 note = {老朽化対策と気流特性の改善を目的として、JAXA吹出式1m×1m超音速風洞の改修を実施した。改修後の気流変動を確認するため、主要マッハ数M(sub ∞)=1.4から4.0について、測定部の中心部および壁面でそれぞれ総圧(ピトー圧: P(sub 02))変動と静圧(P(sub w))変動について調べた。その結果、総圧変動については、改修前に比べて約1/2から1/6に減少したことが分かった。静圧変動(Cp (アンダーバー)rms: ΔPrms/q(sub ∞))については、0.1％＜Cp (アンダーバー)rms＜0.5％で、マッハ数が小さい方が大きいことが分かった。また、マッハ数M(sub ∞)=2.0の静圧変動を、乱れが小さい真空吸込型高速風洞と比較した結果、Cp (アンダーバー)rmsは1桁近く大きいことが分かった。(ただし、(アンダーバー)部分を記号のアンダーバーに変更して下さい。), After the upstream part of the JAXA blow-down 1 m x 1 m supersonic wind tunnel was modified to improve its flow qualities, the pressure fluctuations were measured in the test section at Mach numbers from 1.4 to 4.0. The rms values of the total (pitot) pressure fluctuations measured at the center of a cross section were reduced significantly, to about 1/2-1/6 of their former level. The ratio of the rms values of the static pressure fluctuations measured at the test section wall to dynamic pressure values decreased from about 0.5 percent to 0.1 percent with increasing tunnel Mach number. However, the level of the static pressure fluctuations at Mach 2.0 was one order of magnitude larger than that of a high-speed in-draft wind tunnel, which is reputed to be a quiet tunnel., 資料番号: AA0063584000, レポート番号: JAXA-RM-06-013},
