CFD verification and validation (V&V) are fundamental activities of credibility analysis for aerodynamic simulations. Through these activities, a large number of data resources will be generated. How to efficiently manage and utilize these treasures is the key problem for benchmark database. In this paper an operable design of open benchmark database is studied and proposed with emphasis on administration, availability, data reliably, unified data standards and open system architecture. The purpose is to provide a paradigm of aerodynamic open benchmark database for CFD V&V, and to overcome some universal obstacles in current aerodynamic database such as lacks of coordination, continuity and necessary communication. Besides, some recent efforts of credibility analysis for aerodynamic simulations in China are briefly introduced.
