Detonation - Wikipedia
WebDetonation (from Latin detonare 'to thunder down/forth') is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it.
Detonation velocity - Wikipedia
WebExplosive velocity, also known as detonation velocity or velocity of detonation (VoD), is the velocity at which the shock wave front travels through a detonated explosive. Explosive velocities are always faster than the local speed of sound in the material. If the explosive is confined before detonation, such as in an artillery shell, the force ...
Engine knocking - Wikipedia
WebDetonation is characterized by an almost instantaneous, explosive ignition of at least one pocket of fuel/air mixture outside of the flame front. A local shockwave is created around each pocket, and the cylinder pressure will rise sharply – and possibly beyond its design limits – causing damage.
Detonation - Simple English Wikipedia, the free encyclopedia
WebDetonation is the explosion of an explosive. When an explosive detonates, it compresses the air around it, making a shock wave that can knock down buildings and kill people. The shock wave is made from the gases released when the explosive detonates.
Trinity (nuclear test) - Wikipedia
WebDecember 20, 1968. Trinity was the code name of the first detonation of a nuclear weapon, conducted by the United States Army at 5:29 a.m. MWT [a] (11:29:21 GMT) on July 16, 1945, as part of the Manhattan Project . The test was of an implosion-design plutonium bomb, nicknamed the "gadget", of the same design as the Fat Man bomb later detonated ...
Detonation - Wikiwand
WebDetonation is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations propagate supersonically through shock waves with speeds in the range of 1 km/sec and differ from deflagrations which have subsonic flame speeds in the ...
Table of explosive detonation velocities - Wikipedia
WebDetonation velocity is the speed with which the detonation shock wave travels through the explosive. It is a key, directly measurable indicator of explosive performance, but depends on density which must always be specified, and may be too low if the test charge diameter is not large enough.
Deflagration to detonation transition - Wikipedia
WebDeflagration to detonation transition (DDT) refers to a phenomenon in ignitable mixtures of a flammable gas and air (or oxygen) when a sudden transition takes place from a deflagration type of combustion to a detonation type of explosion.
Detonator - Wikipedia
WebA detonator, sometimes called a blasting cap in the US, is a small sensitive device used to provoke a larger, more powerful but relatively insensitive secondary explosive of an explosive device used in commercial mining, excavation, demolition, etc.
