SDM Dynamic Pitch Damping Derivative. Forced-pitch Mach sweep
This study benchmarks Flow360 for a dynamic-derivative SDM test case by comparing fully transient CFD predictions against wind-tunnel and free-flight reference measurements across Mach 0.4 to 1.1. The setup uses a prescribed forced-pitch oscillation at zero mean incidence, reduced frequency k = 0.0493, and 5 deg amplitude, modeled with a sliding-interface approach to reproduce the motion. The study serves to validate both the accuracy and practical usability of Flow360's native end to end workflow for dynamic stability applications, showing that high-quality transient results can be delivered in an end-to-end automated process suitable for aerospace applications.
