Controlled Fragmentation Warhead for UAVApplications
Abstract
This paper presents theoretical assessment of controlled fragmentation (CF) warhead and its application for (Unmanned Aerial Vehicle) UAV. It is a great challenge to the designer to make small warheads with precision for defeat ofground targets. Attempts have been made to optimize the performance parameters of small warheads to be used in UAVs for defeat of specified ground targets. Warhead performance parameters are characterized by mass distribution and special distribution, velocity of fragments and penetration performance of fragmets against ground targets. Lethality of warhead depends on explosive filling, case materials and controlled fragmentation techniques. Parametric studies are carried out to improve the performance parameters in the best possible manner. The theoretical model shows that the warheads in the weight class of 1kg can defeat simulated targets of 5-mm thick mild steel at a lethal radius of 10m, generating more than 250 numbers of 1 to 2-g compact fragments in beam angles of the range of 100-120.To check out the efficacy and effectiveness, two cylindrical warhead prototypes using controlled fragmentation were fabricated and tested in similar conditions.
