For example, the detonation of an average 105 mm shell produces several thousand high-velocity (1,000 to 1,500 m/s) fragments, a lethal (at very close range) blast overpressure and, if a surface or sub-surface burst, a useful cratering and anti-materiel effect – all in a munition much less complex than the later versions of the shrapnel shell.
One easy comparison between fragmenting HE and shrapnel shells would be to imagine a shell of each type standing stationary and base-first on the ground; a high-explosive shell would be equally lethal if detonated in this state vs. detonating on impact after being fired, whereas a shrapnel shell would ineffectually fire its contents only a few ...
Entered service in 1970. Uses the 3V-21 detonator (mass = 0.431 kg, reliability = 0.98). The projectile creates between 600 and 2,000 fragments. The body is made up of 45Kh1 steel or 60S2 high-fragmentation steel for modern projectiles. Modern projectiles creates up to 2,500 effective fragments. Country of origin: Soviet Union; Round weight: 33 ...
The shrapnel shell was invented by Henry Shrapnel of the British Army in about 1780 to increase the effectiveness of canister shot. It was used in the later Napoleonic wars and stayed in use until superseded in Artillery of World War I. Modern shells, though sometimes called "shrapnel shells", actually produce fragments and splinters, not ...
Typical World War I shrapnel round: 1 shell bursting charge 2 bullets 3 nose fuze 4 central ignition tube 5 resin matrix 6 thin steel shell wall 7 cartridge case 8 propellant. Shrapnel shells are an anti-personnel munition which delivered large numbers of bullets at ranges far greater than rifles or machine guns could attain – up to 6,500 ...
Upon detonation of the explosive, the casing disintegrates into extremely small particles, as opposed to larger pieces of shrapnel which results from the fragmentation of a metal shell casing. The HMTA powder acts like micro-shrapnel which is very lethal at close range (about 4 m or 13 ft), but loses momentum very quickly due to air resistance ...
This phenomenon allows the detonation gases to stream around the fragments or bypass them, reducing effective drive. Thus for metal shells that are brittle or have low ultimate strain, fragment velocities are typically about 80% of the value predicted by the Gurney formulas.
In one variation of this, the shot was held together by a coiled bar, and was spread by a fused charge in the same way as a shell. It was very effective against infantry, but its main shortcomings included very short range and ineffectiveness against infantry who had taken cover. Grapeshot was the starting point for the creation of shrapnel. [3]
