Russian engineers have developed and patented a cumulative warhead for attack FPV drones, which received a universal unit for installing various fuzes and initiation means. The developer was JSC "Scientific and Production Association "Bazalt"".
The new design is intended to expand the possibilities of using close-combat cumulative warheads as part of unmanned aerial vehicles. The main difference of the development lies in replacing the standard detonation unit with a universal system that allows the use of several variants of fuzing devices.
According to the patent, the warhead is made on the basis of a cumulative charge with copper lining and a screen, placed inside a body with a fairing. A special mounting unit is installed in the bottom part, consisting of an explosive pellet, a sleeve with a connecting thread, and a transport element with a screw.
This scheme allows the use of different types of initiation means depending on the tasks and configuration. The design is intended for both mechanical fuzes and electric detonators.
The engineers abandoned a number of elements necessary for the operation of the standard grenade launcher version of the ammunition, including a piezoelectric generator, a current-conducting cone, and an insulating ring. This made it possible to simplify the warhead device and adapt it for use on unmanned carriers.
The development solves a problem that previously arose when using cumulative warheads of grenade launcher rounds on FPV drones. Such warheads required additional refinement before installation on unmanned platforms, since the standard triggering mechanisms were designed for launch conditions from a grenade launcher.
The new universal unit makes the warhead more flexible in application: the operator or manufacturer can choose the necessary initiation option without changing the main design of the product.
The description of the development notes that a similar unit is already used in a number of warheads for close-combat weapons, including products from the PG-26, PG-7L, PG-7R, and TBG-7 families.
The patented design allows for the creation of more versatile cumulative warheads for attack FPV drones, increasing compatibility with various initiation systems and simplifying their adaptation to modern unmanned platforms.
