This dual-function valve can be opened by ground support equipment for the vent function during prelaunch and can open during flight when the ullage empty space pressure of the liquid hydrogen tank reaches 38 psig Sveriges Bästa Dejtingsajt 2018 Ansökan or the ullage pressure of the liquid oxygen tank Dejting Karlstad Quiz 25 psig kPa.
Another concept Dejtingsajt För Par Fotspår to use the ET as a cargo carrier for bulky payloads.
The tank was connected to each SRB at one forward attachment point using a crossbeam through the intertank and one aft bracket, and it was connected to the orbiter at one forward attachment bipod and two aft bipods.

Loads from the frames are then distributed through the barrel skin panels. Manufacture also included friction stir welding technology. The intermediate-diameter liquid hydrogen umbilical is a recirculation umbilical used only during the liquid hydrogen chill-down sequence during prelaunch.
Also, significant portions of the tank were milled differently so as to reduce thickness, and the weight of the ET's aft solid rocket booster attachments was reduced by using a stronger, yet lighter and less expensive titanium alloy.
These ring frames receive and distribute loads. Day ung dejtingsida gratis warm. Anomalies in foam application were so frequent that they were treated as variances, not safety incidents. The impact is believed to have damaged one comparatively large reinforced carbon-carbon panel on the leading edge of the left wing, believed to be about the size of a basketball which then allowed super-heated gas to enter the wing superstructure several days later during re-entry.

That piece of foam did not impact the orbiter. The External Tank was painted white for the first two Space Shuttle launches. Electrical signals and controls between the orbiter and the two solid rocket boosters were also routed through those umbilicals. When the SRBs are firing, the beam will flex due Dejting Karlstad Quiz high Dejtingsida Asiater Vitser loads.
These areas include the problematic bipod and PAL ramps, as well as some fittings and interfaces. Views Read Edit View history. The barrel sections are joined together by five major ring frames.

The ET thermal protection system consists primarily of spray-on foam insulation SOFIplus preformed foam pieces and premolded ablator materials.
Although all ETs produced after the introduction of the SLWT were of this configuration, one LWT remained in inventory to be used if requested Dejting Karlstad Quiz the end of the shuttle era. One of the liquid oxygen tank umbilical valves is for liquid oxygen, the other for gaseous oxygen. Unlike the Solid Rocket Boostersexternal tanks were not re-used. The original ET is informally known as the Standard Weight Tank SWT and was fabricated froma high-strength aluminum—copper alloy used for many aerospace applications.
This page was last edited on 3 Aprilat The ET has five propellant umbilical valves that interface with orbiter umbilicals: The aft Dejting Karlstad Quiz has a manhole fitting for access to the LH 2 feedline screen and a support fitting for the LH 2 feedline.
The baffle is Dejting Karlstad Quiz at the siphon outlet just above the aft dome of Dejting Karlstad Quiz LH 2 tank.

During SSME thrusting, the orbiter general-purpose computers constantly compute the instantaneous mass of the vehicle due to the usage of the propellants. The ET has three primary structures: Four pressure transducers located at the top of the liquid oxygen and liquid hydrogen tanks monitor the ullage pressures. Evening dejt 7 região free warm.
