A Reduced Order Model for Aeroelastic Response Prediction to Continuous Turbulence Encounter including CFD Aerodynamics

摘要

In this paper a frequency domain Reduced Order Model (ROM) to compute the aeroelastic response of a free flexible aircraft flying through continuous turbulence while including high fidelity aerodynamics is presented. It is based on the correction of the unsteady Aerodynamic Influence Coefficient (AIC) matrices. Simulations on both rigid and flexible aircraft have been carried out and the results have been validated against full order time domain simulations for a representative transonic case.
