	Solid rocket booster - Wikipedia, the free encyclopedia
		A solid rocket booster (SRB) is used to provide the main thrust in spacecraft launches from the launchpad up to an altitude of about 45 kilometres.
		One example of the increased performance from SRBs is the Ariane 4 rocket.
		Solid rocket motors cannot easily be turned off or have their thrust terminated during flight, which is a risk factor for manned spacecraft.

	ORDERING INFORMATION
		Once these were finished they were glued to the rocket so that the seam was aligned with the centerline of the booster and so that the leading tip is even with the leading edge of the side tubes.
		The booster’s glider mount consists of 2 trapezoidal pieces of thin stock around the pin and pin holder, that was cut with templates from the thicker 1/8” stock.
		The shock cord is mounted to the booster in the typical MPC manner.

	Water Rocket Computer Model - 2 Stage Optimisation
		A two stage rocket is essentially two rockets that interact with each other - the speed achieved by the booster dependent upon the weight of the sustainer and the weight of water carried by the sustainer - the process of optimisation being one of reiteration.
		Noting down the height speed and angle of an optimised booster flight and transferring these details to the sustainer, only to produce a different weight for the booster to carry on the next iteration can be time consuming, especially if you are trying to find the best nozzle size for the sustainer as well.
		The sustainer and booster release their grip (the differential pressure between the sustainer and the booster allows the crushing sleeve to expand, releasing its grip on the sustainer nozzle, or the expanded tube to collapse); and,

		The failure of the O-ring was attributed to several factors, including faulty design of the solid rocket boosters, insufficient low- temperature testing of the O-ring material and the joints that the O-ring sealed, and lack of proper communication between different levels of NASA management.
		The failure of the O-ring was attributed to several factors, including faulty design of the solid rocket boosters, insufficient low temperature testing of the O-ring material and the joints that the O-ring sealed, and lack of communication between different levels of NASA management.
		The size of the gap is controlled by several factors, including the dimensional tolerances of the metal cylinders and their corresponding tang or clevis, the ambient temperature, the diameter of the O-ring, the thickness of the shims, the loads on the segment, and quality control during assembly.

	Shuttle Booster Rocket Recovery
		That unexpected extension, which will force later scheduled missions, was because replacements would be needed for the two solid-fuel booster rockets scheduled to be used for the launch of the shuttle "Atlantis" on a retrieval mission to return the woman astronaut to earth at the completion of her assigned mission.
		During the initial lift-off phase of the launch, two 15-story shuttle booster rockets (SRBs) -- each containing rubbery, highly explosive fuel -- located on left and right sides of the main rocket engine, are also ignited to provide an additional powerful kick to send the shuttle up and away from the launch site.
		Attached to the main rocket -- firing in conjunction with it for liftoff -- both SRBs separate from the rocket at a predetermined time in the flight path and start return to the surface, with landing planned for 100 miles at sea.
