Description

Grenade detonation device for attack drone The present invention relates to a grenade detonator, and more specifically, to a grenade detonator for a drone that is mounted on a drone in a battlefield, transported toward a target point, and then detonated. Recently, there has been an increasing demand for weapon systems capable of striking enemy targets from a distance, and technology for remotely transporting and dropping explosives using drones is receiving particular attention. Hand grenades have traditionally been operated by being thrown directly by personnel. However, this direct throwing method had limitations in range, restricting safety and operational flexibility in that the operator had to approach within a specified distance of the target. Accordingly, methods for remotely dropping grenades using drones have been studied from various angles. However, since grenades are structurally small and spherical, if they are not properly secured, there is a risk that they may roll away from the transport mechanism or have their safety release, causing them to explode at an unexpected location. In addition, since multiple safety devices controlling the detonation of the grenade, such as safety clips, safety pins, and safety handles, are designed based on manual operation by the operator, there were difficulties in controlling detonation in a remote environment using existing transport methods. Accordingly, there was a need to develop a new type of grenade-specific detonator capable of safely transporting grenades using a drone while simultaneously releasing safety devices sequentially to induce stable detonation at the target location.
