Abstract:
A stabilization fin for use with projectiles which demonstrates improved aerodynamic stability as a result of unique crosssection and profile. The fin assembly is defined by multiple fins extending radially from a carrier tube. Each fin has a precisely tapered outer profile while the sides incorporate longitudinal depressions. A series of these depressions extend radially along the side of each fin and each depression originates at a point to the rear of the leading edge of the fin profile and terminates at a point ahead of the trailing edge.
Abstract:
A fin assembly for use with fin-stabilized projectiles such as grenades and mortars includes a tail carrier tube with a plurality of longitudinally extending fins projecting radially from the tube, the base or foot portion of each fin being pressfitted into the material of the tail carrier tube. The fins are composed of a material having substantially greater strength than the material of the tail carrier tube, and the foot portion of each fin preferably has an undulated configuration with respect to the longidutinal axis of the fin.
