Extended charge

An elongated charge is an elongated explosive (explosive) charge (the ratio of length to cross section is 5: 1 or more).

An elongated ring charge used to divide the rocket stages ( pyroshangout ). The figure shows: 1-first stage; 2-second stage; 3- BB ; 4- outer ring closing BB; 5 - undermined (cut) power element .

Depending on the purpose, extended charges can be:

cumulative
high explosive

Content

Cumulative extended charges

They are used for interrupting (cutting) metal structures.

Ring shaped charges (pyro-frames)

In rocket science , ring-shaped cumulative charges ( pyro-frames ), used to divide rocket stages, are widespread. The use of pyro-frames in the design significantly improves the mass-dimensional characteristics of the rocket.

High explosive charges

They are used for the destruction of metal, reinforced concrete, wooden structures, undermining the soil and making passages in minefields using an explosive method (mine clearance charges).

Elongated clearance charges have a mass of explosives from hundreds of grams (for making pathways in anti-personnel minefields) to several kilograms per linear meter of length (for making passages in anti-tank minefields). Charges, depending on the type, are fed into the minefields by a tank , powder propellant rocket engines or manually.
