less well. Nearly identical results are found for the two detonations. Keywords: Primary shock; HMX; Mach stem; Particle trajectory; Smoke trail; Photographic image. (JES)
