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:

    Telephone poles were matchsticks, put there to be snapped off at a whim. Dogs trotting across the road were suddenly big trucks. Old ladies turned into moving—vans. Everything was too bright, but very funny and made for my delight. And about half a mile from my long liquid breakfast I turned carefully down a side street and parked, and sat beaming happily through the tannic fog for about an hour, remembering how witty we all had been, how handsome and talented ...
