At high Mach numbers, it is necessary to control suction rate of the test section by the suction blower in accordance with nozzle Mach number at the test section as well as rotation speed of the main blower. These three control systems were replaced or modified for one-man automatic operation at the re-test conditions if it is once started. Then, the operation points of the suction blower were discussed since they are widely spread according to the Mach number and the test model. The automatic procedures for changing these operation points and modification of the Mach number control were proposed. The choking area of the suction blower were also investigated, and the results of the automatic operation are shown. After the replacement, better productivity and accuracy of the data in the whole range of Mach numbers were achieved., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1830014000, レポート番号: JAXA-RM-18-005}, title = {JAXA 2m×2m連続式遷音速風洞の測定部抽気時の自動運転}, year = {2019} }
