  2. Space Shuttle Solid Rocket Booster - Wikipedia

    en.wikipedia.org/wiki/Space_Shuttle_Solid_Rocket...

    The Space Shuttle Solid Rocket Booster (SRB) was the first solid-propellant rocket to be used for primary propulsion on a vehicle used for human spaceflight. [1] A pair of them provided 85% of the Space Shuttle's thrust at liftoff and for the first two minutes of ascent.

  3. Solid rocket booster - Wikipedia

    en.wikipedia.org/wiki/Solid_rocket_booster

    A solid rocket booster (SRB) is a solid propellant motor used to provide thrust in spacecraft launches from initial launch through the first ascent. Many launch vehicles, including the Atlas V , [ 1 ] SLS and Space Shuttle , have used SRBs to give launch vehicles much of the thrust required to place the vehicle into orbit.

  4. SRB-A - Wikipedia

    en.wikipedia.org/wiki/SRB-A

    The original SRB-A was developed for the H-IIA rocket, and was used on its first 6 flights. It was derived from the SRB used on H-II.During the sixth launch of an H-IIA, one of the boosters failed to separate due to a leak of hot gasses eroding the detachment points, causing the rocket to fail to reach orbit.

  5. Solid-propellant rocket - Wikipedia

    en.wikipedia.org/wiki/Solid-propellant_rocket

    The Space Shuttle was launched with the help of two solid-fuel boosters known as SRBs. A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder. The inception of gunpowder rockets in warfare can be credited to the ...

    The cause of the disaster was the failure of the primary and secondary O-ring seals in a joint in the right Space Shuttle Solid Rocket Booster (SRB). The record-low temperatures on the morning of the launch had stiffened the rubber O-rings, reducing their ability to seal the joints.

    en.wikipedia.org/wiki/Graphite-Epoxy_Motor

    The Graphite-Epoxy Motor (GEM) is a family of solid rocket boosters developed in the late 1980s and used since 1990. GEM motors are manufactured with carbon-fibre-reinforced polymer casings and a fuel consisting of HTPB-bound ammonium perchlorate composite propellant.

  9. Epsilon (rocket) - Wikipedia

    en.wikipedia.org/wiki/Epsilon_(rocket)

    Epsilon's first stage has been the modified SRB-A3 which is the solid-rocket booster of H-IIA. As the H-IIA is to be decommissioned and to be replaced by H3, Epsilon is to be replaced by a new version, named Epsilon S. [21] Major changes of Epsilon S from Epsilon are: [21] The first stage is based on SRB-3, the strap-on solid-rocket booster of H3.
