- 出版タイプ： NA小型超音速伝熱風洞に混合圧縮型インテークのスロート部を模擬したキャビティ付超音速圧縮内部流路模型を取り付け、シュリーレン法による流れの可視化と圧力計測によってキャビティ抽気流量およびキャビティ形状が流れ場の構造および空力特性に与える影響について調べた。キャビティ抽気は混合圧縮型超音速インテークの始動特性を改善するが、過剰な抽気は圧力回復率の低下を引き起こすことが明らかとなった。また、キャビティ形状はキャビティ抽気とキャビティ圧力の関係に大きな影響を及ぼし、その結果、最大圧力回復率となる抽気流量や始動を確保するに必要な抽気流量はキャビティ形態に強く依存することが判明した。This paper presents experimental results of the effects of cavity bleed and its configuration on the supersonic internal flow field and the aerodynamic characteristics. The experiments were conducted in the supersonic heat transfer test facility of NAL (National Aerospace Laboratory) using the partial model to simulate the supersonic internal compression passage of the mixed compression air-intake. The pressure recovery characteristics of five cavity configurations was obtained for the bleed mass flow rates. It was found that the cavity bleed was effective for the starting of the air-intake but the excessive cavity bleed aggravated the pressure recovery. The cavity configuration affected the characteristics of the pressure in the cavity bleed plenum for the bleed mass flow rates. Therefore, the optimum bleed mass flow rates for the maximum pressure recovery depended on the cavity configuration.資料番号: AA0004254000レポート番号: NAL TR-1247
