How powerful is a shaped charge?
The speed can reach 10 km/s, peaking some 40 microseconds after detonation; the cone tip is subjected to acceleration of about 25 million g. The jet tail reaches about 2–5 km/s. The pressure between the jet tip and the target can reach one terapascal.
What is the 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.
What are shaped charges used for?
Shaped charges are devices in which an explosive load is used to collapse a (usually metal) liner, thereby creating a high velocity jet that is capable of penetrating deep into metal, concrete or other target materials (Walters & Zukas, 1989).
How does a shaped charge warhead work?
A shaped charge is a concave metal hemisphere or cone (known as a liner) backed by a high explosive, all in a steel or aluminum casing. When the high explosive is detonated, the metal liner is compressed and squeezed forward, forming a jet whose tip may travel as fast as 10 kilometers per second.
Is RPG shaped charge?
The RPG warhead being used against tanks and other armor often has a shaped charge explosive warhead. A shaped charge is an explosive charge shaped to focus the effect of the explosive’s energy.
Are torpedoes shaped charges?
Nuclear torpedoes have also been developed, e.g. the Mark 45 torpedo. In lightweight antisubmarine torpedoes designed to penetrate submarine hulls, a shaped charge can be used. Detonation can be triggered by direct contact with the target or by a proximity fuze incorporating sonar and/or magnetic sensors.
What are shaped charges made of?
military explosives A shaped charge normally consists of a cone made of metal or glass surrounded by a high-strength, high-density explosive and means to obtain the proper standoff,…
How do linear shaped charges work?
How do shaped charges work? In Linear Shaped Charges, the LSC or FLSC explosive material generates a detonation high pressure wave traveling through its length. The focusing of the high-pressure wave collapses the metal sheath forming a high velocity metallic jet.
How does heat warhead work?
The warhead functions by having an explosive charge collapse a metal liner inside the warhead into a high-velocity superplastic jet; this is capable of penetrating armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD).
What is a warheads explosive charge called?
Types of warheads include: Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave….Detonators.

What is a a shaped charge?
A shaped charge is an explosive charge shaped to focus the effect of the explosive’s energy. Various types are used to cut and form metal, initiate nuclear weapons, penetrate armor, and perforate wells in the oil and gas industry.
What happens when a shaped charge is detonated?
These shaped charges, when detonated, produce a high-pressure, high-velocity jet, the direction of the jet being dictated by the orientation of the shaped charge inside a carrier.
What is a shaped charge warhead?
The common term in military terminology for shaped charge warheads is high explosive anti-tank (HEAT). HEAT warheads are frequently used in anti-tank guided missiles, unguided rockets, gun-fired projectiles (both spun and unspun), rifle grenades, land mines, bomblets, torpedoes, and various other weapons.
What is the shape of the explosive charge in a bomb?
The explosive charge is often contained in a plastic tube whose upper part looks like a cylinder and whose lower part ends at a cone of metallic liner. The liner material may be steel, aluminum, copper, and other metallic materials. Figure 25.3. Diagram of shaped charge and its principle.
