The subiteration algorithm of the Navier-Stokes fluid equations is constructed based on the LU-SGS scheme and the subiteration formulation is applied directly to the structural equations of motion in generalized coordinates. In the flutter calculation, a modified grid deformation approach that maintains the grid quality even under large deflections and rotations has been applied. Results are presented for the AGARD 445.6 standard aeroelastic wing configuration over subsonic to supersonic Mach number range. Predictions of flutter points are compared with experimental data and with simulations previously reported. The effects of grid resolution and time-step sizes are also investigated., 資料番号: AA0032819050, レポート番号: NAL SP-53}, pages = {291--296}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {Transonic aeroelastic calculation with full implicit subiteration and deforming grid approach}, volume = {53}, year = {2002} }
