ROCKET Russian patent published in 2000 - IPC

FIELD: rocketry. SUBSTANCE: the rocket has a nose, aerodynamic stabilizing fin and a rocket engine with a relative elongation of the body exceeding 15 rocket calibers. The engine has the nose and tail pipes, inserted solid-propellant charge in the form of two half-charges, whose outer surface carries blocks, and an ignition device located between the half-charges. The engine body is made of pipes of different thickness, with the thickness of the nose pipe equals to 0.7 to 0.9 of the tail pipe thickness. The half-charges are of the same length with an outside diameter making up 0.7 to 0.9 of the rocket caliber and relative elongation of 7 to 8 rocket calibers. The blocks are installed in the rocket longitudinal axis in succession with removal of them from the ends of the half-charges by 0.2 to 0.3, and between them by 0.06 to 0.13 of the length of the half-charge, and radial displacement relative to each other in the plane of rocket cross-section by 120 deg. The length of each block makes up 0.04 to 0.07 of the length of the half-charge, and the igniting compound of the ignition device is made of black rifle powder with a grain diameter equal to 0.001 to 0.002 of the length of the half-charges. EFFECT: enhanced stability of interior ballistic characteristics of the rocket, enhanced range and close grouping of fire. 4 dwg
