Propellant - Propellant Used For Propulsion - Liquid Propellant

Liquid Propellant

Common propellant combinations used for liquid propellant rockets include:

  • Red fuming nitric acid (RFNA) and kerosene or RP-1
  • RFNA and Unsymmetrical dimethylhydrazine (UDMH)
  • Dinitrogen tetroxide and UDMH, MMH, and/or hydrazine
  • Liquid oxygen and kerosene or RP-1
  • Liquid oxygen and liquid hydrogen
  • Liquid oxygen and ethanol
  • Hydrogen peroxide and alcohol or RP-1
  • Chlorine pentafluoride and hydrazine

Common monopropellant used for liquid rocket engines include:

  • Hydrogen peroxide
  • Hydrazine
  • Red fuming nitric acid (RFNA)

In rockets, three main liquid bi propellant combinations are used

  • cryogenic hydrogen oxygen combination system - Used in upper stages and sometimes in booster stages of space launch systems.This is a nontoxic combination. This gives high specific impulse and is ideal for high velocity missions
  • liquid oxygen hydrocarbon propellant system - Used for booster stages of space launch vehicles. It has high density and hence allows for a more compact booster design
  • storable propellant combinations - used in large rocket engines for first and second stages of ballistic missiles and in almost all bi propellant low-thrust, auxiliary or reaction control rocket engines. They are instant starting and suitable for long-term storage

Famous quotes containing the word liquid:

    “While the State becomes inflated and hypertrophied in order to obtain a firm enough grip upon individuals, but without succeeding, the latter, without mutual relationships, tumble over one another like so many liquid molecules, encountering no central energy to retain, fix and organize them.”
    —Emile Durkheim (1858–1917)
