NASA A new series of tests for the production of RS-25 engines was conducted for the first time on January 28, 2021, which would help power the agency’s space launch system (SLS) Rockets on future deep space missions.
The test of the RS-25 developmental engine number 0528 marks the beginning of a seven-test series at the A-1 test stand at the Stannis Space Center near Bay-1 Louis, Missouri, providing valuable data to the Aerojet Rocketdine, lead contractor For SLS engines designed to do as the company begins production of the new RS-25 engine.
Four RS-25 engines help the SLS at launch, with a combined 1.6 million pounds thrust during launch and 2 million pounds during thrust. The RS-25 locomotives for the first four SLS flights have been upgraded as space shuttle main engines and have completed certification testing. NASA is now focused on providing data to increase production of components for use on new RS-25 engines and subsequent SLS missions.
The new test series will evaluate the performance of engine components built with state-of-the-art manufacturing technologies and techniques. The test is part of NASA and part of Aerojet Rocketdyne’s effort to use advanced manufacturing methods to reduce the cost and time required to build the new RS-25 engine.
For the January 28 test, the RS-25 developmental engine was fired for the entire duration of approximately eight and a half minutes (500 seconds), to help send the SLS into orbit should the engine fire at the same time. The engine was fired at 111% of its original space shuttle main engine design power and the same power level was required to help launch the SLS in its missions.
The hot fire marks the first test at a historic stand since April 2019, when NASA completed testing of RS-25 engines for the first four SLS missions. Since that time, Stannis teams have worked on major maintenance and projects to upgrade the A-1 test stand and its systems to ensure future testing capabilities.
The work, among other projects, led to the installation of a new NASA-designed-and-built thrust vector control system on the test stand, which allows operators to “gimbal” test RS-25 engines, taking them on a tight circular axis. should go. To ensure proper trajectory in flight.
NASA is making SLS the world’s most powerful rocket. Initial SLS missions will fly to the moon as part of NASA’s Artemis program, including this year’s Artemis Eye Unwanted Test Flight with astronauts to explore the lunar surface and prepare for missions of the future. Will pave the way for flights. Mars.
The RS-25 tests at Stannis are conducted by a joint team of NASA, Aerojet Rocketdyne and Sincom Space Services operators. Syncom Space Services is the prime contractor for Stennis facilities and operations.
