NASA PR — Engineers at NASA’s Marshall Space Flight Center gave a key component of the J-2X engine a brisk workout to ensure it can withstand its extreme operating environment. The engine’s fuel turbopump first stage nozzle passed the test, performing even better than expected.
The J-2X is a highly efficient and versatile upper stage rocket engine that can stop and restart in space to support a variety of mission requirements. Full-scale testing begins later this summer but before then, engineers examined the longevity and durability of the engine’s fuel turbopump first stage nozzle. The nozzle directs hot gas flow onto the turbine blades.
