Abstract

A fuel assisted electromagnetic launcher wherein a payload is contained in a forward portion of a pointed cylindrical launch container and rocket fuel is contained in a rearward portion; and wherein a launch preparation unit in the launcher cools and heats alternate junctions in circular disposed thermopiles around the cylindrical launch container; and wherein electrical coils encased in plastic form a cylindrical barrel. With the coils with spacers in between each containing a photoelectric detector charged by an external D.C. voltage source electrical fields from the coils interact with the electrical fields around the launch container when the launch container is propelled into the cylindrical barrel by ignition of the rocket fuel; the interaction being caused by the magnetic wave field successively generated in the coils as the ablative tip of the launch container approaches each coil and thereby activates thru the photoelectric detector in the spacer a Mos-Fet switch or a similar nano-second switch to open a switch in the D.C. charged coil circuit between the D.C. voltage source and a capacitor connected across the inlet and exit leads of each of the coils.
