Space Shuttle Booster Separation Motors (BSM)
ATK is qualifying
a revised version of the Booster Separation Motors (BSM) for the Space Shuttle
that are designed to push the Reusable Solid Rocket Motors (RSRM) safely away
from the Shuttle's main liquid fuel tank and the Orbiter itself. At the time
of ignition, the BSMs are traveling through the atmosphere at more than 3,000
miles per hour and an altitude of approximately 24 nautical miles. There are
eight BSMs attached to each of the two RSRMs, four in the forward skirt and four
on the aft-skirt. All sixteen BSMs fire simultaneously to ensure a safe launch-to-orbit. |
