The RD-180 (Russian: Ракетный Двигатель-180 (РД-180), romanized: Raketnyy Dvigatel-180, lit. 'Rocket Engine-180') is a rocket engine that was designed and built in Russia. It features a dual combustion chamber, dual- nozzle design and is fueled by a RP-1 / LOX mixture.

2024年1月11日 · Arguably, one decision made in the mid-1990s led directly to the Vulcan: the decision to use a Russian-made rocket engine, called the RD-180, as the primary engine for the Atlas III and, later...

2024年7月30日 · The dual-nozzle RD-180, made by a Russian company named NPO Energomash, consumes kerosene and liquid oxygen propellants and generates 860,000 pounds of thrust at full throttle.

2024年8月26日 · The RD-180 rocket engine has had a remarkable journey from its origins in the Soviet space program to its long career powering American rockets. Along the way, it has demonstrated impressive capabilities, supported groundbreaking missions, and sparked heated political debates.

The RD-180 was a two-thrust-chamber derivative of the four-chamber RD-170. It packaged the high performance, operability, and reusability features of the RD-170 in a size to meet the propulsion requirements for the Atlas V Evolved Expendable Launch Vehicle.

2019年6月26日 · The designs of both the BE-4 and SpaceX’s Raptor are informed in crucial ways by the RD-180. The BE-4 is an oxygen--rich staged-combustion engine, like the RD-170 and RD-180.

2023年6月7日 · The RD-180 rocket engine is a highly capable and reliable propulsion system that has been instrumental in powering the Atlas V launch vehicle. With its staged combustion cycle, high performance, and efficient propellant utilization, the RD-180 has proven itself in numerous successful missions.

The RD-180 is a LOx rich, closed cycle, staged combustion, LOx Kerosene engine, with throttle capability from 47% to 100% power level. The closed cycle engine with continuous throttling provides an unprecedented advantage to vehicle performance and mission profile flexibility, while still providing a very reliable engine design.

2021年7月8日 · The RD-180 is a two thrust chamber derivative of the RD-170 engine which powers the Zenit first stage. The RD-180 was developed in Russia and is marketed jointly by NPO Energomash and Pratt & Whitney.

The RD-180 engine has performed extremely well for some of America’s most sensitive national security satellites, such as those used for missile warning and protected communications.
