The detonation velocity values presented here are typically for the highest practical density which maximizes achievable detonation velocity. [1] The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation ...
Potassium nitrate/magnesium flash powder should be mixed and used immediately and not stored due to its tendency of self-ignition. If magnesium is not a very fine powder, it can be passivated with linseed oil or potassium dichromate. The passivated magnesium flash powder is stable and generally safe to store. 2 KNO 3 + 5 Mg → K 2 O + N 2 + 5 MgO
Today, velocity of detonation can be measured with accuracy. Together with density it is an important element influencing the yield of the energy transmitted for both atmospheric over-pressure and ground acceleration. By definition, a "low explosive", such as black powder, or smokeless gunpowder has a burn rate of 171–631 m/s. [15]
Gas explosions can either deflagrate or detonate based on confinement; detonation velocities are generally around 1700 m/s [3] [4] [5] but can be as high as 3000 m/s. [6] Solid explosives often have detonation velocities ranging beyond 4000 m/s to 10300 m/s. Detonation velocity can be measured by the Dautriche method.
Detonation (from Latin detonare 'to thunder down/forth') [1] 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.
Propellants using nitrocellulose (detonation velocity 7,300 m/s (23,950 ft/s), RE factor 1.10) (typically an ether-alcohol colloid of nitrocellulose) as the sole explosive propellant ingredient are described as single-base powder.
As a simple approximate equation, the physical value of is usually very close to 1/3 of the detonation velocity of the explosive material for standard explosives. [1] For a typical set of military explosives, the value of D 2 E {\displaystyle {\frac {D}{\sqrt {2E}}}} ranges from between 2.32 for Tritonal and 3.16 for PAX-29n.
