What is meant by shaped charge?
Definition of shaped charge : an explosive charge the energy of which is focused in one direction so that it usually achieves an armor-penetrating effect.
What are shaped charges used for?
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.
How do shaped charges 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. A detonator is activated to initiate the explosive material to generate a detonation wave. This wave collapses the liner and a high velocity metallic jet is formed.
What is shaped charge explosives?
The shaped charge was an explosive formed into a hollow cone and lined with heavy metal; upon detonation, the explosive gases and molten metal formed a high-velocity jet capable of punching through armour.
What is a linear shaped charge?
Linear Shaped Charge (LSC) is used to cut various types of metal in separation systems, from launch vehicles to missiles, in space, military and underwater applications. Linear Shaped Charge is a continuous explosive core enclosed in a seamless metal sheath, formed into an appropriate shape to sever the target.
What is hollow charge effect?
Definition of hollow charge : an explosive which concentrates its force in one direction (as in a projectile designed to blow a hole through armor plate)
How do Hesh rounds work?
HESH rounds are thin metal shells filled with plastic explosive and a delayed-action base fuze. The base fuze detonates the explosive milliseconds later, creating a shock wave that, owing to its large surface area and direct contact with the target, is transmitted through the material.
What is a shaped charge warhead?
Abstract: A shaped charge warhead comprises a fragmenting wall defining a space which contains a shaped charge liner that is conical in shape having a large diameter base.
What is in det cord?
cord, detcord, primer cord or sun cord) is a thin, flexible plastic tube usually filled with pentaerythritol tetranitrate (PETN, pentrite). With the PETN exploding at a rate of approximately 6400 m/s, any common length of detonation cord appears to explode instantaneously.
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.
Is HESH better than heat?
Unlike high-explosive anti-tank (HEAT) rounds, which are shaped-charge ammunition, HESH shells are not specifically designed to perforate the armour of main battle tanks. While only effective against tanks without spaced armour or spall liners, the round is still highly favoured for combat demolition purposes.
How effective is HESH?
The major advantage of HESH lies in its usefulness as a multipurpose round. It is approximately 90% as effective as a conventional High Explosive (HE) round against unarmoured targets and considerably better than HE against bunkers and buildings.
Which is the best definition of a shaped charge?
Freebase(0.00 / 0 votes)Rate this definition: Shaped charge. A shaped charge is an explosive charge shaped to focus the effect of the explosive’s energy.
How are shaped charges used in everyday life?
In non-military applications shaped charges are used in explosive demolition of buildings and structures, in particular for cutting through metal piles, columns and beams and for boring holes. In steelmaking, small shaped charges are often used to pierce taps that have become plugged with slag.
How are shaped charges used in the military?
Modern military. 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.
How big can a shaped charge penetrate steel?
A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD), though greater depths of 10 CD and above have been achieved.
