High-G Ruggedization Methods for Gun Projectile Electronics

Jeff Burd

Abstract:	Design and test methods are presented for ruggedizing electronic assemblies to survive artillery gun fire G-forces. Typical peak set-back accelerations for a 155 mm gun projectile are 15,500 G’s with a 9 msec pulse duration. Highly accurate guidance of artillery shells is now possible due to size and cost reductions in GPS receiver navigation electronics. Processes have been developed to attach components for high rate production at low cost. This report documents both GPS receiver board and demonstration test vehicles designs. Presented are the test program results including the successful designs for MCM’s and crystal oscillators. IEC is a proven leader in high-G electronics ruggedization. The demand for miniaturized gun-hardened electronics will greatly increase in the future to power the military’s autonomous munitions. Test component selection and design of experiment (DOE) testing are critical for a successful high-G ruggedization project.
