Abstract:

An investigation of the primary shock front and Mach Y-stem systems was conducted utilizing decigram explosive charges. Distance and arrival time data of the primary shock front was correlated with that of high yield explosions. A good correlation would indicate the feasibility of conducting laboratory scale tests to obtain information on high yield explosions without the expenditure of time and money involved in large scale field tests. Basic data were obtained form the explosions by photographing the shadow of the shock front system utilizing a Polaroid camera, a microflash unit and a time delay generator. Correlation of the overpressure was excellent for small to moderate distances from the point of explosion, as was the yield comparison. The critical angle of incidence comparison indicated a marked difference between experimental and theoretical values.
