Using state-of-the-art physics-based models, Veracity’s scientists in Brigham City, UT, are well along in developing an innovative approach for reducing uncertainty and error in modeling service-life estimates of solid rocket motor (SRM) propellant. The goal is to reduce uncertainty by a minimum of 10 percent, resulting in higher confidence in the reliability of SRM weapons systems. To predict service-life estimates for individual motors within a weapons system’s fleet, sophisticated analysis tools must be practical to use and must perform consistently. Veracity’s SRM Modeling Toolset allows large numbers of rocket motors and large amounts of data to be analyzed efficiently. The toolset simplifies the use and integration of advanced models and provides a consistent interface for analysts, enabling innovative methods for achieving accurate service-life prediction.
This project supports the Air Force Research Lab (AFRL), Rocket Propulsion Division, Edwards AFB. Veracity recently completed Phase II of the project.
Aging and Surveillance
At Veracity we employ state-of-the-art analysis tools for aging and surveillance (A&S) of energetic materials. We support our customers throughout the A&S life cycle:
- failure mode and effects analysis (FMEA)
- test plan generation
- data processing
- chemical evolution modeling
- safe-life and service-life calculations
- reliability modeling
At each phase we work closely with material experts and engineers to ensure current scientific understanding and product familiarity.
We create advanced material models for energetic materials. Our experience includes creating models for polymeric binders, particulate reinforcement, and particulate agglomeration. We provide greatest value by quickly prototyping and verifying material models and then implementing them in production-ready code. At Veracity, we build models using Python, C++, and various other programming languages. We also have built models for integration into third-party analysis tools, such as user-defined mechanical behavior subroutines (UMAT) for Abaqus (finite element analysis tool).
