The dynamic inductance is significant for projectile-borne magnetic flux compression g e n e-rator （MFCG ） design calculation. For the purposes of solving the problem of dynamic inductance calculation ,image current model was applied to the circuit parameters calculation of a projectile-borne MFCG . And the dynamic inductance expression was derived in detail. Subsequently, a numerical computation program of projectile -borne MFCG dynamic inductance was written within deriving process.
