The results of the observation by a high-speed camera show that the state of the operation fluid flow is classified into three patterns. The time history of the thrust is observed oscillating change, and the frequency characteristics are analyzed by FFT and DWT. However, all the causes of oscillating behavior of the thrust are not elucidated. The transition time from liquid-phase flow to churn flow buried in the oscillating thrust is detected as a discontinuous point in the thrust curve by applying wavelet transform technique., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064672020, レポート番号: JAXA-SP-09-011},
