ICBM Overtest Technology. Volume I

Abstract

This is the final report on the ICBM Overtest Technology Program which was performed by Hercules Incorporated for the Air Force. The primary objective of the program was to develop overtest technology for the prediction of ICBM motor service life. An important secondary objective was to make predictions of the M57A1 motor life. The most critical failure modes were shown by analysis and verified by analog subscale and full-scale motor tests to be wing slot cracking and aft centerport debonding in response to the ignition transient. Event gages were developed for detecting time of failure and to verify gage response. Since no aging effects on the grain were determined, an indefinite service life was projected for the Minuteman 2 Stage 3 motor. A manual of recommended practice for incorporating overtest concepts in surveillance programs has been prepared.
