Analysis of the wind tunnel based virtual flight testing system and key technologies for the evaluation of flight control systems

Based on the deficiencies of the traditional flight control system (FCS) evaluation methods, the advantages of wind tunnel based virtual flight testing (VFT) for evaluation of FCS are analyzed. According to the common constitution of attitude control loop and guidance control loop used by FCS, the test system and working principle of VFT for FCS evaluation are presented. And the main differences between VFT system and HILS system are analyzed briefly. The key technologies of VFT for FCS evaluation are analyzed, including VFT evaluation methods, aircraft model design technique, FCS modification technique, and model support technique.
