How does a explosively formed penetrator work?

How does a explosively formed penetrator work?

EFPs are self-forging warheads designed to effectively penetrate armor and fire in a way similar to cannons. When fired, the explosive charge deforms a concave metal plate into a slug or rod shape. The shape forms as the plate accelerates toward an intended target. EFPs can breach tank armor 300 feet away.

How fast does an EFP travel?

The end result is that a shaped charge produces a very narrow jet of metal at extreme speed – several thousand meters per second – whereas an EFP produces a single slug moving at much slower speed (but still over a thousand metres per second).

What is shaped charge explosive device?

A shaped charge is an explosive charge shaped to focus the effect of the explosive’s energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry.

What is explosively formed projectile?

An explosively formed penetrator (EFP), also known as an explosively formed projectile, a self-forging warhead, or a self-forging fragment, is a special type of shaped charge designed to penetrate armor effectively.

How is dynamite produced?

Dynamite is formed into explosive sticks that feature a wick and a blasting cap. The wick is lit, which leads to a small explosion when it reaches the blasting cap. When the blasting cap explodes, the nitroglycerin then causes a much larger explosion. You may see some explosives labeled “TNT” that look like dynamite.

What is Munroe effect?

Definition of Munroe effect : the greatly increased penetration of an explosive into a surface (as of metal or concrete) that is caused by shaping a conical or hemispherical hollow in the forward end of an explosive cartridge.

Is copper used in explosives?

Compounds such as copper acetylide have explosive properties, even though metallic copper does not. Copper tetrammine is another compound with the potential for explosion. In addition, metallic copper causes the explosive decomposition of hydrogen peroxide when the solution has a concentration of 30 percent or greater.

What are explosives made of?

Chemical composition A chemical explosive may consist of either a chemically pure compound, such as nitroglycerin, or a mixture of a fuel and an oxidizer, such as black powder or grain dust and air.

What is an Explosively Formed Penetrator?

USAF Research Laboratory. An explosively formed penetrator (EFP), also known as an explosively formed projectile, a self-forging warhead, or a self-forging fragment, is a special type of shaped charge designed to penetrate armor effectively.

What is the effect of the explosive charge?

As the name suggests, the effect of the explosive charge is to deform a metal plate into a slug or rod shape and accelerate it toward a target. They were first developed as oil well perforators by American oil companies in the 1930s, and were deployed as weapons in World War II.

What will happen when a copper bomb hits an asteroid?

The explosion will form a copper explosively formed penetrator hitting the asteroid with a velocity of 2 km/s. The crater created by the impact will be a target for further observations by the onboard instruments. The shaped charge will consist of 4.5 kg of plasticized HMX and a 2.5 kg copper liner.

What are the ejectefps used for?

EFPs have been used in improvised explosive devices against armoured cars, for example in the 1989 assassination of the German banker Alfred Herrhausen (attributed to the Red Army Faction), and by Hezbollah in the 1990s.
