Nitrous oxide/Alcohol propellant. Nitrous oxide has advantages as a rocket engine oxidizer in that it is non-toxic, stable at room temperature, easy to store and relatively safe to carry on a flight. Its disadvantage is that it must be stored as a gas, which make it more bulky than liquid oxidizers. Alcohol (C2H5OH) was the fuel used for the German V-2 rocket, and the first derivative rocket engines in the United States, Soviet Union, and China. After better-performance rocket-grade kerosene was developed by Rocketdyne in the REAP program of 1953, use of alcohol was abandoned. Interest was renewed in the 21st Century as part of this non-toxic, storable propellant combination.
