Failure Analysis of the M825 Burster Assembly

Abstract

Recent firing tests of the M825 155-mm Smoke round produced an unacceptable number of nonfunctioning rounds. Commonly accepted theories focused on the burster tube housed inside the payload canister as the source of the problem. One possibility was that the burster well was failing or stretching at launch, producing an air gap and thus preventing the ignition of the small burster charge. This report addresses that possibility through a finite element analysis of the critical welded region where the burster tube joins the forward closure plate of the payload canister. It is shown that the burster tube remains basically intact except under one remotely possible circumstance unlikely in these firing tests.
