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.

Revolutionizing Naval Logistics: The Challenges and Prospect of Metal Additive Manufacturing on U.S. Navy Ships

In 2022, the U.S. Navy installed the first-ever permanent metal AM machine aboard a U.S. naval vessel. This technology is projected to be groundbreaking by reducing resupply logistics and diminishing obsolescence: “For the Navy, the greatest immediate potential is in the less-exotic field of logistics” [1].

What Makes a Simulation Credible? Cost-Effective VV&A in the Systems Engineering Process

The U.S. Naval Air Warfare Center Aircraft Division (NAWCAD) Verification, Validation, and Accreditation (VV&A) Branch has developed and is executing a cost-effective, risk-based VV&A process for models and simulations (M&S) used to support the U.S. Department of Defense (DoD).
