Transcription

Versions

The basic engine has been used since the Feng Bao 1 rocket and has been the vernier propulsion of the Long March 2, Long March 3 and Long March 4 families second stage.[1][9][10]

  • YF-23: Original version.
  • YF-23B (AKA DaFY21-1): Improved version.[9][11][12]
  • YF-23F: Improved version.[9]

Modules

This engine is bundled into modules along the YF-22 upper stage engine.[13][14][15][16]

The relevant modules for second stage application are:

  • YF-24: A module comprising an YF-22 and a single YF-23 verniers.
  • YF-24B: A module comprising an YF-22B and a single YF-23B verniers.
  • YF-24E: A module comprising an YF-22E and a single YF-23F verniers.[17]
