Design and performance of a multi-stage cylindrical reconnection launcher.

摘要

A multi-stage, cylindrical, reconnection launcher is being tested to demonstrate electrically-contactless, induction-launch technology for solenoidal coil geometry. A 6-stage launcher system is being developed to accelerate a 5 kg mass from rest to 300 m/s with a stored energy of (ge)200 kJ per coil stage. This launcher will provide data for model verification and the engineering basis for proceeding with larger multistage systems. This paper describes the design of the multi-stage, discrete-coil launcher. Integration of coils, projectile, power systems, and real-time fire control are discussed. Results of multi-stage firings are presented. 6 refs., 10 figs.
