Successful NASA Test of Rocket Fuel Tank Ends With a Bang

11 Décembre, 2019, 08:40 | Auteur: Therese Cote

According to reports, with the tank passing its test, the SLS has moved beyond the assembly and testing stage.

At NASA's Marshall Space Flight Center in Huntsville, Alabama, engineers pushed the test tank full of liquid hydrogen way past its limits.

Boeing, which is the primary contractor on the SLS project, performed its own stress tests on the tank prior to NASA's tests.

Such was the case on December 5 when engineers put a replica of the world's largest fuel tank, NASA's Space Launch System liquid hydrogen tank, through a rigorous pressure test that literally blew it apart to see how much stress it could take. NASA has said that for the first mission of SLS and Orion, Artemis I, the rocket is capable of sending more than 26 metric tons (57,000 pounds) to the Moon. The tank could withstand more than 260% of expected flight loads before rupturing. NASA unveiled on December 9 the core stage of the SLS moon rocket, which will also be used in the Artemis program. During these earlier tests, the tank showed no signs of cracking or breaking at all.

Drew Lock looks like answer to Broncos' fans prayers
Sunday's win was the first time the Broncos had a defensive touchdown in any game since that win over the Cardinals. First, it was the offensive, with rookies Drew Lock and Noah Fant illuminating Houston's defense in the air game.

"The initial tank buckling failure occurred at the same relative location as predicted by the Boeing analysis team and initiated within 3% of the predicted failure load", said Luke Denney, qualification test manager for Boeing's Test & Evaluation Group.

For all of these tank tests, both NASA and Boeing engineers simulated a liftoff with the flight stresses that come along with that.

For about five hours, the test tank was subjected to vast loads coming from pressurized nitrogen gas and hydraulic pistons that squeezed it with the force of millions of pounds. "This data will benefit all aerospace companies designing rocket tanks". First, build a stand specifically for that goal with enough design flexibility it can be reused, then install strain sensors on the tank, lots of them, add a safe fuel stand-in and apply pressure.
