Fuel-Air Explosive Nuclear Airblast Simulator. Investigation of Secondary Waves.

Abstract

The small-scale DNA fuel-air explosives airblast facility (1/4 T nuclear airblast equivalent) was modified to increase pressure and photographic instrumentation. Additional preparations were undertaken to enable tests to be conducted under a variety of conditions thought to be responsible for secondary shock wave formation. A number of experiments were conducted. These indicated that: (1) detonation was marginally initiated in the fuel-air clouds; (2) cloud shape did not greatly influence the airblast except in the immediate vicinity of the cloud; (3) transverse moving waves were not present external to the cloud boundaries; (4) fuel distribution non-uniformities within the cloud appear to produce local secondary explosions.
