Associated Launch Vehicles
  • N1F Russian heavy-lift orbital launch vehicle. The N1F would have been the definitive flight version of the N1, incorporating all changes resulting from the four flight tests of the vehicle, including the new Kuznetsov engines and 10% greater liftoff mass by using superchilled propellants in all stages. N1 8L would have been the first N1F configuration flight, with launch planned in the third quarter of 1975 at the time the project was cancelled. More...

Associated Propellants
  • GOX/Kerosene Gaseous oxygen is used as an oxidiser in Russian thrusters for orbital maneuvering and orientation. It is a by-product of liquid oxygen, used in the main engine, and slowly boiling off over time. Rocket propellant RP-1, or its foreign equivalents, is a straight-run kerosene fraction, which is subjected to further treatment, i.e., acid washing, sulphur dioxide extraction. Thus, unsaturated substances which polymerise in storage are removed, as are sulphur-containing hydrocarbons. More...
