Description

Field of technology

The utility model is used in ammunition technology, in particular in shots with fragmentation mines to 60 mm NATO standard mortars - mainly for COMMANDO M60CMA and similar type of COMMANDO mortars, as well as for all 60 mm mortars.

In special military operations requiring maximum concealment and maneuverability, 60 mm COMMANDO mortars are an extremely suitable weapon for striking the enemy's manpower, located outdoors or in field-type shelters, hidden behind buildings or on the roofs of buildings. Due to its light weight and compact design, the shot with a fragmentation mine can be easily carried, transported by light vehicles.

For these reasons, the subject of the present task is the creation of a specialized shot with a fragmentation mine with increased power, increased firing distance, minimum mass and dimensions.

BACKGROUND OF THE INVENTION

Shots from fragmentation mines with a whole body made of steel or cast iron are known. Characteristic of these constructions is the arbitrary fragmentation of the body into striking elements [1].

Shot blast stabilizer blocks are made of steel or aluminum alloys. The characteristic feature of this construction is that when the shot moves in the barrel of the mortar, the friction affects the durability of the mortar.

The equipment of the shots with fragmentation mines with a whole hull is done by casting or auging. The characteristic of this construction is that no high-energy explosive can be used in the form of presses.

The mass of known shots with fragmentation mines made of steel or cast iron with stabilizer blocks made of steel or aluminum alloys is from 1.25 kg to 2.24 kg and they have a length of 0.255 m to 0.420 t.

Technical essence of the utility model

The task of the utility model is to create a shot with a fragmentation mine to 60 mm COMMANDO mortars with increased power, increased firing distance, minimum mass and dimensions.

The problem was solved by creating a shot with a fragmentation mine, consisting of a fragmentation mine containing a body with a centering thickening, and behind the centering thickness there is an annular channel in which an obturator is placed, with a fuse attached at the front end and a stabilizer at the rear end. block, as the main charge is placed in the tube of the stabilizer block, and an additional charge is placed on the tube of the stabilizer block.

According to the utility model, the housing consists of a steel cup with a wall thickness of 2.4 mm to 6.0 mm, with formed semi-finished striking elements with a mass of 0.25 g to 0.75 g and plastic is sprayed on the steel cup, forming the centering thickening, the annular channel and the thread for connecting the stabilizer block. A high-energy explosive in the form of checkers is placed in the steel cup. The explosive in the form of checkers is pressed by a sleeve made of plastic, which has a thread at the front end to connect the fuse, and at the rear end - a thread for

BG 3943 UI connection to steel cup. The stabilizer block consists of a tube made of aluminum alloy with holes at a distance of 3.0 mm to 9.0 mm from each other and with a hole diameter of 1.8 mm to 6.0 mm. On the pipe are mounted from 4 to 12 pieces of fins made of plastic, with length from L = 12.0 mm to 90.0 mm.

The advantages of the utility model are the following.

The shot with a fragmentation mine to 60 mm COMMANDO mortars consists of a fragmentation mine with a body containing a steel cup on which plastic is injected, forming the centering thickening, the annular channel and the thread for connecting the stabilizer block. The stabilizer block consists of a tube made of aluminum alloy, on which are mounted fins made of plastic. The use of plastic reduces the mass of the shot to 0.950 kg and a length of 0.250 mm.

The increased power of the shot is provided by the steel cup with a wall thickness of 2.4 mm to 6.0 mm, with formed semi-finished striking elements with a mass of 0.25 g to 0.75 g and the high-energy explosive in the form of checkers with weight 0.200 kg.

The firing distance has been increased to 2369 tons.

Examples of implementation of the utility model

Shot with a fragmentation mine / figure 1 /, consisting of a fragmentation mine 1, containing a housing 2 with a centering thickening A, and behind the centering thickening A there is an annular channel B, in which a shutter 3 is placed, with a fuse 4 connected at the front end, and at the rear end of the stabilizer block 5, as in the tube 12 of the stabilizer block 5 is placed a main charge, and on the tube 12 of the stabilizer block 5 is placed an additional charge 7. The housing 2 consists of a steel cup 8 with a wall thickness of 2.4 mm to 6.0 mm, with formed semi-finished striking elements with a mass of 0.25 g to 0.75 g. On the steel cup 8 is injected plastic 9, forming a centering thickening A, an annular channel B and a thread for connecting the stabilizer block 5. In the steel cup 8 is placed a high-energy explosive in the form of checkers 10, pressed by a sleeve 11 made of plastic with a thread for connecting the fuse 4 at the front end of the sleeve and a thread for connecting the steel cup 8 at its rear end.

Application and mode of operation of the utility model

The fragmentation mine shot is used to fire 60 mm COMMANDO mortars to hit the enemy's manpower, located outdoors or in field-type shelters, hidden behind buildings or on the roofs of buildings.

The principle of operation of the shot (Figure 1) is as follows.

Ha the body 2 of the mine 1 has a centering thickening A, which is designed to center the mine 1 in the channel of the body of the mortar. Behind the centering thickening A of the mine 1 there is an annular channel B, in which an obturator 3 is placed to reduce the penetration of gunpowder gases between the walls of the channel of the body of the mortar and the mine 1 when fired.

The stabilization unit 5 provides stability to the mine 1 in flight. It consists of a tube 12 with fins 13. In the tube 12 of the stabilizer unit 5 is placed the main charge 6, which is screwed into the bottom, and outside on the tube 12 are placed additional charges 7. The tube 12 of the stabilizer unit 5 has holes for gunpowder gases which are formed during the combustion of the main charge 6 for the ignition of the additional charges 7.

Upon firing, after stabbing the igniter capsule, the main charge 6 is ignited, whose gunpowder gases after piercing the cup 8 and penetrating through the holes in the tube 12 of the stabilizer unit 5, burn the hulls and ignite the gunpowder of the additional charge 7 and give the required initial velocity. of the mine.

After take-off of the mine 1 from the channel of the mortar, the shock-protective mechanism of the fuse 4 moves to the cocked position.

After hitting a barrier under the action of reaction and inertial forces coils during the flight, the fuse is activated.

The detonation pulse received by the detonator initiates the high-energy explosive in the form of checkers 10 of the mine 1, after which the formed products of the explosion break a steel cup 8 with formed semi-finished striking elements, which breaks into about 500 striking elements (fragments) with mass 0, 5 g. An accompanying high-explosive action follows.
