RD-0107

The RD-0107 was a Soviet rocket engine designed in the 1950s for space and missile applications. It used liquid oxygen and kerosene as propellants, and operated with a staged combustion cycle, meaning it efficiently used its propellants to generate high thrust. This engine was notable for its reliability and performance during early Soviet space efforts. It was primarily used in the R-7 rocket family, which launched Sputnik, the first artificial satellite. Overall, the RD-0107 played a key role in advancing Soviet space technology and capabilities during the early space race era.
