[0001] The present invention relates to a lining and a weighing system for loading solid explosives (propellant material) into a guided weapon propulsion system, and more specifically, to a lining and a weighing system for loading solid explosives (propellant material) into a motor, which is a guided weapon propulsion system, by applying a liner to protect the internal structure of the motor and improve the adhesion of the solid explosives before loading the solid explosives into the motor. Background Technology

[0003] Generally, projectile propulsion systems are a type of rocket engine used in everything from space launch vehicles to guided weapons such as missiles, and can be broadly divided into liquid and solid propulsion systems.

[0005] Among them, solid propellant engines generate thrust by burning solid fuel in the form of a mixture of fuel and oxidizer.

[0007] Solid propellant engines are characterized by a simple structure, ease of handling, excellent reliability and storability, and are cost-effective and have a large thrust capability, so they are mainly used in guided weapons such as missiles, and technologies such as U.S. Patent Publication No. 2019 / 0120174 "precursor compositions for an insulation, insulated rocket motors, and related methods" are continuously being developed.

[0009] These solid propellant engines (hereinafter referred to as motors) proceed sequentially through processes such as the lining process, which involves coating the inside of the motor to fill it with solid explosives (propellant material or solid fuel), the filling process, the core insertion process, the curing process, and the core removal process, and at each process, a worker directly moves and fixes each motor.

[0011] Accordingly, as the risk of explosion from solid explosives is high and workers are exposed to the risk of safety accidents for extended periods, there is a growing need for the development of technology to automate this process.

[0013] In addition, the lining process involves applying a liner by having a worker manually coat the inside of the motor using spraying or brushing; however, there were problems such as significant variations in coating quality depending on the worker's skill level and difficulty in manufacturing with a uniform thickness.

[0021] In addition, the weight measuring unit is characterized by comprising a measuring plate on which a sensor for weight measurement is placed, and a lift that lifts the measuring plate so that the measuring plate can lift each motor holder from below to a predetermined height to measure the weight.

[0022] In addition, the motor holder is characterized by comprising a lower plate on which a motor is mounted, an upper plate spaced apart from the lower plate by a predetermined distance and having an outlet formed in one direction, a plurality of support members disposed between the lower plate and the upper plate, a support plate disposed in the other direction between the lower plate and the upper plate to fix the side of the motor, and a central block protruding from the lower surface of the lower plate and inserted into the mounting hole of the fixing plate.

[0023] In addition, the central block is characterized by having a flat bottom surface formed so that the weight measuring unit can lift the motor and motor holder to a predetermined height at the bottom of the fixed plate to measure the weight. Effects of the invention
