For example, at a scaled distance of 1 m/kg^(1/3), Pr is approximately 1,500 psi. At 3 m/kg^(1/3), Pr drops to 200 psi. This non-linear decay is why accurate software is critical.

The goal was simple: create a rapid, hand-calculation method to estimate peak overpressure, impulse, and time of arrival for airblast from high explosives (TNT equivalent). Unlike complex computational fluid dynamics (CFD), Conwep uses empirical curve fits derived from thousands of live-fire tests.
