An experimental program was conducted to determine blast pressures, total impulse, and catchup times of shock waves generated by sequentially detonating two explosive charges. The parameters varied in this experimental series included charge spacing, time delay between detonations, and orientation of the charges with respect to two right-angle blast lines. Peak overpressure at a given point in the blast field around the charges was noted when the two shock waves just coalesced at that point. Peak pressure from two sequentially detonated charges also was compared to a total weight equivalent one-charge detonation in particular directions or orientations.
