Summary of the Second AIAA Stability and Control Prediction Workshop

This paper documents the setup, execution, and findings of the Second Stability and Control Prediction Workshop (S&CPW2) held at the AIAA SciTech 2025 Forum. The workshop focused on prediction of static and dynamic stability derivatives for the Common Research Model (CRM) at subsonic flight conditions. The static workshop test cases were composed of angle-of-attack and angle-of-sideslip sweeps; the dynamic test cases included roll, pitch, and yaw sinusoidal forced oscillations. Seven organizations submitted computational fluid dynamics (CFD) results to the workshop using a variety of approaches. Wind-tunnel data collected in the NASA Langley 12-Foot Low-Speed Tunnel for a 2.4% scale version of the CRM served as a blind basis of comparison for the CFD predictions. The workshop findings indicate that additional collaborative efforts are needed to help establish best practices for accurate prediction of dynamic stability derivatives.
