0

Since 2015, Z121 Factory has implemented and completed 85 science and technology projects, including perfecting the K51SK fire particle production technology.
According to the People’s Army, in the period of 2020 up to now, Z121 Factory has implemented dozens of scientific and technological projects at all levels, projects and programs to rationalize production; 32 mechanization and automation projects and 1,429 technical innovation initiatives.

The factory also cooperates with research institutes to successfully test many products with complex technical requirements to meet the requirements of military modernization. Vietnam-made anti-tank ammunition. Prominent in the plant’s science and technology work is focusing on implementing topics to completely solve complex technical problems and problems that have lasted for many years. Many high-value initiatives put into effective application such as: Researching and perfecting K51SK fire particle production technology; research on drying wet fire seeds by infrared drying method; perfecting the production technology of spark tube explosion to improve product quality, overcome the phenomenon of electric spark tube resistance decline, stabilize quality, and reduce product failure rate; research to improve the quality of bullets PG9, OG9, B41M… It is known that OG-9 is a fragmentation explosive used to destroy enemy troops and vitality, destroy enemy fire stations at a range of up to 1000m and destroy enemy clusters at a distance of up to 4500m. . The OG-9 explosive grenade launcher has a shell made of ductile iron inside with a 735g TNT-type explosive and a ballistic stabilizer: The propellant tube is drilled with a row of air vents at right angles to each other and has eight raised fixed wing edges, oblique cuts on the wings for the projectile to rotate around its axis while in the air; The tail of the launch tube has a connecting rod for the dose and line marking. The OG-9 Detonator includes: Cone-shaped detonator housing with detonator; Long range detonator, detonation and cross detonation. The inertial mechanical element is used to activate the warhead ready for combat at a distance of 2.5 – 18m from the cross-section of the barrel and has: Detonator housing with dedicated cutouts, cartridge springs, locking balls and 4 safety locking balls. The grooves on the wall of the fuse housing are zigzag, through and straight. The flaming element is used for the pyrotechnics to strike the detonator’s fire particle when it collides with an obstacle and has an immediate, inertial effect. The pyrotechnic unit includes a flamingo cap, a gravity ball with horizontal locking pins and grooves, a flintlock, a pyrex housing and a conical spring. The inertial part includes: gasket, detonator tube and protective gasket. Cross-piercing detonator is a part used to detonate bullets when encountering an obstacle with a diagonal angle of impact greater than 8 degrees, a part consisting of a conical guide tube connected to a detonator tube, a directional ring. cone and decoys. In order for the inertial silver to not move, the ring is held in place by a compression spring and the edge of the tube containing the needle. The fact that Vietnam is self-sufficient in the production of OG-9 ammunition is especially important in the combat training and combat readiness of the army, which is not dependent on external supplies.
