JET PROJECTILE Russian patent published in 1998 - IPC

FIELD: rocketry. SUBSTANCE: jet projectile has a sustainer stage with the mated engine, mating device in the form of a taper fairing with the central tube, and a staging mechanism. The fairing has a thin wall, the central tube inside diameter equals the sustainer stage outside diameter. The fairing is connected to the engine through a threaded adapter ring and installed on the sustainer stage up to the stop against the shoulder of the annular segments of the annular groove made in the sustainer stage, and is tightened by a slit nut. Installed between the fairing tube and slit nut is the staging mechanism in the form of a ring frame-diaphragm with radial ribs, whose external side carries a split spring ring with a trapezoid groove on the outside engaged with the mating end surfaces of the fairing and threaded adapter ring of the engine, and a threaded distance sleeve with a chamfer on the end face is installed inside it. Positioned in the diaphragm ribs are chamfered cylindrical pins, with their one end resting on the inner surface of the split spring ring, and the other end being engaged with the chamfer of the threaded distance sleeve installed on the mating spring slit nut with a shoulder freely fitted on the aft part of the sustainer stage, with its end resting on the front end of the fairing tube, and the nut shoulder - on the frame-diaphragm. A piston actuator with a delayed-action electric igniter is installed inside the fairing. The slit nut installed on the aft part of the sustainer stage has an external annular groove and is embraced by a clamp with T-shaped lugs at the joint. The tie linked with the actuator piston is made as a lock embracing the clamp lugs and secured by a shear pin, and the fairing on the inner side is connected to the radial ribs of the staging mechanism by spring tensioners in protective shells. EFFECT: improved design. 4 dwg
