Fired Coilgun Results
1 and 2 illustrate the characteristic surfaces for velocity and
efficiency. Note the difference in the orientation of the axes between
figs 1 and 2. Fig 3 shows the coil current during the entire discharge.
Note that the slight reduction in peak current as delta is incremented
is due to the increasing inductance associated with the projectile
1. Velocity surface with delta and charging voltage as parameters
2. Efficiency surface with delta and charging voltage as parameters
3. Complete coil current pulses for various launch delta.
