Transonic and supersonic flutter characteristics of a wing-box model with tip stores

Angle-of-Attack Effect on Transonic/Supersonic Aeroelasticity of Wing-Box Model

“…The aerodynamic root chord length is 160 in., and it is the same structural model used in Ref. 6, except for the tip launcher and missile. The full computationalmesh used is a 75.x/ £ 32.y/ £ 40.z/ grid, where 50 chordwise and 22 spanwise grid points were used on the aerodynamic wing surface.…”

“…The computed steady aerodynamic results for rigid and deformed shapes of the model are presented and compared. Also, detailed dynamic aeroelastic responses are computed using a coupled time-marching method based on the effective computational structural dynamic (CSD) and computational uid dynamic (CFD) techniques, 6 which are similar to those used in Ref. 5 of utter boundary due to the change of initial angles of attack are also compared for several Mach numbers.…”

Multidisciplinary Optimization of an Aircraft Wing/Tip Store in the Transonic Regime

“…However, no optimization was conducted with the dynamic aeroelastic constraints for which the tip store is attached. Kim and Lee [7] performed aeroelastic analyses in the transonic and supersonic flow regions using a CFD technique (TSD3KR) for computing the unsteady aerodynamics in conjunction with MSC/NASTRAN for the flutter analysis of a wing with a tip store. They conducted a matched-point flutter analysis to obtain the flutter solutions in both the frequency and time domain.…”
