    Abstract
  • The secondary flow vector control concept for the fluidic throat nozzle of solid rocket motor was studied. Through numerical simulation, the work condition of concurrent thrust modulation and vector control was analyzed, in which there exist secondary flow at the throat and expansion part meanwhile. The throat modulation and thrust vector control performance of nine typical secondary flow concepts were compared, and the influence on the secondary flow vector control was discussed for the existence of secondary flow at the throat. The results of concept comparison can provide references for practical design.
