A slapper detonator, also called exploding foil initiator (EFI), is a detonator developed by Lawrence Livermore National Laboratory, US Patent No. 4,788,913 (Filed 1971, Granted 1988). It is an improvement over the earlier exploding-bridgewire detonator .
A new development is a slapper detonator, which uses thin plates accelerated by an electrically exploded wire or foil to deliver the initial shock. It is in use in some modern weapons systems. A variant of this concept is used in mining operations, when the foil is exploded by a laser pulse delivered to the foil by optical fiber.
The exploding-bridgewire detonator (EBW, also known as exploding wire detonator) is a type of detonator used to initiate the detonation reaction in explosive materials, similar to a blasting cap because it is fired using an electric current. EBWs use a different physical mechanism than blasting caps, using more electricity delivered much more ...
A detonator is a device used to trigger an explosive.
This mixture is used in the NASA Standard Initiator, [2] which is used to ignite various pyrotechnic systems, including the NASA standard detonator. [3] It yields rapid pressure rise, generates little gas, emits hot particles when ignited, is thermally stable, has long shelf life, and is stable under vacuum. It is sensitive to static electricity.
Hubbard, a big man with intense blue eyes and a five-o'clock shadow, greets me gruffly. "You don't look like Business Insider," he says. "You look like Rising S."
The 2024 college football season is officially over, so it's time to look ahead to what will happen in 2025. Here's our early Top 25 prediction.
The NASA Standard Initiator (NSI) is a pyrotechnic device used to set off other pyrotechnic devices. It is the central multi-purpose component of a modular system of detonating cords, pyrotechnics and various other explosive charges with many different uses.
