Keywords: grid fins, planar fins, comparison, control surface

This paper presents a study of aerodynamic characteristics of grid fins and conventional fins which have been used on missiles and bombs to control their trajectory. Simulations successfully predicted the flow behavior over the grid fin and showed their improved control effectiveness and aerodynamic characteristics over the conventional fin.
