Methodologies for Predicting Dormant Missile Reliabilities

ABSTRACT:This effort focuses on developing a method to aggregate physics based reliability predictions in dormant missile systems. The approach to aggregating these predictions can be similarly applied to non-dormant systems. DfR Solutions will explore dormant failure mechanism models and produce a tool that allows system aggregation of LRU level analysis results. Reliability models for aging solder joint survivability and thermal battery humidity degradation will be developed and combined with existing physics based reliability models in a tool to provide LRU reliability predictions. A systems level tool will then be developed to aggregate LRU reliability predictions at the system level.BENEFIT:Using the resulting tools, dormant system maintenance can be scheduled based on improved information. Commercial systems developers will be able to integrate reliability analysis into their existing model based engineering practices. LRU suppliers will be able to provide customers insight into the expected reliability performance of their products, and contribute in a collaborative way without exposing the intellectual property associated with their design.
