CASPERによる空力特性評価の現状と展望

According to the recent rapid progress of high performance computing and numerical algorithm, a CFD-based aerodynamic design methodology is becoming an important tool with wind tunnel testing. The 3rd Research Center, TRDI-JDA has implemented the development and performance tests a CFD-based design system CASPER (Computational Aerodynamics System for Performance Evaluation and Research), with major domestic aircraft manufactures until March 2001. In this paper, mainly shown is part of aerodynamic and aeroelastic computed results obtained in performance tests. Actually, for the code validation, various types of aircraft and airfoil configurations are computed using the CASPER and compared well to wind tunnel testing data and other computed results. In addition, as an example of CFD multidisciplinary simulation providing the CFD data obtained in its aerodynamic characteristic module, the aeroelastic simulation can be normally performed. The CASPER can be expected to be powerful tool for conceptual and basic design stage of advanced aircraft at the next generation.
