Why is the RD-180 so good?
Why Is Rd-180 So Good? It is designed to use fuel as light as kerosene through its highly pressurized stage combustion cycle and oxygen saturation of the fuel. These characteristics give it a very particular impulse in terms of low fuel consumption (low fuel consumption).
