Effect of Charge Radius
Charge radius affects the detonation velocity of XTX 8003 at a density of 1.53
g/cma, confined in polycarbonate plastic in a hemicylinder configuration, as follows.
D(R) = 7.260[(1 - 0.191 X 1O-z/R) - 2.12 X 1O-4/R (R - O.lll)]
where D = detonation velocity in millimeters per microsecond,
and R = charge radius in millimeters.
The experimentally determined failure diameter in polycarbonate confinement. is
0.36 mm.
