NASA Stennis Space Center
NASA marked the first RS-25 engine test of the year on Feb. 13 on the A-1 Test Stand at Stennis Space Center. This test, featured a flight controller that will serve as the RS-25 avionics for missions. It was also the third time NASA has powered an RS-25 engine to 113 percent of original thrust level. The hot fire test also continued testing of two engine components – a 3D-printed pogo accumulator to dampen pressure oscillations that can cause flight instability and a main combustion chamber fabricated using a new hot isostatic pressing (HIP) bonding technique. Aerojet is making both components with innovative techniques that saves considerable time and money.
