A Surrogate Model to Quantify Uncertainty in Thermal Protection Systems for Hypersonic Weapons

Modeling and simulation are key for the iterative development of thermal protection systems (TPS’s) for hypersonic weapons. In this work, the temperature-dependent flexural strength (FS) of α-SiC ceramic is predicted given Young’s modulus, Poisson’s ratio, and temperature. An artificial neural network (ANN) surrogate model is created to retain property-performance prediction while increasing computation speed.

Attributing Mission Performance to Submarine Subsystems

Submarine design is a multifaceted process requiring extensive effort spanning across various disciplines and organizations. Part of this effort is deciding which missions a submarine is expected to conduct and assessing its efficacy, or mission effectiveness, in those missions via constructive simulation.
