Rocket Boosters werebrought about aroundthe same time as spaceshuttles were, whichwas in 1982. Rocket Boosters are socrucial because theyprovide about 70% ofthe force needed to liftoff and into outer space.History of the RocketBooster
The rockets boosters weighs about 193,000 poundsempty, after it is filled with propellant it weighs atotal of 1.3 million pounds. During the launch sequence, the boosters exert all ofthe propellant before the space shuttle reaches analtitude of twenty four nautical miles, they detachfrom the main shuttle and fall back to Earth, land inan ocean, and are reused.BASIC FACTS
Solid Rocket boosters work on the idea of Newton’sthird law of motion, which is for every action there isan equal an opposite reaction. The rocket boosters exert a force, the propellant, onthe ground, which is the action, and in return therocket lifts off, an equal and opposite reaction. The main chemical equation for a rocket booster is10 Al+6NH4ClO > 5Al2O3+ 6HCL+3N2 +9H2OHow do SRB’s work?
The propellant consists of many things,including fuel, an oxidizer, a catalyst, abinder, and a curing agent. During the liftoff sequence, the rocketboosters exert around 2.65 million pounds ofpropellant.
The main engines of the shuttle are poweredby Fuel Cells. The fuel cells use Hydrogen and Oxygen toprovide electricity to the shuttle in a moreenvironmentally friendly way rather than useoil, which will eventually grow scarce.
