TL;DR: In this article, the CAP-TSD code was applied to the active flexible wing windtunnel model for prediction of transonic aeroelastic behavior, where a semispan computational model was used for evaluation of symmetric motions, and a full-span model was employed to evaluate antisymmetric motions.
Abstract: The CAP-TSD code, developed at the NASA Langley Research Center, is applied to the active flexible wing windtunnel model for prediction of transonic aeroelastic behavior. A semispan computational model is used for evaluation of symmetric motions, and a full-span model is used for evaluation of antisymmetric motions. Static aeroelastic solutions using the computational aeroelasticity program-transonic small disturbance, are computed. Dynamic (flutter) analyses are then performed as perturbations about the static aeroelastic deformations and presented as flutter boundaries in terms of Mach number and dynamic pressure. Flutter boundaries that take into account modal refinements, vorticity and entropy corrections, antisymmetric motions, and sensitivity to the modeling of the wingtip ballast stores are also presented and compared with experimental flutter results.
