Kurzfassung
This paper provides an overview about the time-linearized analysis of motion-induced and gust-induced airloads with the next-generation CFD solver framework CODA. Two approaches for obtaining time-linearized airloads are presented: the linear frequency domain solver which solves the linearized discretized RANS equations for the time-linearized response, and a system identification method which obtains the time-linearized aerodynamic response from nonlinear time-accurate simulations. Both methods are applied for typical two-dimensional and three-dimensional test cases including the NACA 64A010 airfoil, the AGARD LANN wing and the NASA CRM transport aircraft model employing pitching oscillations and sinusoidal gust encounter. By comparison of both approaches, the consistent and accurate implementation of the LFD solver and the time-accurate integration scheme in the CODA framework for time-linearized forced motion and gust encounter simulations is verified.
