SEPARATION SYSTEM Russian patent published in 2000 - IPC

FIELD: space rocket engineering, applicable for attachment of the space vehicle to the rocket and separation from it after injection. SUBSTANCE: system has band joints, each provided with a relaxant, coupling bolt, coupling and two cylindrical bushes, strain gauge and a charge-driven lock. The charge-driven lock is made in the form a link-clamping mechanism engageable with the tapered head of the coupling bolt. The relaxant has a catch, explosive pin and a body with ducts and cavities, one of which accommodating a piston with a piston rod. The catch is made in the form clamps in the axis of rotation for simultaneous engagement with the piston rod and explosive pin. The other body cavities accommodate the hydraulic system. The relaxant body is made for movement in the axis of its symmetry, and the coupling bolt is connected to the piston rod. The coupling bush is engageable with its one end with the relaxant, and with the other - with the cylindrical bush. At separation the system provides for loosening of the tension of the coupling band up to the minimum required for holding of the space vehicle on the rocket stage. EFFECT: considerably reduced impact loads at separation. 2 cl, 9 dwg
