An analytical technique has been developed which allows the shaped charge designer to estimate the required tolerances in the final manufacturing of the device. Calculations are performed for liner, explosive, and confinement asymmetries which indicate that the rigid tolerances placed on the liner are indeed realistic. The present tolerances on explosive geometry and confinement geometry are also shown to be realistic. However, the results indicate that the explosive loading appears to be a problem in round to round variations. Less than a 2 variations in explosive composition will effect the jet more than a liner asymmetry at its maximum tolerance limit. Graphs, indicating transverse jet velocities as functions of liner position for various asymmetries are presented.
