On June 24, engineers completed a structural test of the Space Launch System (SLS) rocket for the Alsus to the moon, NASA announced. This test process is designed specifically for liquid oxygen structure test items to find their point of failure. The team must build test benches, support equipment and test items to test and analyze the data, a work that will help send American astronauts to the moon. The final test was a liquid oxygen tank, which is 70 feet high and 28 feet in diameter.
The huge tank was bolted to the 185,000-pound steel ring at the bottom of Marshall’s 4697 test stand. Hydraulic cylinders are calibrated and connected, enabling engineers to measure and record the effects of emission and flight forces. The team found that the liquid oxygen tank malfunctioned at the weld in its circumference, as engineers had predicted. The tank fails at the expected approximate load level, the test proves the flight readiness state, and provides the tank designer with key data.
The final test of the liquid oxygen structure test reached all planned milestones. The team working with the project said the successful SLS structural identification test at the Marshall Space Flight Center in Alabama ended the center’s most extensive testing since testing the space shuttle program 30 years ago. The test, which included five structural test items, went through 199 separate test cases and collected more than 421GB of data to be added to the computer model used to design the rocket.
