	Space Shuttle
		On the launch pad, each SRB is fastened to the mobile launcher platform (MLP) at the SRB aft skirt by four large bolts that are severed by explosive charges at liftoff.
		This is contained within the SRB beginning with an 11-point star-shaped perforation in the forward segment to a double-truncated cone perforation in both of the aft segments and the aft closure segment.
		Milliseconds after SRB separation, 16 solid-fueled separation motors, four in the forward section and four in the aft skirt of each SRB, are fired briefly to help carry the SRBs away from the rest of the Shuttle.

		In addition, the two SRBs carry the entire weight of the external tank and orbiter and transmit the weight load through their structure to the mobile launcher platform.
		SRB impact occours in the ocean approximately 122 nautical miles (141 statute miles) downrange.
		The forward end of each SRB is attached to the external tank at the forward end of the SRB's forward skirt.

	Space Shuttle Solid Rocket Booster - Wikipedia, the free encyclopedia
		Seventy five seconds after SRB separation, SRB apogee occurs at an altitude of approximately 220,000 feet (67 km), after which they land on parachutes; impact occurs in the ocean approximately 122 nautical miles (226 km) downrange, after which the two are recovered.
		SRB separation is initiated when the three solid rocket motor chamber pressure transducers are processed in the redundancy management middle value select and the head-end chamber pressure of both SRBs is less than or equal to 50 lbf/in² (345 kPa).
		After the drogue chute has stabilized the SRB in a tail-first attitude, the frustum is separated from the forward skirt by a pyrotechnic charge triggered by the low-altitude baroswitch at a nominal altitude of 5,500 feet (1,676 m) about 243 seconds after SRB separation.

		SRB impact occurs in the ocean approximately 122 nautical miles (141 statute miles) downrange.
		Each booster is attached to the external tank at the SRB's aft frame by two lateral sway braces and a diagonal attachment.
		The propellant mixture in each SRB motor consists of an ammonium perchlorate (oxidizer, 69.6 percent by weight), aluminum (fuel, 16 percent), iron oxide (a catalyst, 0.4 percent), a polymer (a binder that holds the mixture together, 12.04 percent), and an epoxy curing agent (1.96 percent).

	Solid Rocket Boosters (SRBs)
		The two Solid Rocket Booster's (SRB's) provide the main thrust to the Space Shuttle during the lift-off and ascent stages, providing the system with 71.4 percent of the total thrust at lift-off.
		The SRB's support the entire weight of the orbiter and ET when they are attached to the mobile launch platform (MLP).
		The SRB's are recovered by two ships, the UTC Liberty and UTC Freedom, from the Atlantic and then are returned to Port Canaveral to be reprocessed and reprocessed for a future shuttle flight.

	WHOLLY WATER ® The Ultimate Drinking Water Appliance and whole house water filter systems by Life Streams ...
		A water heater provides a good environment for SRBs because it contains a "sacrificial anode." This anode is a magnesium rod that helps protect the water heater by corroding instead of the tank lining.
		SRBs are nourished by electrons released from the anode as it corrodes.
		SRBs die at temperatures of 140 degrees Fahrenheit or above, which is roughly equivalent to the medium setting on most home water heaters.

	SRBs (Dani Eder; Henry Spencer; Dennis R. Jenkins; Josh Hopkins)
		For a while there was work underway on filament- wound SRB casings, in which most of the casing would be a non-metallic composite material.
		The problem with one-piece SRBs is not the casings, but the handling difficulties of solid rockets 150 feet long weighing over a million pounds each.

		The SRBs are constructed in sections, which stacked on top of each other to form the completed booster rocket.
		The large solid rocket boosters on the Titan III were touted as evidence that the SRBs could be built cheaply and effectively, but there were major differences between the solid boosters of the Titan and the Space Shuttle SRBs.
		In the case of the SRBs, it was determined that the lower cost and greater risk or solids was a better choice that the higher cost and lesser risk of liquids.

		An igniter is installed in the forward segment and a nozzle in the aft segment.
		The SRBs come to life when the thrust vector control (TVC) system is activated, 28 seconds before launch.
		After the main engines are running, the boosters are ignited by an electrical spark that sends flames from the igniter down the center of the propellant.

	Revised EE/CA Draft Review
		The hydraulic pathways for the SRB are similar to the SAP in that the water typically flows downward through a bed of selected material.
		In the case of SRBs, the major maintenance requirement will be the removal of metal residues after the 30 year design life and the placement of a new media bed.
		The theory of SRB system performance is well understood and a number of full scale systems have been in successful operation for several years.

		These requirements are being phased in under the Clean Air Act Amendments of 1990 to protect the public from this air pollutant, which can cause potentially fatal respiratory illnesses, and to reduce the acidity of precipitation, which can slow the growth of forests and fish populations.
		To conduct their bioprocessing experiments, Kaufman and Selvaraj introduced into a vertical glass cylinder, or bioreactor, two types of bacteria-sulfate-reducing bacteria (SRBs), which cannot tolerate oxygen, and heterotrophs, which remove oxygen to help the SRBs survive.
		In the bioreactor, gelatin-like beads containing SRBs are suspended in sewage media through which sulfur dioxide flows.

		The SRB that probably caused the explosion suffered a 3% loss of power (about 100,000 pounds of thrust) seconds before.
		They might be able to jettison the SRBs, but it would be difficult to stay clear of them and the external tank.
		Maybe, if they had known about the SRB problem in time, if they had been able to get away from the SRBs and the ET, and been able to ditch successfully in the ocean.

		The two solid rocket boosters (SRBs) strapped to the space shuttle provide most of the thrust to lift a 4.5 million pound spacecraft off the ground.
		In the two minutes that the SRBs burn before they separate from the rest of the craft and fall away, the shuttle achieves a speed of 3,100 miles per hour and an altitude of 25 miles.
		The SRBs are 125 feet long, but a millimeter crack can cause a failure.

		Several studies have determined that reusing the SRBs is still cost effective, but the key point is that recovery and inspection of the SRBs is critical to flight safety.
		In the case of Challenger, the SRB did not suffer a catastrophic failure, but the leaking hot gas interacted with the rest of the vehicle, which resulted in the loss of Challenger and her crew.
		So, if there were a catastrophic failure of the SRB, like a case rupture, the internal pressure would be released and the remaining propellant would be expelled and burned at a slower rate.

		Currently I'm developing a filter driver because I need to intercept create/open/read/write operation on network drives and local drives, but if there is a way to do this using Win32 API, then I prefer to use the Win32 APIs than to write a filter driver.
		If they are custom devices with unknown SRB's then you could write a service or a driver which runs under administrative privileges which will forward request from a user mode app.
		The only disadvantage I detected (especially with 4.60) under XP is that calling the ASPI function to get the hostadapter info may deliver the hostadapter name without a terminating zero.
