Improved Setback Generator
Abstract
This technical report summarizes the design, development and test of a setback generator and its associated energy storage module. The generator, measuring 1.5 inches in diameter and 1.2 inches in height, has produced over one million ergs of energy in laboratory tests. This energy is stored on a capacitor bank (energy storage module) to serve as a power source for an artillery fuze. The contract specifies a minimum energy requirement of 675,000 ergs. The setback generator developed on this program provides a unique feature in that it extracts energy from a magnetic field through a reverse saturation cycle. An important result of this feature is that the low magnetic forces between the core and its housing allowed the core assembly to release at very low acceleration input levels. This makes a generator of this design particularly attractive for use in rocket and mortar fuze applications. Laboratory and field tests have demonstrated that the generator of this general design can produce nearly 400,000 ergs in a 30g setback environment. Test units which were fabricated were evaluated under both laboratory and gun launch environments. The results of these tests confirmed the output predicted from analytical studies to be consistent with those results demonstrated in the laboratory, but greater than those demonstrated in ballistic firings. The inconsistency is expected to be resolved following ballistic tests on the 20 deliverable units under this contract.
