23 results about "Gunpowder" patented technology

Gunpowder, also known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur (S), charcoal (C), and potassium nitrate (saltpeter, KNO₃). The sulfur and charcoal act as fuels while the saltpeter is an oxidizer. Because of its incendiary properties and the amount of heat and gas volume that it generates, gunpowder has been widely used as a propellant in firearms, artillery, rockets, and fireworks, and as a blasting powder in quarrying, mining, and road building.

Method for increasing effective range, destructive force and accuracy by having counterweight jacket for moving center of gravity of bullet (SHELL) forward

PCT designated stageWO2026106244A1Ammunition projectilesProjectilesTrajectory of a projectileRifling
The present invention relates to a method for improving flight stability, effective range, accuracy, and destructive force by moving the center of gravity of a bullet (shell) forward, and the bullet (shell). To this end, the front part of a counterweight jacket of the bullet (shell) is designed to be thicker or higher in density than the rear part thereof, so that the center of gravity is naturally moved forward. This structural feature stabilizes the trajectory by minimizing the yaw angle during flight, and increases the force of impact transmission to the target. In addition, a material having a low specific gravity is used inside a gunpowder contact part and the rear part to further strengthen the effect of moving the center of gravity to the front part. The present invention can maintain a stable flight trajectory in both ground and underwater environments, and maximizes the performance of a bullet (shell) to increase an effective range, destructive force, and accuracy.
