Analysis of the evaluation indexes and requirements of the wind tunnel based virtual flight testing for flight control systems

In order to determine the flight control system (FCS) performances which the wind tunnel based virtual flight testing (VFT) can evaluate, and lay the foundations for designing the VFT evaluation methods, the evaluation indexes of VFT and the requirements of VFT evaluation methods for FCSs were analyzed. Firstly, according to the features of VFT, the flight performance indexes and flight quality indexes of FCSs which VFT can evaluate were proposed, and the evaluation capability differences among the VFT, hardware-in-the-loop simulation (HILS), and flight tests were compared. Then, the differences of evaluation results between VFT and free-flight caused by the features of VFT were compared. Lastly, from the aspects of testing, data processing, and the performance determination, the specific requirements of the VFT evaluation methods for evaluating the above indexes were proposed. And the evaluation requirement differences among the VFT, hardware-in-the-loop simulation (HILS), and flight tests were compared.
