Pyrotechnic fastener (original) (raw)
Pyrobolzen (auch: Sprengbolzen) sind kontrolliert trennbare Verbindungen. Dazu wird innerhalb dieses Bolzens eine kleine Sprengladung gezündet, ohne dass dabei umherfliegende Splitter entstehen. Sie werden zum Beispiel zum Abtrennen von Bauteilen in der Raumfahrt oder zum Abwerfen von externen Treibstofftanks an Kampfflugzeugen eingesetzt. Alternativ werden auch Schneidladungen zum Abtrennen von Raketenstufen verwendet.

(fr) 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 through fiber-optic cables, which subsequently fire the main charge. Gas generators are similar to pyrotechnic fasteners. They are used to generate large amounts of gas, as for turbopumps, to inflate balloons, especially airbags, to eject parachutes and similar applications. (en) 分離ボルト（ぶんりボルト、英語：explosive bolt）とは火工品の一種で別名爆裂ボルト、爆砕ボルト、爆発ボルトとも呼ばれる。 ボルトの中を中空にしてそこに爆薬を充填し、電気雷管を埋め込んだ物である。起爆すると切断面から断裂し真っ二つに折れることで部品の固定を解く。 周囲を傷つけないように破片の飛び散らないタイプもある。爆轟型の他に燃焼型もあるが海外では動作が確実な爆轟型が大半であり、燃焼型は主に爆薬を用いることが法規制上困難な場合などに用いられる。 (ja) Un bullone esplosivo è un dispositivo per fissare e all'occorrenza rilasciare all'istante due parti meccaniche. In pratica, si tratta di un bullone con del materiale esplosivo incorporato. Questa carica viene fatta esplodere da remoto, solitamente con un impulso elettrico, e ha la funzione di distruggere il bullone stesso. Distrutto quest'ultimo, infatti, le due parti precedentemente fissate tornano libere di separarsi. Questo meccanismo di fissaggio e rilascio rapido è usato spesso in astronautica, ad esempio nella separazione degli stadi dei razzi vettori, in quanto più leggero e molto più affidabile dei fermi meccanici. Anche in aviazione trova largo impiego, per esempio per far saltare il tettuccio della carlinga in caso di emergenza. Più recentemente, è possibile utilizzare diodi laser per far esplodere detonatori attraverso fibre ottiche.
