Prediction of the Full-Scale Cook-off Response Based on Small-Scale Testing
Agency / Branch:
DOD / NAVY
The objective of this proposed effort is to continue the development of Corvid's existing modeling and simulation framework to provide an innovative methodology used to predict the response of full-scale weapons systems to fast cook-off (FCO) and slow cook-off (SCO). Ammunition presents a special problem where no reliable and inexpensive sub or small scale testing capability has been identified. In order to provide critical insight into scaling relationships, this modeling framework will be supplemented by and aid in the design of novel experiments aimed at linking the violence of reaction seen in full-scale systems to small scale experiments. Our approach to this challenging problem is to utilize our M&S capabilities to evaluate scaling effects of heat transfer and thermal damage processes and expand the models based on first-principles-based reaction processes. Once some of these scaling effects have been established, an innovative experiment leveraging these known relationships will be designed to assess full-scale violence of reaction in a small- to medium-scale apparatus. This proposal includes the steps required to accomplish our goal and a discussion on the existing tools that have been developed to support this type of study.
