The effects of grid pattern on aerodynamic characteristics of grid fins have been investigated experimentally. The fins are designed to have the same area for each and total grid cell, and mounted on four individual fin-balances near the aft end of a body. Test results show that the effects of grid pattern on grid fin aerodynamic characteristics are smaller than expected in subsonic and supersonic flow.
