Numerical Simulation Method for Flutter/LCO of Wing/Store Aeroelastic System

摘要：

Flutter and limit cycle oscillation is a very dangerous nonlinear dynamic aeroelastic phenomena for aircraft structure. The coupling method of Computational Fluid Dynamics (CFD) and Computational Structural Dynamics in time domain is the state of the art way to solve aeroelastic problems. Based on the exchange of information between fluid-structure interaction simulation including IPS and CVT method, a CFD/CSD couple solver was investigated. The Goland+ wing/store aeroelastic system was simulated to validate the efficiency of the solver. The simulation results indicate that the CFD/CSD coupled method can capture the flutter and LCO very well.
