Abstract:

The effects of very small, low frequency, perturbations to steady transonic flows are investigated for two-dimensional flows described by the small perturbation equation. A method that allows one to account for shock wave motions due to arbitrary, but small, unsteady changes in the boundary conditions is described. Both harmonic and indicial responses may be calculated. Time-linearized results for transonic flow past an NACA 64A006 airfoil experiencing harmonic motions in one of several modes are presented.
