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.

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).

Survivability and Lethality of Aircraft in Tactical Environments (SLATE)

Survivability and Lethality of Aircraft in Tactical Environments (SLATE) simulates a two-sided (red and blue) combat for a diverse set of players (air and ground systems) whose functions are shooters, weapons, and targets.  These functions are defined across…
