Abstract
This document considers a platform target subjected to a normal impact of explosive products generated by detonating a bare charge in space. It is suggested that the loading impulse may be approximated by the total momentum of that portion of the fluid which impacts at the target. Assuming impulsive dynamic response, and assuming that the ensuing damage is proportional to the kinetic energy imparted to the structure by the blast, we get a particularly simple law; Damage similar to W to the 2nd power/R to the 4th power (W is charge mass, R is range). This model is an idealization of a solar panel (or antenna) extended in a paddle-like fashion from a relatively rigid and massive core structure. It is also shown that this law implies that no advantage can be realized by re-arranging the mass of a single bare charge in a cluster configuration of smaller sub-charges, which would be dispersed and detonated via an idealized 'isotropic' scheme.
