Supercritical Wing Flutter

摘要: Abstract : Transonic methods for correcting subsonic oscillatory aerodynamic influence coefficients (AIC's) based on the Doublet Lattice Method use in flutter and dynamic response analyses of supercritical wings are developed applied to a TF-8A model YC-15II prototype aircraft. The effects static aeroelasticity included evaluated. Reynolds number test results discussed. Correlation improved showed good agreement with results. For two applications included, steady corrections dominated unsteady corrections. In process developing transonic new lifting surface theory (currently two-dimensional) is presented, explored correlated using NLR 7301 airfoil. shock wave motion theory. (Author)
