AN INVESTIGATION OF THE AERODYNAMIC CHARACTERISTICS OF SUPER- SONIC WRAPAROUND FIN MISSILES USING NUMERICAL SIMULATION AND WIND TUNNEL EXPERIMENTS

An extensive experimental investigation has been conducted to study the aerodynamic characteristics of wraparound fin missiles. In the first step, the model of a standard wraparound fin missile has been tested in the Imam Hossein trisonic wind tunnel. The tunnel has a test section of 60 by 60 by 140 cm. The experiments were conducted in the range of mach numbers from 0.4 to 2.2 and at angles of attack between -4 to 10 degrees. The results obtained in these experiments included the longitudinal coefficients, which have been compared with those obtained of NASA wind tunnel as well as an engineering code. Comparisons show good agreement with other experimental and engineering results. Further more numerical code is being developed to solve the flowfield around the same configuration. This code will be ready to use in the near future.
