According to the recent rapid progress of high performance computing, aerodynamic design methodology based largely on CFD (Computational Fluid Dynamics) is becoming an indispensable tool along with wind tunnel testing. In 1991,TRDI-JDA has started the "CASPER (Cmputational Aerodynamics System for Performance Evaluation and Research)" project together with major domestic aircraft manufactures, MHI, KHI and FHI. The CASPER was installed in 1998. We expect the CASPER to be very useful to develop high performance advanced fighter at the beginning of the 21st century. In this paper, we show evolution and highlights of hardware and software of the CASPER. For the CFD code validation, numerous flow computations of various aircraft and airfoil configurations are carried out on the CASPER and compared well to wind tunnel experiments. Providing CFD data for aeroelastic and flight simulation modules, the CASPER also has the potential for multidisciplinary CFD simulation. Some of our numerical results on the CASPER are presented.
