Impact of External Environmental Factors on Minuteman III Inertial Guidance System (NS-20) Failures

Abstract

This study is a preliminary search to determine if a relationship exists between Minuteman 3 Guidance System (NS-20) failures and the external environmental factors of temperature, wind speed, wind direction, humidity, and barometric pressure. Multiple regression analysis was used to determine what degree of relationship, if any, existed between NS-20 failures and several combinations of environmental factors. The search was extended to determine whether or not a relationship existed between external environmental factors and the failure of subcomponents of the NS-20, i.e., the Digital Computer Unit (DCU) and the Pendulous Integrating Gyroscopic Assembly (PIGA). Environmental conditions existing at the time of failure and prior to the time of failure were included.
