Keywords: small disturbance navier-stokes equations, computational fluid dynamics, aeroelasticity

For transonic production aeroelastic analysis the small disturbance Navier-Stokes method FLM-SD.NS was shown to be an efficient and yet accurate alternative to the corresponding dynamically fully nonlinear Reynolds-averaged Navier-Stokes method. FLM-SD.NS is employed to novelly investigate unsteady aerodynamic cases of a fighter-type delta-wing performing harmonic pitching oscillations.
