Pyrotechnic
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, light, gas, smoke and/or sound. The name comes from the Greek words ''pyr'' ("fire") and ''tekhnikos'' ("made by art"). People responsible for the safe storage, handling, and functioning of pyrotechnic devices are known as pyrotechnicians. Proximate pyrotechnics Explosions, flashes, smoke, flames, fireworks and other pyrotechnic-driven effects used in the entertainment industry are referred to as proximate pyrotechnics. Proximate refers to the pyrotechnic device's location relative to an audience. In the majority of jurisdictions, special training and licensing must be obtained from local authorities to legally prepare and use proximate ...

Pyrotechnician
Pyrotechnicians are people who are responsible for the safe storage, handling, and functioning of pyrotechnics and pyrotechnic devices. Although the term is generally used in reference to individuals who operate pyrotechnics in the entertainment industry, it can include all individuals who regularly handle explosives. However, individuals who handle more powerful materials for commercial, demolition, or military applications are generally referred to as explosive technicians. Certification It is becoming common in many countries and regions for individuals involved with the storage, handling, and operation of pyrotechnics to have some form of license or certification. The specific requirements for certification, along with any restrictions or prohibitions can vary from one jurisdiction to the next. Most jurisdictions do require some type of minimum professional fireworks training before being allowed to apply for certification. Australia In Australia, individuals using, handling ...

Fireworks
Fireworks are a class of low explosive pyrotechnic devices used for aesthetic and entertainment purposes. They are most commonly used in fireworks displays (also called a fireworks show or pyrotechnics), combining a large number of devices in an outdoor setting. Such displays are the focal point of many cultural and religious celebrations. Fireworks take many forms to produce four primary effects: noise, light, smoke, and floating materials ( confetti most notably). They may be designed to burn with colored flames and sparks including red, orange, yellow, green, blue, purple and silver. They are generally classified by where they perform, either 'ground' or 'aerial'. Aerial fireworks may have their own propulsion ( skyrocket) or be shot into the air by a mortar (aerial shell). Most fireworks consist of a paper or pasteboard tube or casing filled with the combustible material, often pyrotechnic stars. A number of these tubes or cases may be combined so as to make whe ...

Flare
A flare, also sometimes called a fusée, fusee, or bengala in some Latin-speaking countries, is a type of pyrotechnic that produces a bright light or intense heat without an explosion. Flares are used for distress signaling, illumination, or defensive countermeasures in civilian and military applications. Flares may be ground pyrotechnics, projectile pyrotechnics, or parachute-suspended to provide maximum illumination time over a large area. Projectile pyrotechnics may be dropped from aircraft, fired from rocket or artillery, or deployed by flare guns or handheld percussive tubes. History The earliest recorded use of gunpowder for signaling purposes was the 'signal bomb' used by the Chinese Song Dynasty (960–1279) as the Mongol-led Yuan Dynasty (1271–1368) besieged Yangzhou in 1276. These soft-shelled bombs, timed to explode in midair, were used to send messages to a detachment of troops far in the distance. Another mention of the signal bomb appears in a text dating ...

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. The bolt is typically scored around its circumference at the point(s) where the severance should occur. Such bolts are often used in space applications to ensure separation between rocket stages, because they are lighter and much more reliable than mechanical latches. In applications that require safety, precision and reliability, such as the aerospace industry, pyrotechnic fasteners are triggered using exploding bridgewire detonators, which were themselves later succeeded by slapper detonators. Classical blasting caps are generally avoided for such usage. More recent developments have used pulsed laser diodes to detonate initiators t ...

Rammstein
Rammstein (, "ramming stone") is a German Neue Deutsche Härte band formed in Berlin in 1994. The band's lineup—consisting of lead vocalist Till Lindemann, lead guitarist Richard Kruspe, rhythm guitarist Paul Landers, bassist Oliver Riedel, drummer Christoph Schneider, and keyboardist Christian "Flake" Lorenz—has remained unchanged throughout their history, along with their approach to songwriting, which consists of Lindemann writing and singing the lyrics over instrumental pieces the rest of the band has completed beforehand. Prior to their formation, some members were associated with the punk rock acts Feeling B and First Arsch. After winning a local contest, Rammstein was able to record demos and send them to different record labels, eventually signing with Motor Music. Working with producer Jacob Hellner, they released their debut album '' Herzeleid'' in 1995. Though the album initially sold poorly, the band gained popularity through their live performances and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bullet Hit Squib
A bullet hit squib or a blood squib is a practical, pyrotechnic special effect device used in the film industry, theatre productions and first responder moulage training to simulate a bullet wound spurting blood. Typically, the effect is carried out with clothing instead of on bare skin in order to conceal the device. Even if the portrayal is not necessarily accurate or is exaggerated compared to real-life (in the example of the main figure, blood spews out of a thick coat while emitting smoke), filmmakers and the audience have become accustomed to associating this aesthetic with a gunshot wound. A bullet hit squib device comprises a squib (a small, firecracker-like explosive), an electric match, a small pack of simulant (most commonly fake blood), a protective plate and some padding attached to the actor's costume. The device is then connected to a battery and a remote, with which the squib can be triggered by the actor or a crew member, creating the visual effect of a gu ...

Airbag
An airbag is a vehicle occupant-restraint system using a bag designed to inflate extremely quickly, then quickly deflate during a collision. It consists of the airbag cushion, a flexible fabric bag, an inflation module, and an impact sensor. The purpose of the airbag is to provide a vehicle occupant with soft cushioning and restraint during a collision. It can reduce injuries between the flailing occupant and the interior of the vehicle. The airbag provides an energy-absorbing surface between the vehicle's occupants and a steering wheel, instrument panel, body pillar, headliner, and windshield. Modern vehicles may contain up to 10 airbag modules in various configurations, including: driver, passenger, side-curtain, seat-mounted, door-mounted, B and C-pillar mounted side-impact, knee bolster, inflatable seat belt, and pedestrian airbag modules. During a crash, the vehicle's crash sensors provide crucial information to the airbag electronic controller unit (ECU), including coll ...

Safety Matches
A match is a tool for starting a fire. Typically, matches are made of small wooden sticks or stiff paper. One end is coated with a material that can be ignited by friction generated by striking the match against a suitable surface. Wooden matches are packaged in matchboxes, and paper matches are partially cut into rows and stapled into matchbooks. The coated end of a match, known as the match "head", consists of a bead of active ingredients and binder, often colored for easier inspection. There are two main types of matches: safety matches, which can be struck only against a specially prepared surface, and strike-anywhere matches, for which any suitably frictional surface can be used. Because of the substance used to coat each match, this makes them non-biodegradable. Etymology Historically, the term ''match'' referred to lengths of cord (later cambric) impregnated with chemicals, and allowed to burn continuously. These were used to light fires and fire guns (see matchlock) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerb (pyrotechnic)
A gerb is a type of firework which produces a jet of sparks, usually lasting between 15 and 60 seconds. It is a thick-walled tube filled with pyrotechnic composition and possessing a choke, which is a narrowing in the tube. Gerbs are often referred to as 'fountains' (spark fountain). Sometimes a small charge of black powder is added to the bottom of a gerb to make it finish with a bang: this charge is known as the 'bounce'. These are commonly used at sporting events. Gerbs intended for use indoors near a proximate audience, such as at a rock concert, typically have shorter durations (from {{frac, 1, 8 to 30 seconds) and heights (4 to 50 feet). Gerbs are usually measured in terms of time and height. For example, a 4×4 burns for 4 seconds at a height of 4 feet. Eric Newby's book ''The Last Grain Race ''The Last Grain Race'' is a 1956 book by Eric Newby, a travel writer, about his time spent on the four-masted steel barque ''Moshulu'' during the vessel's last voyage in the Au ...

Saxon (firework)
{{other uses, Saxon (other) The Saxon is a rapidly spinning ground-based firework that is basic in design and construction. There are slight variations but typically the Saxon consists of two tubes which are filled with composition and have a clay plug at the end. They are joined in the centre by wooden dowel and pivot at point in the middle. It is driven by exhaust or vents located on the sides of the tube near the end plugs which are at right angles to the tube axis.
