Grid fins, also known as lattice fins, proposed by Belotzerkovsky et al. They consist of an outer frame which supports an inner lattice of intersecting planar surfaces. Unlike planar fins, grid fins are aligned perpendicular to the flow field to allow the air to pass through the lattice of grid cells. The truss structure formed by the lattice fins is inherently strong, which allows the lattice walls to be extremely thin, reducing the weight and cost. One of the main advantages of grid fins is that, due to their shorter chord lengths, at higher speeds, they generate lower hinge moments than planar wings requiring smaller actuators to rotate them. Additionally, the smaller chord and cascade-like flow reduces the likelihood of stall at high angles of attack relative to conventional planar fins offering increased control effectiveness. To this point, grid fins have found numerous uses on missiles and other endeavors. ]]>
