JET-DRIVEN PROJECTILE FIN Russian patent published in 2008 - IPC F42B10/16

Abstract RU 2321823 C1

FIELD: rocketry, in particular, jet-driven projectiles of salve-fire systems.

SUBSTANCE: the fin has a fairing with wedge-shaped grooves, blades with several wedge-shaped supports, axles and spring. The middle support of the blades is fastened in the fairing groove by means of a close-butt wedge joint, and the rest blade support are installed in the grooves for motion along the blade axis.

EFFECT: enhanced accuracy of the characteristics of fire of the jet-driven projectile by 10 to 25 per cent due to reduced aerodynamic eccentricity of the fin.
