  2. Hypergolic propellant - Wikipedia

    en.wikipedia.org/wiki/Hypergolic_propellant

    A hypergolic propellant is a rocket propellant combination used in a rocket engine, whose components spontaneously ignite when they come into contact with each other. The two propellant components usually consist of a fuel and an oxidizer .

  3. Devil's venom - Wikipedia

    en.wikipedia.org/wiki/Devil's_venom

    Devil's venom was a nickname coined by Soviet rocket scientists for a hypergolic liquid rocket fuel composed of a dangerous combination of red fuming nitric acid (RFNA) and unsymmetrical dimethylhydrazine (UDMH). [1]

    Leaks could mean the risk of explosion, because the fuel inside the Dragon’s Draco engine is made of hypergolic propellant. Hypergolic fuels, like hydrazine, are toxic liquids that react ...

  5. Monomethylhydrazine - Wikipedia

    en.wikipedia.org/wiki/Monomethylhydrazine

    Monomethylhydrazine (MMH) is a highly toxic, volatile hydrazine derivative with the chemical formula CH 6 N 2.It is used as a rocket propellant in bipropellant rocket engines because it is hypergolic with various oxidizers such as nitrogen tetroxide (N 2 O 4) and nitric acid (HNO 3).

  6. 2-Dimethylaminoethylazide - Wikipedia

    en.wikipedia.org/wiki/2-Dimethylaminoethylazide

    2-Dimethylaminoethylazide (DMAZ) is a liquid rocket fuel being investigated for use as a spacecraft propellent to replace the toxic, carcinogenic monomethylhydrazine. [1] It is a member of the competitive impulse non-carcinogenic hypergol (CINCH) family which were assessed as a replacement for hydrazine-derived propellants.

  7. Liquid apogee engine - Wikipedia

    en.wikipedia.org/wiki/Liquid_Apogee_Engine

    Apogee engines typically use one fuel and one oxidizer. This propellant is usually, but not restricted to, [7] a hypergolic combination such as: N 2 H 4 / N 2 O 4, MMH/ N 2 O 4, UDMH/ N 2 O 4. Hypergolic propellant combinations ignite upon contact within the engine combustion chamber and offer very high ignition reliability, as well as the ...

  8. Aerozine 50 - Wikipedia

    en.wikipedia.org/wiki/Aerozine_50

    Aerozine is not used as a monopropellant (a propellant that is not mixed with anything). The extra stability conferred by the methyl groups affects reactivity and thrust. In 1980, an accidental leakage of Aerozine 50 resulted in the 1980 Damascus Titan missile explosion. The leak occurred due to puncture of the first-stage Titan fuel tank by a ...
