Optimization Design Of Setback Generator For Initiating Explosive Devices

Abstract

This paper describes an optimized design of setback generator based on the smart miniature initiator’s demand for physical power, Through the Hopkinson bar impact experiments, we conducted a comparative study of multiple sets of high overload experiments and concluded that axial magnetized permanent magnets with the homopolar opposite and distribution winding can improve generator’s power generation efficiency to certain degree. When axial magnetized permanent magnets with homopolar opposite and distribution winding are used to assemble the optimized setback generator, it can detonate ignition head consistently at 20000G acceleration.
