Application of Navier-Stokes simulations for aeroelastic stability assessment in transonic regime

摘要: Aeroelastic stability analyses in transonic regime require the adoption of accurate aerodynamic models, such as those based on Euler or Navier-Stokes equations, to model physics associated with shock waves. To transfer application this type from academy industry, it is necessary verify if technology mature enough be implemented without using specialised pieces software. This paper presents a numerical strategy for solving aeroelastic fluid-structure interactions (FSI) problems partitioned procedures ''black-box'' CFD software solution flow field. The focuses three elements: outline test procedure linearised reduced order models (ROMs) quickly locate instability points; novel interface scheme high degree flexibility, adapt structural initially not developed FSI interactions; fast, reliable and easy use grid deformation schemes. purpose show how robustness results ease can achieved limited efforts.
