A modular aluminum-composite energy storage inductor has been designed and tested for use in electromagnetic launch applications. The Brooks coil inductor has a storage capacity of 5.0 MJ and weighs less than 1000 pounds. Finite element stress analysis has been developed for axisymmetric coils which can be scaled up for any size coil or current. Test results are presented. By combining a high performance storage inductor with the appropriate prime power supply and opening switch a very compact and efficient pulsed power source can be constructed. Inductive energy storage is particularly attractive in EM launcher applications where a constant current source is descirable. The critical performance parameters of any storage inductor is the L/R time constant, Tau, and the maximum energy storage capacity both of which do not directly depend on the coil inductance. For most applications it is desirable to maximize these parameters with respect to coil weight.
