Circular cumulative bombs for side cutting with explosives

Circular cumulative bombs for side cutting with explosives


The cumulative charge is a type of explosive charge where the orientation of the explosive jet depends on the filling form.

Cumulative charges are divided by form, direction of energy, detonation and function.

Cumulative charge are shared with those with on to tapered cumulative charges and line cumulative charges or cutters.

The conical charge  are intended for puncturing the targets. For conical charges, the cumulative space is a conical shape, and the detonation energy is directed to the point. The ability to act et  the conical cumulative charge is defined by the depth of perforation in the material.

Line cumulative cutters are intended for cutting. Their lining is longitudinally long and the detonation energy is directed towards the direction. The ability of the line cumulative charge action is measured with the maximum thickness of the material that the cutter can cut.

The conical charges were developed for military purposes, for the punching of armor of tanks and other armored vehicles.

Line cumulative cutters developed from conical cumulative perforators. Most used for civilian purposes. They have been developing since 1950. Detonating the explosive charge leads to the direction of the detonation energy towards the cumulative space, the impact wave hits the lining  deforms and accelerates. Lining is a source of heavy molecules that increase the kinetic energy of the process.

Cutting efficiency depends on the weight of the lining and mass of the explosive charge. Explosion is directed into a straight line by the  explosive. The jet pressure on the material is considerably higher than the compressive strength of the material.  The jet penetrates into the material and forms a cut in the material. The target material deforms. When the kinetic energy of the jet is lowered in the penetration process, further penetration is stopped. Due to pressure waves, cracks in the target material are created after the penetration action. The sum of the action of these forces gives the total thickness of the material that the line cumulative cutter can slit.

Line cumulative cutters are used in various industries. They are used as part of certain technologies for cutting metals and other materials. The use of line cumulative cutters is most common in mining, petroleum mining, construction, space industry, fire brigade. It is also used for demining and for military purposes.

It is also possible to create a third type of cumulative jet, and it is a circular cumulative jet.

Such a circular cumulative jet would trigger an explosive charge in a bomb with a side empty space spreading from the center of the bomb to the lateral edges. Such an explosion would cause cuts to all the obstacles surrounding the bomb. Such an explosion could cause the cutting of trees, tall grass, walls and pillars in much larger space than ordinary explosions.

An plane bomb of 100 kg that would explode on top of trees could cut tree branches up to 50 meters in diameter. Explosions at ground level  could collapse trees up to 20-30 meters in diameter.

Small mortar grenades with circular cumulative filling could be used to clean the area from the bushes in front of combat positions. This would facilitate the defense of sudden attacks.
