533Shaped Charges
Equations 18.17 through 18.27 are typically solved by computer to determine the formation
parameters and describe the jet formation. It is beyond our scope to discuss the coding of
the equations. Results of this model are shown in Ref. [1].
Problem 1
A conical-shaped charge liner is to be fabricated from copper and lled with CompositionB
as the explosive. The thickness of the liner is to be 0.1 in. and the half-angle, α, is to be 45°.
The length of the liner is 3 in. and the charge OD is 7 in. Determine the following using
the Birkhoff et al. theory:
1. Mass of the jet
Answer: m
j
= 0.302 [lbm]
2. Mass of the slug
Answer: m
s
= 0.990 [lbm]
3. Velocity of the jet
Answer: V
j
= 4752 [m/s]
4. Velocity of the slug
Answer: V
s
= 1 ...
