Comparison of Two Navier-Stokes Methods with Benchmark Active Control Technology Experiments

Two commonly used three-dimensional compressible Navier-Stokes codes are applied to select test cases from an experimental data set on a model known as the Benchmark Active Control Technology (BACT) wing. The BACT test provides data for the validation of aerodynamic, aeroelastic, and active aeroelastic control simulation codes. An overview will be presented of the two Navier-Stokes aeroelastic codes currently being used in an analysis of that data. A collection of results obtained by the two methods will be compared with the BACT experimental data for a wing with a statically deflected spoiler and statically and dynamically deflected aileron. Both methods employ structured computational fluid dynamics flow solvers and continuous surface modeling for the computation of complex moving control surface geometry. Motivation for this work is the development of an integrated computational aeroelasticity and active control simulation capability for the transonic flight regime and validation of that capability using the BACT wing data.
