mLIFE™ - Integrated Rocket Motor Life Prediction Software System

Under a Phase II SBIR contract with AMRDEC, Impact Technologies, LLC has developed an integrated solid propellant life predication analysis tool, mLIFETM. This tool not only integrates the many diverse methods of energetic life prediction, such as thermal stress-induced creep and linear damage accumulation, but adds additional models using finite element analysis, nonlinear damage accumulation, chemical process effects, and probability theory. To manage this wide variety of methods and models, the software is designed in a tiered modular format that allows updated modules (lifing models, fusion algorithms, data management libraries, etc.) to be easily integrated and/or fused with existing predictions along with computational distribution. Other features include an intuitive graphical interface that combines tools for managing data (both inputs and outputs), visualization, and report generation. In addition, this technology is applicable to private sector single-shot devices, such as vehicle airbags, that must work even after long periods of time under varied environmental conditions. Other critical single-shot devices, such as ejection seats, emergency shutoff valves, and torpedo squibs, will also benefit from these improvements in the modeling and management of data and predictions.
