This Space Shuttle Solid Rocket Booster (SRB) model is a standard four segment
SRB, based on information publicly available at http://www.sworld.com.au/steven/space/shuttle/sim/,
As well as on Wikipedia, and at www.astronautix.com.
This table starts with a thrust of 3,060,000 lbs at no mass burned - which
is an immediate thrust. However, the buildup of 0.2 seconds gives a sine wave
ramp up of thrust from 0.0 to whatever the calculated value of thrust is.
