ASSEMBLY JIG FOR STOPPER OF SOLID ROCKET MOTOR AND ASSEMBLY APPARATUS FOR STOPPER OF SOLID ROCKET MOTOR USING THE SAME AND ASSEMBLY METHOD FOR STOPPER OF SOLID ROCKET MOTOR USING THE SAME

摘要

The present invention relates to a fixture for assembling a plug for a solid propulsion engine, a plug assembly device for a solid propulsion engine using the same, and a method for assembling a plug for a solid propulsion engine using the same. The rear plug is rotated while the propellant fixing plate member is pushed away from the rear plug. The internal position of the propellant grain and solid propulsion engine accessories are changed by screwing it into the combustion pipe, or damage such as scratches or ruptures are prevented in some parts, greatly reducing the defect rate during assembly, and friction with the propellant grain during assembly. Does not occur, thereby preventing the occurrence of safety accidents during assembly, and greatly improving the safety of assembly work.
