2. Pyrotechnic fastener - Wikipedia

   en.wikipedia.org/wiki/Pyrotechnic_fastener

   A pyrotechnic fastener (also called an explosive bolt, or pyro, within context) is a fastener, usually a nut or bolt, that incorporates a pyrotechnic charge that can be initiated remotely. One or more explosive charges embedded within the bolt are typically activated by an electric current, and the charge breaks the bolt into two or more pieces ...

3. Pyrotechnics - Wikipedia

   en.wikipedia.org/wiki/Pyrotechnics

   Pyrotechnics is the science and craft of creating such things as fireworks, safety matches, oxygen candles, explosive bolts and other fasteners, parts of automotive airbags, as well as gas-pressure blasting in mining, quarrying, and demolition. This trade relies upon self-contained and self-sustained exothermic chemical reactions to make heat ...

4. Frangible nut - Wikipedia

   en.wikipedia.org/wiki/Frangible_nut

   Frangible nut. The frangible nut is a component used in many industries, but most commonly by NASA [citation needed], to sever mechanical connections. It is, by definition, an explosively-splittable nut. The bolt remains intact while the nut itself is split into two or more parts. [ 1]

5. Marman clamp - Wikipedia

   en.wikipedia.org/wiki/Marman_clamp

   Marman clamp. A Marman clamp is a type of heavy-duty band clamp; it allows two cylindrical objects to be clamped together end-to-end with a ring clamp. It is sometimes also known as a "Marman ring". It consists of a circular strap with an interior V-shaped groove. Tension is applied to the strap with a threaded bolt and nuts connecting to the ...

6. Pyrotechnic composition - Wikipedia

   en.wikipedia.org/wiki/Pyrotechnic_composition

   A pyrotechnic composition is a substance or mixture of substances designed to produce an effect by heat, light, sound, gas/smoke or a combination of these, as a result of non-detonative self-sustaining exothermic chemical reactions. Pyrotechnic substances do not rely on oxygen from external sources to sustain the reaction.

7. Bridgewire - Wikipedia

   en.wikipedia.org/wiki/Bridgewire

   Bridgewire. A bridgewire or bridge wire, also known as a hot bridge wire ( HBW ), is a relatively thin resistance wire used to set off a pyrotechnic composition serving as pyrotechnic initiator. By passing of electric current it is heated to a high temperature that starts the exothermic chemical reaction of the attached composition.
