A trial towards integration of EFD (Experimental Fluid Dynamics) and CFD, development of a system called Digital/Analog Hybrid Wind Tunnel, is introduced. The aim of the system is to improve efficiency, accuracy, and reliability of aerodynamic characteristics evaluation in aerospace vehicle developments through mutual support between EFD and CFD. The function of the system consists of optimization of test planning utilizing pretest-CFD calculations, an accurate correction of the wind tunnel wall and support interaction effects through CFD, CFD data refinement based on EFD data, the most probable aerodynamic characteristics estimation based on both EFD and CFD data, database including EFD and CFD data for an identical condition, and so forth. Key technical challenges in the system development are addressed. The detailed system design will be conducted, further identifying the needs and available techniques suitable to the system.
