    en.wikipedia.org/wiki/Bulk_loaded_liquid_propellants

    In the 1950s through 1970s, a mixture of 63% hydrazine, 32% hydrazine nitrate and 5% water was used in experimental 37mm gun firings and later in 120mm gun firings. The 32% hydrazine nitrate mixture was selected by extensive experiments to have a notably flat pressure profile, increasing gun safety.

  3. Hydrazine - Wikipedia

    en.wikipedia.org/wiki/Hydrazine

    Since hydrazine is a solid below 2 °C, it is not suitable as a general purpose rocket propellant for military applications. Other variants of hydrazine that are used as rocket fuel are monomethylhydrazine , CH 3 NHNH 2 , also known as MMH (melting point −52 °C), and unsymmetrical dimethylhydrazine , (CH 3 ) 2 NNH 2 , also known as UDMH ...

    Feedwater system piping: ferrus or mixed metallurgy (e.g. copper feedwater train) all-ferrous metallurgy: all-ferrous metallurgy: all-ferrous metallurgy Dissolved oxygen level < 10 ppb: 1 to 10 ppb: 30-50 ppb (drum), 30-150 (supercritical) 30-50 ppb (drum), 30-150 (supercritical) Chemicals added: a reducing agent (such as hydrazine), ammonia to ...

  5. Aerozine 50 - Wikipedia

    en.wikipedia.org/wiki/Aerozine_50

    Aerozine continues in wide use as a rocket fuel, typically with dinitrogen tetroxide (N 2 O 4) as the oxidizer, with which it is hypergolic. Aerozine 50 is more stable than hydrazine alone, and has a higher density and boiling point than UDMH alone. Pure hydrazine has a higher performance than Aerozine 50, but an inconvenient freezing point of ...

  6. Monopropellant - Wikipedia

    en.wikipedia.org/wiki/Monopropellant

    The most common use of monopropellants [3] is in low-impulse monopropellant rocket motors, [4] such as reaction control thrusters, the usual propellant being hydrazine [5] [6] which is generally decomposed by exposure to an iridium [7] [8] catalyst bed (the hydrazine is pre-heated to keep the reactant liquid).

  7. Unsymmetrical dimethylhydrazine - Wikipedia

    en.wikipedia.org/.../Unsymmetrical_dimethylhydrazine

    UDMH is a derivative of hydrazine and is sometimes referred to as a hydrazine. As a fuel, it is described in specification MIL-PRF-25604 in the United States. [13] UDMH is stable and can be kept loaded in rocket fuel systems for long periods, which makes it appealing for use in many liquid rocket engines, despite its cost.

  8. Operation Burnt Frost - Wikipedia

    en.wikipedia.org/wiki/Operation_Burnt_Frost

    Operation Burnt Frost was a military operation to intercept and destroy non-functioning U.S. National Reconnaissance Office (NRO) satellite USA-193. [1] The mission was described by the Missile Defense Agency as a "mission of safeguarding human life against the uncontrolled re-entry of a 5,000-pound satellite containing over 1,000 pounds of hazardous hydrazine propellant". [2]

  9. Hypergolic propellant - Wikipedia

    en.wikipedia.org/wiki/Hypergolic_propellant

    The Komet had a HWK 109-509, a rocket motor which consumed methanol/hydrazine as fuel and high test peroxide T-Stoff as oxidizer. The hypergolic rocket motor had the advantage of fast climb and quick-hitting tactics at the cost of being very volatile and capable of exploding with any degree of inattention.
