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 ...
The Chapman–Jouguet condition holds approximately in detonation waves in high explosives. 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.
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 ...

Tertiary explosives, also called blasting agents, are so insensitive to shock that they cannot be reliably detonated by practical quantities of primary explosive, and instead require an intermediate explosive booster of secondary explosive. These are often used for safety and the typically lower costs of material and handling.
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 .
