Incorporation of RD-180 Failure Response Features in the Atlas V Booster Emergency Detection System Felix Y. Chelkis NPO Energomash Khimki, Moscow Region, Russia Thaddeus D. Chwiedor United Launch Alliance, Denver, Colorado, USA Paul T. Connolly and John P. Hansen Pratt Whitney Rocketdyne, Jupiter, Florida, USA Abstract Approximately 70% of the parts on the RD-180 engine as used on Atlas V launch vehicles are common with the RD-170 engine. The RD-170 engine was developed by NPO Energomash and certified in 1985 to power the Energia Buran rocket launch system, which was rated for human spaceflight as defined by the Russian standards. With over 45,000 seconds of operational time, the RD-180 has an extensive history of demonstrated performance, robustness, and reliability as does the Atlas vehicle that it powers. This paper describes why the RD-180/Atlas combination provides an optimal solution for human space flight directly applicable to the near-term commercial crew transportation program. The paper will examine how the RD-180/Atlas booster combination could meet Commercial Crew space flight requirements. An overview of the past NASA human space flight requirements to the Russian approach for manned flight will also be made. The paper will discuss the work that has been done to understand not only the potential failure modes to
