detoneerimiskiiruse

Detoneerimiskiirus, also known as detonation velocity, is a fundamental property of explosives. It represents the speed at which the detonation wave propagates through the explosive material. This high-speed wave is a self-propagating decomposition process that generates intense heat and pressure, leading to the explosive's destructive effect.

Detonation velocity is typically measured in meters per second (m/s) and varies significantly depending on the specific explosive compound. Factors influencing this velocity include the chemical composition, density, crystal structure, and confinement of the explosive material. Generally, more sensitive and powerful explosives exhibit higher detonation velocities. For instance, nitroglycerin has a detonation velocity of around 7,700 m/s, while TNT is approximately 6,900 m/s.

Understanding detonation velocity is crucial in various applications, including military ordnance design, mining, and demolition. It helps engineers predict the behavior of explosives, calculate the energy release, and design safe and effective explosive charges. The phenomenon is distinct from deflagration, which is a slower, subsonic combustion process. Detonation is characterized by a supersonic shock wave that triggers the chemical reaction.
