RS-25 fires up again in another controller test for SLS

RS-25 Rocket Engine Test

NASA

Опубликовано: 9 авг. 2017 г.

The 8.5-minute test conducted at NASA's Stennis Space Center is part of a series of tests designed to put the upgraded former space shuttle engines through the rigorous temperature and pressure conditions they will experience during a launch. The tests also support the development of a new controller, or "brain," for the engine, which monitors engine status and communicates between the rocket and the engine, relaying commands to the engine and transmitting data back to the rocket.

NASA on a Strong Roll in Preparing Space Launch System Flight Engines

[свернуть]

NASA is on a roll when it comes to testing engines for its new Space Launch System (SLS) rocket that will send astronauts to deep-space destinations, including Mars. Just two weeks after the third test of a new RS-25 engine flight controller, the space agency recorded its fourth full-duration controller test Aug. 9 at Stennis Space Center near Bay St. Louis, Mississippi. Engineers conducted a 500-second test of the RS-25 engine controller on the A-1 Test Stand at Stennis. The test involved installing the controller on an RS-25 development engine and firing it in the same manner, and for the same length of time, as needed during an actual SLS launch. The test marked another milestone toward launch of the first integrated flight of the SLS rocket and Orion crew vehicle. Exploration Mission-1 will be an uncrewed mission into lunar orbit, designed to provide a final check-out test of rocket and Orion capabilities before astronauts are returned to deep space. The SLS rocket will be powered at launch by four RS-25 engines, providing a combined 2 million pounds of thrust, and with a pair of solid rocket boosters, providing more than 8 million pounds of total thrust. The RS-25 engines for the initial SLS flights are former space shuttle main engines that are now being used to launch the larger and heavier SLS rocket and with the new controller. The controller is a critical component that operates as the engine "brain" that communicates with SLS flight computers to receive operation performance commands and to provide diagnostic data on engine health and status. Engineers conducted early prototype tests at Stennis to collect data for development of the new controller by NASA, RS-25 prime contractor Aerojet Rocketdyne and subcontractor Honeywell. Testing of actual flight controllers began at Stennis in March. NASA is testing all controllers and engines designated for the EM-1 flight at Stennis. It also will test the SLS core stage for the flight at Stennis, which will involve installing the stage on the B-2 Test Stand and firing its four RS-25 engines simultaneously, as during an actual launch. RS-25 tests at Stennis are conducted by a team of NASA, Aerojet Rocketdyne and Syncom Space Services engineers and operators. Aerojet Rocketdyne is the RS-25 prime contractor. Syncom Space Services is the prime contractor for Stennis facilities and operations.

Just two weeks after conducting another in a series of tests on new RS-25 rocket engine flight controllers for NASA's Space Launch System (SLS) rocket, engineers at NASA's Stennis Space Center in Mississippi completed one more hot-fire test of a flight controller on August 9, 2017. With the hot fire, NASA has moved a step closer in completing testing on the four RS-25 engines which will power the first integrated flight of the SLS rocket and Orion capsule known as Exploration Mission 1.

RS-25 Main Engine Controllers Tested for SLS Debut

STENNIS SPACE CENTER, Miss., Aug. 09, 2017 (GLOBE NEWSWIRE) -- Today at NASA's Stennis Space Center, Aerojet Rocketdyne, a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE:AJRD), tested its fourth RS-25 engine controller needed for the inaugural flight of NASA's Space Launch System (SLS) during Exploration Mission-1 (EM-1). Slated to debut in 2019, SLS will be the world's most powerful and versatile rocket.

"The SLS rocket will enable missions no other current rocket can, such as landing humans on Mars and sending large science payloads to other planets in record time," said Aerojet Rocketdyne CEO and President Eileen Drake. "This is the rocket the nation will rely on for decades."

Four RS-25 main engines built by Aerojet Rocketdyne provide more than two million pounds of thrust for the first stage of the SLS rocket. These are the world's most reliable rocket engines with 14 of 16 assigned to the SLS program having previously flown on the Space Shuttle. NASA and Aerojet Rocketdyne are testing the RS-25 engines to confirm they can withstand the SLS flight environment as well as certifying the new engine controllers.

New engine controllers are a central technology upgrade that these engines are receiving. These controllers weigh less, use less power and have fewer parts, but are more robust than their shuttle era counterparts and provide two times the reliability. The flight controller is the "brain" of the engine, translating the vehicle's commands into action while monitoring the health of the engine.

"The upgraded RS-25 engines are just one example of how the country is preparing a new course for deep space exploration," said Dan Adamski, RS-25 program director at Aerojet Rocketdyne. "EM-1 is the first step in a new roadmap to explore the solar system."

EM-1 is the first launch of the SLS and upgraded RS-25 engines; it is also the first integrated test of SLS and the Orion spacecraft. During the three-week mission, the Orion spacecraft will travel in a distant retrograde orbit around the moon and return safely back to Earth.

Aerojet Rocketdyne is an innovative company delivering solutions that create value for its customers in the aerospace and defense markets. The company is a world-recognized aerospace and defense leader that provides propulsion and energetics to the space, missile defense and strategic systems, tactical systems and armaments areas, in support of domestic and international markets.
