Miyazaki Citizen's Plaza), Miyazaki, Japan, Flows in the rocket engine nozzles are numerically analyzed to assess the performance of Thrust Vector Control (TVC) system of fluidic type by the Direct Simulation Monte Carlo (DSMC) method. Secondary jet is injected into the flow field through a small tube attached to either side of two-dimensional dual throat nozzle wall. The main flow separation caused by the secondary jet is observed, and the direction of the thrust vector deviates from the symmetry axis of the nozzle. However, the deviation also occurs randomly when the secondary jet is stopped, which is not intended in the TVC system. In order to avoid it and perform the infallible deviation when intended, some research for the appropriate nozzle shape and the position of the secondary jet injection is done., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1830029014, レポート番号: JAXA-SP-18-005}, pages = {135--140}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {DSMC 法による流体式推力方向制御装置の性能解析}, volume = {JAXA-SP-18-005}, year = {2019} }
