Method & Evidence

AimHow can the creation and open sharing of standardized benchmark aerodynamic models facilitate the validation of computational and experimental analysis for high-performance aircraft?
MethodExperimental and Computational Modelling
ProcedureA generic model of a high-performance aircraft was designed with simplifications for manufacturability. This model was then tested in a subsonic wind tunnel, collecting force and moment data. Concurrently, numerical simulations (CFD) were performed. The experimental data was used to validate the CFD simulations, and further simulations explored vortex behaviour and the sensitivity of turbulence models. All models and data were made openly available.
