Description

The utility model relates to the field of weapons and military equipment, in particular to the design of explosive devices, and can be used on unmanned aerial vehicles.

A miniature unmanned attack aerial vehicle-kamikaze T-RAM is known (Karpenko A.V. Miniature unmanned aerial vehicle TEXTRON T-RAM MAVERICK (USA) MINIATURE UNMANNED AERIAL VEHICLE TEXTRON T-RAM MAVERICK (USA) / Military-technical collection "Bastion" / [Electronic resource]. - Access mode: http://bastion-karpenko.ru/maverick/ - (date of access: 09/19/2024)). The T-RAM device is a combination of a miniature unmanned aerial vehicle (UAV) with a warhead of a 40-mm grenade of an anti-personnel grenade launcher installed on it. The effectiveness of the fragmentation action of such ammunition, both against dispersed manpower and against moving vehicles, largely depends on its orientation at the moment of detonation and is maximum when it is in a vertical position. Putting the UAV into a vertical dive and, at the same time, ensuring its orientation in the direction of a moving target, as well as the activation of the ammunition in the immediate vicinity of the target using the control station is an extremely difficult task for the operator, and sometimes practically impossible, since for complete coordination of the destruction zone of the fragmentation warhead and the entire surface of the moving target, the required complexity of the UAV flight trajectory increases so much that in some cases it goes beyond the capabilities of the control station operator, which negatively affects the effectiveness of the fragmentation action of the warhead of the strike complex on the target.

An unmanned strike system (RU 2558528) is known, which contains a ground control station for an unmanned aerial vehicle (UAV), a rangefinder-target designator, a UAV with a satellite navigation system, a video camera, a directional fragmentation munition with a fragmentation block in the form of two opening panels with a fragmentation jacket, an explosive substance, an electric detonator, an explosive pyroelement with a pyro-pusher, an additional kinematic connection in the form of a rigid rod and a two-link mechanism, a lever. The panels are the form-forming parts of the UAV fuselage with a detonation circuit switch.

The disadvantages of this device include the complexity of the design, high cost, and the inability to use different types of warheads.

There are known designs of disposable unmanned aerial vehicles adapted for use with various warheads, often with a shot from an RPG-7 (FPV kamikaze drones [Electronic resource]. URL: https://dzen.ru/a/ZW3GpgvvrSFcMOG8 (Access date 08/19/2024)). Also known are homemade ammunition in the form of a tube with explosives, the striking elements are located either inside the tube or outside.

The disadvantages of such devices include the unreliability of the design and the amateurish nature of their production.

A unified modernized fuse for a hand grenade, the UZRGM, is known. It is designed to detonate the explosive charge in the F-1, RGD-5, and RG-42 grenades. The fuse consists of a firing mechanism and a fuse. In service use, the striker is constantly cocked and held by the trigger fork. The trigger is connected to the striker tube by a safety pin, which is pulled out before throwing. When the grenade is thrown, the trigger is separated and releases the striker, which, under the action of the mainspring, pricks the primer cap, igniting it. The detonator cap initiates the detonation of the explosive charge, which shatters the grenade body into fragments.

The disadvantages of using this fuse include the impossibility of using it for ammunition dropped from an unmanned aerial vehicle.

The purpose of the utility model is to expand the possibility of using a unified fuse for a hand grenade of the modernized UZRGM for ammunition dropped from an unmanned aerial vehicle.

The technical result is the development of a design that ensures the retention of the trigger lever of the unified fuse of the hand grenade of the modernized UZRGM after the safety pin is pulled out, for use with ammunition dropped from an unmanned aerial vehicle.

This is achieved by the fact that in the device of destructive action, dropped from an unmanned aerial vehicle, containing a unified fuse of a hand grenade modernized UZRGM, a safety pin, a trigger lever and a casing of the ammunition, a safety ring made with four tabs is installed on the unified fuse of a hand grenade modernized UZRGM with a trigger lever, and in front of each tab of the safety ring there is a groove that reduces the thickness of the safety ring, the length of each tab of the safety ring is not less than the diameter of the casing of the ammunition.

The utility model is explained by diagrams, where Fig. 1 shows a destructive device dropped from an unmanned aerial vehicle (front view); Fig. 2 is a section A-A; Fig. 3 is a model of a unified fuse for a hand grenade of the modernized UZRGM with a safety ring; Fig. 4 is a destructive device dropped from an unmanned aerial vehicle with an installed safety ring.

The device consists of a unified fuse of a hand grenade modernized UZRGM 1, a safety pin 2, a trigger lever 3 installed on a unified fuse of a hand grenade modernized UZRGM 1 with a trigger lever 3, a safety ring 4 made with four tabs, and a body of ammunition 5. The safety ring 4 holds the trigger when pulling out the safety pin 2. In front of each tab of the safety ring 4 there is a groove that reduces the thickness of the safety ring 4 and is the initiator of the place where the rupture of the safety ring 4 will occur, which releases the trigger lever 3.

The safety ring 4 with four tabs is made of a fragile material, such as plastic. The length of each of the four tabs of the safety ring 4 must be no less than the diameter of the ammunition body 5 so that the tabs rest against the surface (obstacle) when falling, and the safety ring 4 is destroyed along the grooves located in front of each tab. The grooves reduce the thickness of the safety ring 4, being the initiator of the place where the rupture of the safety ring 4 will occur. After the destruction of the safety ring 4, the trigger lever 3 is released, the unified fuse of the hand grenade of the modernized UZRGM 1 is initiated, and the explosion of the ammunition occurs.

The device operates as follows. A unified fuse of a hand grenade modernized UZRGM 1 with a trigger lever 3 is attached to the body of the ammunition 5, onto which a safety ring 4 made with four tabs is installed. The device is secured to the unmanned aerial vehicle, the safety pin 2 is pulled out, after which, on command from the operator, the unmanned aerial vehicle takes off. When the unmanned aerial vehicle is above the target, the device is dropped on command from the operator. When it encounters an obstacle or surface, the device falls on its side, when any tab of the safety ring 4 hits the obstacle or surface, the safety ring 4 is destroyed along the grooves in front of the tabs, releasing the trigger lever 3, the unified fuse of the hand grenade modernized UZRGM 1 is initiated, and the ammunition explodes.
