 note = {低密度風洞で,吊下げ法による球の抵抗測定から,抵抗係数を既知として,気流の動圧決定を試みた.実験条件は気流マッハ数2,0～3.5,長さ1cmに対するレイノルズ数50～250である.同じ吊下げ法で,頭部が円形および正方形状の非常に軽い発泡スチロール製模型の抵抗係数を求め,レイノルズ数による変化ならびに形状による相異を示した., An attempt has been made of the determination of dynamic pressure in the low density wind tunnel by measuring the drag force exerted on a sphere with the wire suspension system and using the drag coefficient of sphere given by the empirical formula. The flow conditions of the present tests are in the Mach number range of 2.0～3.5 and in the Reynolds number range of 50～250 for the length of 1cm. With the same system, the drag forces experienced by ultralightweight models of foamed plastics with circular and square-flat noses have been measured. The effects of the Reynolds number and the shape of model on the drag coefficient have been examined., 資料番号: SA0125428000},
