N1 Block A

Subtopics

• Superraket Block A LOx/Kerosene propellant rocket stage. Ancestor of N1 Block A; conical liquid oxygen/kerosene stage using massive cluster of Kuznetsov engines. Gross mass estimated based on 2,000 metric ton total vehicle weight; empty mass estimated.
• 
  N1 1962 - A LOx/Kerosene propellant rocket stage. Earlier design for the Block A. Includes 14,000 kg for Stage 1-2 interstage and payload fairing. Compared to total fuelled mass excludes 15,000 kg propellant expended in thrust build-up and boil-off prior to liftoff. Values as in draft project as defended on 2-16 July 1962.
• 
  N1 1964 - A LOx/Kerosene propellant rocket stage. First stage of the N1 superbooster. As per draft project for N1-L3, 1964. Block A modified with six additional engines and propellant increased by 550 metric tons by using chilled propellants.
• N1F 1965 - A LOx/Kerosene propellant rocket stage. As per N1 improvement study, 1965. Block A engine thrust increased but little additional propellant.
• N1M 1965 - A LOx/Kerosene propellant rocket stage. As per N1 improvement study, 1965. Huge modification of Block A, almost double propellant capacity, engines increased from 175 metric tons thrust to 250 metric tons.
• N1U 1965 - A LOx/Kerosene propellant rocket stage. As per N1 improvement study, 1965. Primarily improved reliability and produceability compared to first model.
• N1F Block A LOx/Kerosene propellant rocket stage. Includes 14,000 kg for Stage 1-2 interstage.
• N1-MOK stage Air/LOx/LH2 propellant rocket stage. Ultimate derivative of N1 Block A: Propellants changed to LH2/LOX, 16 x modified NK-33 engines + 4 Liquid Air Cycle Engine Liquid Air/LH2 boosters. All figures estimated based on tank volume of Block A and delivery of 90,000 kg payload to 400 kg MKBS orb
