Abstract:

Yield is the most significant single number measured on any explosion because all effects -- sympathetic reactions, fragments, blast damage -- derive from it. UTE offers the only adequate way to relate all explosions non-ideal, any media, over all ranges in air, underwater, underground, confined spaces, heavy cases etc. The Form Factor and Lead Time are new extensions intended for safety analyses. A key idea in the form factor is to define average energy density in the blast wave relative to the peak value at the shock it is the tacit assumption in scaling now. Lead Time means the difference in TOA between a sound signal and a shock wave it scales, is a sensitive measure of yield and is nearly constant at long range. Applications include absolute measure of prompt and delayed yields for blast, sympathetic reactions, fragments, propellant yield, surface effects, analysis with sparse data and simplified instrumentation.
