	Multi-Warhead, Anti-Armor Missile - United States Patent 4,638,737 McIngvale 27jan87
		Explosive bolts 84 have electrical leads 85 connected thereto for causing the explosive bolts to be severed and allow springs 86 to move halves 74 and 76 apart when desired to deploy subcaliber flechettes 22.
		It is understood that leads 85 of explosive bolts 84 and leads 64 of explosive bolts 58 are connected to the electronics of the missile for severing the bolts to cause deployment of subcaliber missiles 22 at the appropriate time.
		With the explosive bolts 84 released and nose sections 56 released, sections 50 pivot away from the missile due to high velocity windstream caught at the front of sections 50, pins 68 break, and fixture 72 moves outwardly to disperse subcaliber warheads 22.

		The Space Shuttle, as I recall, is "bolted" to the launch gantry with a large handful of them, which are blown to release it from the external supports during launch.
		"Explosive bolts" are very specific to each application- as noted, the "bolts" that jettison a fighter aircraft canopy can't be so powerful they throw shrapnel at the pilots.

		Explosive materials are used as "bursting charges" for bombs, missile warheads, grenades, and mines; and as "propellants" to fire bullets and artillery shells.
		As a propellant explosive, fl powder was used to fire balls from muskets, as well as stones from primitive cannon called "bombards", which eventually evolved into muzzle-loading artillery.
		PETN is a relatively sensitive explosive, and is often used as a booster, or in "detonating cord (detcord)", a type of explosive line used as a detonator and for specialized demolition tasks.

	Explosive bolts (Jordin Kare; Kim Keller; Henry Spencer)
		For all their hassles, explosives are a good way of >building lightweight hardware that functions firmly and positively, >because they can put a lot of energy into it for very little weight.
		Explosive bolts are not intended to explode, just to break firmly and reliably (although that invariably involves some amount of overkill).
		Because the bolts are torqued to a preset tension, the two ends spring away from each other when they are sheared.

		The explosive charge in turn set off an igniter, which sent a flame down the hollow core of the rocket motor to ignite the propellant.
		EED’s were also used in electro-explosive actuators, where the explosive force would move a mechanical lever, and in explosive bolts where the explosive force would break the bolt allowing parts to separate.
		Separation was achieved by firing explosive bolts, which released a clamp holding the third and fourth stages together.

		Huygens' explosive bolts (containing the same type of charges used in ejection seats) jettisoned the heat shield, flinging Huygens ~60 meters into the Titan air, briefly entangling in the still descending main parachute, and taking it with it.
		The purpose of the explosive is to blast the heat shield far away from Huygens.
		As said before, the bolts detach the shield from the lander, after which it is pushed away with a spring, which was "sandwiched" between lander and heatshield by the bolts holding the two together.

	Russian mishap threatens launch schedule - Space News - MSNBC.com
		A mishap during testing of such a craft, apparently involving the firing of an explosive bolt, may delay its launch to the international space station next month, according to Russian news reports.
		This apparently refers to the small explosive bolts that sever mechanical and electrical connections between sections of the Soyuz during landing.
		And if bolts from the same batch are also installed on the Soyuz currently docked to the space station, a significant effort will be required to requalify them or to develop contingency plans if one or more of them misfire on the planned return to Earth, now scheduled for Oct. 19 Moscow time.

	Gus Grissom vs. the Media: Victim or Hero?
		Although blastoff and re-entry went as expected, upon splashdown in the Atlantic Ocean, the 70 explosive bolts which held the hatch in place unexplainably exploded prematurely, forcing Gus to evacuate the capsule and swim for his life while the rescue helicopter frantically tried to save the capsule from sinking.
		Although his fellow astronauts supported him in every way, and the inquiry led to the eventual conclusion that the explosive hatch blew of its own accord, Gus never recovered his stature with the public or the media.
		Much to his chagrin, the exhaustive testing done on similar spacecraft with the same explosive bolts yielded no explanations for the premature explosion, as the bolts never again exploded prematurely in any testing.

		Aldrin arms the circuits to the circuits to the explosive bolts that will sever the ascent and descent stages just before the ascent engine's ignition.
		An explosive charge operates a guillotine that cuts through the connecting wiring and links between the two craft; and a ring of explosive bolts severs the final connection, allowing the service module to separate.
		The SM is jettisoned, leaving the CM weighing 12,250 pounds, one fifth of a percent of the original craft that lifted off the launch pad eight days previously, and the only part of Apollo 11 to return under controlled flight to earth.

		But the bolts are the most recent entries on a long list of shuttle parts that NASA either barely tested or did not test at all.
		Stray pieces of bolt are supposed to fall into structures called bolt-catchers, so the pieces don't hit the shuttle.
		The risk from the bolts is so great that the board will probably declare that NASA must fix them before any shuttle flies again.

	"I've got a fire in the cockpit!"
		Plus, the hatch, which under normal circumstances takes ninty seconds to open, and opens inward, as impossible to open in the fifteen seconds the crew was alive, and impossible to pull against the mounting pressure from the fire.
		In 1961, Gus Grissom's Mercury capsule, Liberty Bell 7, sank when the explosive bolts on the hatch blew prematurly, and randomly, without any action on his part (There was an investigation which found that they had infact just blown, and that Grissom was not at fault).
		Had there been explosive bolts on Apollo 1, one push of a button nd they would have been out of there, and Grissom, White and Chaffee might still be alive today.

	Star Wars: Databank \| Wookiee bowcaster
		Aside from Wookiees, there are only a small number of species capable of accurately controlling a bowcaster, as the weapon requires a great deal of strength to simply cock and fire, and its recoil is enough to level weaker beings.
		The quarrel is enveloped in energy that channels its explosive force directly into the target.
		The vine functions as a crude bowstring and can fire either energy quarrels or wooden crossbow bolts, although the weapon's maximum range is significantly reduced when using this primitive alternate mode.

	Russian docking device is getting a critical look
		One the issues involves the positioning of small explosive charges on the docking mechanism, which the United States is paying about $20 million to obtain for Atlantis.
		Earlier this year, NASA was surprised to learn that the Mir side was equipped with explosive charges on only the active hooks, while the shuttle side had the required charges on the active and passive mechanisms.
		However, in the event of multiple failures the two spacecraft could not separate after they had docked unless the explosive bolts can be discharged.

	Fuel system glitches delay shuttle launch
		The shuttle and the big fuel tank are linked by explosive bolts at three points.
		Eight-and-a-half minutes into flight, the empty tank is jettisoned as explosive fasteners under the forward fuselage and two on either side of the aft fuselage discharge.
		Immediately, springs pull the three 14-inch attachment bolts into special housings on the tank, and the shuttle fires thrusters to propel it safely away.

	Saltire : Blogging by Steve MacLaughlin
		According to Warren Zehner, a senior coordinator for the Environmental Protection Agency, which is overseeing collection of shuttle debris, the section of the shuttle's nose cone was found "reasonably intact." Zehner estimated the shuttle piece weighed about 500 pounds.
		From the nose cone section to finding parts resembling a door and windshield, and a warning about the presence of explosive bolts all point towards this conclusion.
		The explosive bolts may be from the hatch jettison mechanism or the left-hand flight deck overhead window jettison system.

	Third Level
		The first is known explosive chemicals that are designed and produced for use as an explosive (e.g., TNT, explosive bolts, bullets, blasting caps, and fireworks).
		Unlike known explosives, which are designed to be stable under normal conditions, PECs are particularly dangerous because they may explode if they are subjected to heat, light, friction, or mechanical shock.
		To handle and dispose of PECs properly, the University of California, Berkeley, campus uses a specialty contractor to transport the PEC to an isolated location where the chemical is opened by remote control.

		Also, there was the expert comment that a hatch contained by explosive bolts had NEVER deployed spontaneously so there was always some suspicion that he blew the hatch by mistake.
		In the early 60's that was tantamount to treason and it was almost considered more honorable if he had gone down with the capsule (he was in danger of drowning during the recovery).
		What is ignored in the film is that the explosive bolts were not the standard ones, but of a new design.
