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 ...
Typical detonation velocities for organic dust mixtures range from 1400 to 1650 m/s. [2] 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.
V or V m - Velocity of accelerated flyer after explosive detonation N - The mass of a tamper shell or sheet on the other side of the explosive charge, if present - The energy per mass of an explosive that ends up as kinetic energy - The Gurney constant for a given explosive. This is expressed in units of velocity (millimeters per microsecond ...
It states that the detonation propagates at a velocity at which the reacting gases just reach sonic velocity (in the frame of the leading shock wave) as the reaction ceases. [ 1 ] [ 2 ] David Chapman [ 3 ] and Émile Jouguet [ 4 ] originally (c. 1900) stated the condition for an infinitesimally thin detonation.
High explosives (HE, or high-order explosives) are explosive materials that detonate, meaning that the explosive shock front passes through the material at a supersonic speed. High explosives detonate with explosive velocity of about 3–9 kilometres per second (9,800–29,500 ft/s). For instance, TNT has a detonation (burn) rate of ...
Detonation is more destructive than deflagrations. In detonation, the flame front travels through the air-fuel faster than sound; while in deflagration, the flame front travels through the air-fuel slower than sound. Detonations occur in both conventional solid and liquid explosives, [3] as well as in reactive gases. TNT, dynamite, and C4 are ...
It was also used for the explosive lenses in the first implosion-type nuclear weapons developed by the United States. [ 2 ] [ 3 ] The standard proportions of ingredients (by weight) are 59.5% RDX ( detonation velocity of 8,750 m/s) and 39.5% TNT (detonation velocity of 6,900 m/s), phlegmatized with 1% paraffin wax .

Astrolite A, a secondary (and less common) type of Astrolite, is sensitized by the addition of finely powdered aluminium to the Astrolite G mixture. Though it has a lower detonation velocity (approximately 7,600 m/s) than Astrolite G, the addition of the aluminium increases both its density and explosive brisance, moderately increasing its overall effectiveness/RE Factor.
