Penetration equation for shaped charge warhead
Ashley from Fairfield Age: 30. Men who are just dreaming to try something unusual, I will help to make all dreams come true.
Liners have been made from many materials, including various metals [43] and glass. The most common shape of the liner is conical , with an internal apex angle of 40 to 90 degrees. Non-homogeneous distribution of the inclusions can also be achieved. The fuels used in these devices, along with the secondary combustion reactions and long blast impulse, produce similar conditions to those encountered in fuel-air and thermobaric explosives.

Review Of Works On Shaped Charges
The jet tip velocity depends on bulk sound velocity in the liner material, the time to particulation is dependent on the ductility of the material. If the nose probe strikes one of the cage armor slats, the warhead will function as normal. Casey. Hummer, Charles At typical velocities, the penetration process generates such enormous pressures that it may be considered hydrodynamic . to a good approximation, the jet and armor may be treated as inviscid , compressible fluids see, for example, [36] , with their material strengths ignored. The BAE is mainly caused by the high-temperature and high-velocity armor and slug fragments being injected into the interior space and the blast overpressure caused by this debris.

Introduction to shaped charges
This page was last edited on 3 January , at The dispersion of the second phase can be achieved also with castable alloys e. One of the earliest uses of shaped charges was by German glider-borne troops against the Belgian Fort Eben-Emael in 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 [31] [32] [33] and for boring holes.
