Explosive packages are used in military exercises to symbolize ground explosions of artillery shells and hand grenades. In addition, explosive packages can be widely used during various tactical, tactical and special exercises and fire and engineering training.
Explosion packages, purpose, general arrangement, principle of operation, explosive packages of cubic and cylindrical shape.
The cubic-shaped explosion packs are a cardboard box, into the opening of which a fire-resistant cord with a length of 90 mm is inserted into the glue. 40 g of the powder mixture is poured into the box, consisting of 50% fine-grained powder and 50% powder pulp. Outside, a cardboard box is wrapped in two or three layers with twine or braid on all sides..
The outer part of the fire-resistant cord is wrapped with tissue paper, and the very end of the cord is pre-coated with a powder grease to ensure reliable ignition.
The main tactical and technical characteristics of explosive packages of cubic and cylindrical shape.
Cylinder-shaped explosion packages, general arrangement.
The cylindrical-shaped explosion pack is a puff paper sleeve equipped with smoky gun powder (DRP-4) and closed on both sides with cardboard wads. Wads are fixed in the sleeve by rolling it.
The upper wad has a hole in which it is fixed with glue or with the help of a harsh (linen) thread and mastic (in explosive packages manufactured before 1965) a 90 mm long fire-retardant cord. The outer end of the flame retardant cord has a fuse, which is a powder grease.
The principle of operation and the use of explosive packages of cubic and cylindrical shape.
The action of explosive packages of cubic and cylindrical shape is the same. After ignition of the fire-resistant cord, the fire beam in 7-8 seconds reaches the explosive charge from the smoky gunpowder and ignites it. An explosion occurs, accompanied by a sound effect and the formation of a smoke cloud..
When using explosive packages, certain safety measures and rules should be followed. Do not blow them up near people, animals, equipment or buildings. In addition, as a result of long-term storage, the mixture inside the flame-retardant cord may lose its properties and there is a possibility that the explosion package may explode prematurely.
When storing or carrying explosive packages, they should not be exposed to moisture or direct sunlight. When placed in place, explosive packaging must be kept away from open flames, such as bonfires or gas burners..
