Benchmark Supercritical Wing Computations Using CREATE-AV KESTREL and NASA AEROM

The Benchmark Supercritical Wing (BSCW) is a benchmark configuration under eval- uation within the Aeroelastic Prediction Workshops (AePWs). This wing was tested in the NASA Transonic Dynamics Tunnel (TDT) as part of the Benchmark Models Program (BMP) in the 1990s and is expected to be tested again in the TDT in 2026. The data acquired during the BMP tests includes unsteady pressure data and aeroelastic responses at various Mach numbers, dynamic pressures, and angles of attack. At the higher angles of attack, the existence of significant unsteadiness and separated flow results in a challenging case for CFD-based aeroelastic predictions. The AePW workshops have focused on various parts of these BSCW test data and a recent major focus regards the higher angle-of-attack conditions. The NASA AEROM software is applied to this configuration at M=0.8 and several angles of attack to evaluate the capability of the method to capture nonlinear un- steady aerodynamic effects at the higher angles of attack. The AEROM software is applied via the CREATE-AV KESTREL CFD code and AEROM results are compared with results from the CREATE-AV KESTREL solutions.
