WEST PALM BEACH, Fla., May 11, 2021 (Aerojet Rocketdyne PR) — Aerojet Rocketdyne recently completed a successful RL10C-X altitude hot fire test series that put the next generation engine through the rigors of a typical spaceflight mission. Using a test chamber that simulates the vacuum of outer space, the RL10C-X, which produces roughly 24,000 pounds of thrust, was tested in a flight-like configuration to demonstrate the engine’s capability to complete a typical mission profile, including multiple restarts.

The RL10C-X is the next evolution of the company’s RL10 upper-stage engine and contains major components – including the injector and combustion chamber – produced with the company’s industry-leading 3D printing technology.

STENNIS SPACE CENTER, Miss. (Aerojet Rocketdyne PR) — Today (April 12), the world’s most powerful hydrogen-fueled rocket engine built by Aerojet Rocketdyne, the RS-68A, completed its final hot-fire acceptance test for use on the United Launch Alliance (ULA) Delta IV Heavy launch vehicle on the B-1 Test Stand at NASA’s Stennis Space Center in Mississippi.
