The small disturbance Navier-Stokes method FLM-SD.NS serves the prediction of unsteady aerodynamic loading in the transonic speed range due to a simple harmonic excitation. The flow-topological versatility and the computational efficiency gain with respect to its unsteady Reynolds-averaged Navier-Stokes counterpart FLM-NS is substantiated by means of pitching- and flap-oscillation test cases of the NASA Clipped Delta Wing. These feature shocks of diverse strength, as well as a leading-edge vortex.
