Advanced High Temperature Propulsion Materials Research Project: An Update

The goal of this collaborative program within United States Army Research Laboratory (ARL) is to establish a generalized fundamental physics-based approach and probabilistic-based lifing method to extrapolate thermal loading performance and material characterization results from high performance high temperature ceramic materials such as ceramic matrix composites (CMC) based flat specimens and engine component representative specimens. High temperature structural integrity and durability and probabilistic-based lifing assessment is evaluated both analytically and experimentally under thermal shock, thermal cycling, and combined thermo-mechanical loadings. This work aligns with Army's Modernization Priorities Future Vertical Lift and Long Range Precision Fires. This research paper provides the current research of ARL's Advanced High Temperature Propulsion Materials project.
