O-192 Mitigation Technologies for Propulsion Applications

During the last decades, strong efforts have been made by the IM community to decrease the reaction level of munitions when submitted to standardized tests considered representative of operational threats such as fast and slow heating, bullet and fragment impacts, sympathetic reaction and shaped charge jet impacts. To do so, numerous studies were undertaken to identify the reaction mechanisms occurring within the munitions and, in a second step, to decrease the reaction level of the solicited munitions.

As a consequence, many mitigation systems were studied and developed to achieve this goal, either to mitigate the stimulus applied to the tested item, or to avoid any violent reaction of the tested item or, if a violent reaction is unpredictable or impossible to avoid, to decrease its effects in the surrounding environment.

A review of mitigation techniques available for rocket motors was undertaken last year within the frame of an MSIAC intern project. This work revealed a massive amount of documents that were analyzed, sorted and released to the community through a limited MSIAC document, L-199. This document aims to share the major outputs of this study with the IM community, and to present the forthcoming works related to this topic.
