Yield and Blast Analyses with a Unified Theory of Explosions
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.
