Benchmarking of a flux compression generator code

Science Applications International Corporation and the Air Force Research L aboratory are continuing development of a graphical design/simulation code for explosive flux compression generators (FCGs). "FCGSCA" is written in FO RTRAN and Visual Basic and targets the Windows O/S (Microsoft, Chicago, IL) . Basic physics principles and well-known circuit analysis techniques simul ate generator-to-load performance; furthermore, FCGSCA incorporates an arma ture/stator inductance model, a "flux-loss'' model, and a fairly detailed t reatment of the stator winding resistance. FCGSCA includes a capability for modeling transformer coupling and fuze snitching as part of various load c onfigurations; additionally, the user can view overlays of time-history plo ts from one- or two-parameter variation studies. With reasonable costs in f idelity:, this approximation permits quick system-level simulations that ex pedite FCG design and development, Herein, we primarily explain the ease-of -use of the FCGSCA interface and report on some benchmarking against the "R anchito" generator that has been designed and tested by Los blames National Laboratory (LANL).
