Abstract:

An experimental investigation was conducted of the effect of simulated nuclear blast waves on fires, simulating those that would be started in urban interiors due to thermal radiation that would have emanated from a 1 Mt-yield weapon assumed to be the source of the simulated blast. Blast waves in the range 1 to 5 psi nominal overpressure propagated through windows in a non-failing wall into full-scale test rooms furnished as typical living room, bedroom and office occupancies. The fire-blast interaction, in various combinations of occupancy and incident overpressure, and for non-failing walls having two different window areas, was documented by conventional and high-speed motion picture photography, and by post-test photography and recorded observations.
