The Space Shuttle external tank (ET) was the component of the Space Shuttle launch vehicle that contained the liquid hydrogen fuel and liquid oxygen oxidizer. During lift-off and ascent it supplied the fuel and oxidizer under pressure to the three RS-25 main engines in the orbiter. The ET was jettisoned just over 10 seconds after main engine ...
During cryo-filling of the Space Shuttle External Tank (ET) with liquid hydrogen and liquid oxygen prior to the first launch attempt on 6 December 2007, two of four LH2 ECO sensors failed a test. Mission rules called for at least three of the four sensors to be in working order for a launch attempt to proceed.
The Space Shuttle external tank (ET) carried the propellant for the Space Shuttle Main Engines, and connected the orbiter vehicle with the solid rocket boosters. The ET was 47 m (153.8 ft) tall and 8.4 m (27.6 ft) in diameter, and contained separate tanks for liquid oxygen and liquid hydrogen.
The RS-25 engine consists of pumps, valves, and other components working in concert to produce thrust. Fuel (liquid hydrogen) and oxidizer (liquid oxygen) from the Space Shuttle's external tank entered the orbiter at the umbilical disconnect valves and from there flowed through the orbiter's main propulsion system (MPS) feed lines; whereas in the Space Launch System (SLS), fuel and oxidizer ...
Space Shuttle 7.6 and 10.6 Fairing. DARPA studied modifying the current external tank design to be able to carry low-density payloads in a 25 or 35 ft (7.6 or 10.6 m) diameter fairing where the oxygen tank was currently. The Shuttle on average would only fly 66% of its payload capability but at nearly 100% of its payload volume.
Cutaway of Space Shuttle external tank. Autogenous pressurization is the use of self-generated gaseous propellant to pressurize liquid propellant in rockets.Traditional liquid-propellant rockets have been most often pressurized with other gases, such as helium, which necessitates carrying the pressurant tanks along with the plumbing and control system to use it.
At long last, the final journey of the last space shuttle ever built, Endeavour, and its giant orange external tank are expected to begin this month — the capstone to a historic journey to an ...
The booster's 14 engines would be located in clusters of seven, at the bottom of both halves of the booster. Unlike the final design for the Space Shuttle, the Spacemaster would lack an external tank, and the boosters would be joined, by means of connecting struts which would also serve as the mounting for the orbiter.
