Encyclopedia: Pyrotechnics

Pyrotechnics is a field of study often thought synonymous with the manufacture of fireworks, but more accurately it has a wider scope that includes items for military and industrial uses. Items such as safety matches, oxygen candles, explosive bolts and fasteners and the automobile safety airbag all fall under the purview of pyrotechnics. Without pyrotechnics, modern aviation and spaceflight would be impracticable; this is because pyrotechnic devices combine high reliabilty with very compact and efficient energy storage: essentially in the form chemical energy which is converted via expanding hot gases often propagated by a shock wave as in bolt and cable cutters. The controlled action of a pyrotechnic device (initiated by any of several means, including an electrical signal, optical signal or mechanical impetus) makes possible a wide range of automated and/or remote mechanical actions; for example, deployment of safety equipment and services, precisely timed release sequences, etc. The majority of the technical pyrotechnic devices use propellants in their function, a minority use materials that are classified as primary or secondary explosives to obtain very fast and powerful mechanical (mostly cutting) actions; for example, Jet Axe.

Squib (explosive)

A squib is a small explosive about the size of a firecracker. It is often used to ignite a larger pyrotechnic explosive, such as a rocket engine. They are also widely used in the special effects industry to simulate a bullet hit on a person by coupling the squib itself with a packet of either fake...
