摘要

Flowfield solutions of a projectile with wraparound fins have been computed in a supersonic region with a time-marching, three-dimensional Euler equation. The roll moment coefficients were computations show good field solution and compared with the experimental results. The roll moment coefficient computations show good agreement with the experimental measurements for various flight Mach numbers. This shows that the Euler equa- tions can give comparably accurate solutions when computing the roll moment of wraparound fin configurations.
