ABSTRACT:
An electro-expulsive system 20 has one or more overlapped conductors OC1-OCN each comprising a flexible ribbon conductor 32 which is folded back on itself. The conductors are embedded in an elastomeric material 33. Large current pulses are fed to the conductors OC1-OCN from power storage units 1-N. As a result of the antiparallel currents I and I', the opposed segments of a conductor 32 are forcefully separated and the elastomeric material is distended. Void 34 in the elastomer aids the separation of the conductor segments. The distention is almost instantaneous when a current pulse reaches the conductor and the distention tends to remove any solid body on the surface of the elastomeric material.
