Abstract :
Compulsators are power sources of choice for use in electromagnetic launchers and railguns. These devices hold the promise of reducing unit costs of payload to orbit. In earlier work the author had calculated the current distribution in compulsator wires by considering the wire to be split into a finite number of separate wires. The present work develops an integral formulation of the problem of current distribution in compulsator wires which leads to an integro-differential equation. Analytical solutions including for the integration constants are obtained in closed form. The analytical solutions present a much clearer picture of the effect of various input parameters on the cross sectional current distribution and point to ways in which desired current density distribution can be achieved. Results are graphically presented and discussed with particular reference to a 50 kJ compulsator in Bangalore. Finite element analysis supports the results.
