ROCKET PROJECTILE LAUNCHED FROM LAUNCHING TUBE Russian patent published in 1998 - IPC

Abstract RU 2115882 C1

FIELD: rocket projectiles launched from launching tubes, applicable in salvo launching systems. SUBSTANCE: rocket projectile has a nose cone with mounting seat for projectile has a nose cone with mounting seat for braking rings, fuze, engine with contact cover, tailplane with obliquely installed blades, brake rings and guide pin. Each of tailplane opening blades is bent in a helix. The blade generating line is positioned relative to its longitudinal axis at an angle deg. The blade leading edge on the outer side has a bevel with length l_c= (0,04-0,1)d, made at angle α_c= (10-16)α₀. The guide pin is installed on the engine body in the plane passing through the axis of attachment of one of the tailplane blades and projectile longitudinal axis at a distance of (1.8-2.0)d from the nozzle exit section. Mounting seat for braking rings is located from the fuze nose at a distance of (1.2-1.5)d. The outside diameter of the smaller braking rings is (0.7-0.8)d, and that of the larger braking rings is (0.9-0.95)d, where ω-engine solid propellant, and h, q_n, d, α_c9610 - projectile length, passive mass, caliber and blade leaching edge bevel angle, respectively. EFFECT: enhanced firing range. 3 dwg
