  • Nitrous oxide/Amines 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. Early storable rocket systems sought to improve ignition characteristics and perforamance by eliminating the kerosene portion of the fuel. An amine is an organic compound produced when one or more hydrogen atoms of ammonia is replaced with organic groups. Mixed amine fuels were first developed by the Germans in World War II. TONKA-250, developed for the Wasserfall rocket, was used by the Russians after the war in various engines under the specification TG-02. More...
