摘要

Rocket-engine developments that evolved from preparations for an advanced strap-on booster to lift the largest version of the planned Space Launch System (SLS) could push a prototype 500,000-lb.-thrust U.S. replacement for Russia's RD-180 to the test stand in 2.5 years, contractors say. Dynetics and Aerojet Rocketdyne (AJR) have joined forces on risk-reduction work growing out of NASA's SLS advanced booster program and the Air Force Research Laboratory (AFRL) Hydrocarbon Boost effort. The goal is to hasten the AR-1 hydrocarbon-fueled rocket engine being proposed by AJR in hopes that Congress and the Pentagon will decide to go all-out on a U.S. powerplant for national security space launch in place of the RD-180.
