  4. Liquid-propellant rocket - Wikipedia

    en.wikipedia.org/wiki/Liquid-propellant_rocket

    One of the most efficient mixtures, oxygen and hydrogen, suffers from the extremely low temperatures required for storing liquid hydrogen (around 20 K or −253.2 °C or −423.7 °F) and very low fuel density (70 kg/m 3 or 4.4 lb/cu ft, compared to RP-1 at 820 kg/m 3 or 51 lb/cu ft), necessitating large tanks that must also be lightweight and ...

    Dinitrogen tetroxide (N 2 O 4) and hydrazine (N 2 H 4), MMH, or UDMH. Used in military, orbital, and deep space rockets because both liquids are storable for long periods at reasonable temperatures and pressures. N 2 O 4 /UDMH is the main fuel for the Proton rocket, older Long March rockets (LM 1-4), PSLV, Fregat, and Briz-M upper stages.

  6. RP-1 - Wikipedia

    en.wikipedia.org/wiki/RP-1

    Russia is also working to switch the Soyuz-2 from RP-1 to "naftil" [10] or "naphthyl". [11] [12] After the RP-1 standard, RP-2 was developed. The primary difference is an even lower sulfur content. However, as most users accept RP-1, there was little incentive to produce and stock a second, even rarer and more expensive formulation.

    Kestrel was a LOX/RP-1 pressure-fed rocket engine, and was developed by SpaceX as the Falcon 1 rocket's second stage main engine; it was used in 2006–2009. It was built around the same pintle architecture as SpaceX's Merlin engine but does not have a turbo-pump , and is fed only by tank pressure .

    en.wikipedia.org/wiki/SpaceX_Merlin

    In October 2012, SpaceX publicly announced concept work on a rocket engine that would be "several times as powerful as the Merlin 1 series of engines, and won't use Merlin's RP-1 fuel". [58] They indicated that the large engine was intended for a new SpaceX rocket, using multiple of these large engines could notionally launch payload masses of ...

  9. Archimedes (rocket engine) - Wikipedia

    en.wikipedia.org/wiki/Archimedes_(rocket_engine)

    Archimedes is presented as a highly reusable liquid-propellant engine using methane and liquid oxygen in an oxidizer-rich staged combustion cycle. [1] [2] There are both sea-level and vacuum variants. The engine is mostly 3D printed, [7] with some of the biggest 3D printers in the world. The rationale for the cycle change from the original gas ...
