Kurzfassung
In this paper the multi-disciplinary simulation of unsteady flight maneuvers is carried out using reduced-order models (ROM) based on Reynolds Averaged Navier-Stokes (RANS) solutions. The analysis of gust encounters on the NASA Common Research model (CRM), a typical transport aircraft configuration, at transonic speed is conducted for two approaches employing time-linearized CFD and CFD-corrected DLM. The results are compared to nonlinear CFD and DLM simulations. The numerical prediction of gust loads requires the coupling of the disciplines aerodynamics, structural dynamics and flight mechanics. The aeroelastic coupling is realized in the frequency domain and in the time domain in terms of generalized coordinates employing a fluid-structure feedback loop.
