Beschreibung
Zusammenfassung:FIELD: rocketry, in particular, aerodynamic fins of jet projectiles. ^ SUBSTANCE: the aerodynamic fin has a fairing with grooves. Foldable bent blades are placed in the fairing. The blades are made in the form of plates with a trapezoid cross-section. The blades are bent in radius making up 0.4-0.5 of the projectile caliber on a section equal to 0.6-0.8 of the blade height. The blade base thickness-to-its end thickness ratio makes up 1.8-2.0. The number of the supporting surfaces and engageable springs makes up at least two per blades. ^ EFFECT: completely eliminated instability of projectile flight and enhanced range and close grouping of fire. ^ 3 dwg
