Aerojet Rocketdyne and the U.S. Air Force have revised an existing agreement supporting development of a new large rocket engine to include work on an updated version of an upper stage engine.
The U.S. Air Force and Aerojet Rocketdyne are working to revise an agreement to support development of the company's AR1 rocket engine, as questions continue about the engine's long-term future.
Aerojet Rocketdyne’s success in developing AR1, an engine designed to replace Russian-made RD-180 engines on United Launch Alliance rockets, hinges in part on its use of Mondaloy, a nickel-based superalloy invented in the 1990s by metallurgists Monica Jacinto.
ASRC of Beltsville, Md., has test fired a subscale propellant injector built via additive manufacturing, or 3D printing, paving the way for a version that will be able to support whichever engine United Launch Alliance chooses to replace the Russian-built RD-180 on the Atlas 5 rocket.
Research and development (R&D) costs for the AR1 rocket from the program’s inception through June 30 have reached about $228 million, according to recent Security Exchange Commission (SEC) filings by Aerojet Rocketdyne, the engine's manufacturer.
An independent assessment of rocket engine development delivered to a House committee last week has concluded that Blue Origin remains well ahead of Aerojet Rocketdyne despite a recent testing setback.
Air Force leaders didn't definitively say if they'll cut off funding, but said they're more interested in launch services than engines.
The company completed a series of hot-fire tests on the preburner design for the AR1, keeping the program on schedule to be flight-ready by 2019.
Aerojet Rocketdyne announced a second phase of the company’s consolidation plan April 10 that includes moving development of rocket engines from a decades-old California facility.
Aerojet Rocketdyne’s Julie Van Kleeck pitched the AR1 rocket engine to a roomful of reporters Tuesday morning as the only direct replacement for the reliable but politically polarizing Russian engine that powers the Atlas 5 rocket.
Aerojet Rocketdyne said Dec. 17 that the AR1 engine it hopes to build for United Launch Alliance’s next-generation rocket has completed a key design review.
Development of Aerojet Rocketdyne’s new engine could be delayed without sufficient government funding, company executives said here Sept. 15.
