METHOD FOR SEPARATING ROCKET SECTIONS Russian patent published in 2021 - IPC B64G1/64 F42B15/36 

FIELD: aviation.

SUBSTANCE: invention relates to methods for dropping or separating objects, primarily rocket stages, sections and payloads from the load-bearing structures of an aircraft, on any sections of the flight trajectory, and can be used in the field of aviation and rocket technology. The method for separating rocket compartments includes manufacture of power attachment units of the frames of the separated sections, explosive release units for the power attachment units and the section pusher. A movable flange is therein installed in the frame of one of the separated sections on guides fixed in the frame through windows made in the movable flange, providing a possibility to move the movable flange along the guides in a direction perpendicular to the mating plane of the frames. The frames are pressed along the mating surfaces by tightening the tightening bolt, abutting the head of the tightening bolt on the frame. An annular groove with a conical side wall is therein made in the body of the bolt, placing the wall on the side opposite to the direction of tightening of the bolt. The abutting part of the head of the tightening bolt is made in the form of separate spacer plates partially submerged in the groove of the body of the tightening bolt, with the shape of the submerged part identical to the shape of the groove of the body of the tightening bolt, and placed in a cylindrical cut made in the movable flange. The explosive release unit for the power attachment units itself is installed in the movable flange and made in the form of a pneumatic cylinder with a piston configured to shift relative to the movable flange and the frame, made whereon is a protrusion serving as a section pusher and passing through the cut made in the frame, abutting on the frame of the other of the separated sections.

EFFECT: provides a possibility to reduce the aerodynamic resistance of the structure during flight in the atmosphere and ensure performance capability in a large temperature range.
