Abstract: This study demonstrates the use of an Euler-based, unsteady CFD flow solver to model the aeroservoelastic behavior of the Benchmark Active Controls Technology (BACT) wing. For the steady case, results illustrate that a control surface deflection as large as 5° may be modeled without loss of accuracy due to viscous effects. Secondly, the unsteady characteristics of a benchmark wing are addressed showing that flutter prediction agrees well with experimental data over a wide Mach number range. Finally, as a combination of the latter, the development and implementation of a control law into the CFD-based aeroservoelastic model for the purpose of flutter suppression is addressed.
