The Reynolds number, based on the airfoil chord, c, and the free stream velocity, U, is 8.6 x 10(exp 4). The airfoil underwent pitching up and pitching down motion between angle of attack of 0 to 30 degrees at a reduced pitch rate, Omega (equals to omega x c/(2U), where omega is pitch rate (rad/s)) of 0.012. The amount of the injection during one period is 47 percent of that of the constant injection and 78 percent of that of the proportional injection., 資料番号: AA0001655021, レポート番号: NAL SP-40}, pages = {81--82}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {動的失速の最適制御}, volume = {40}, year = {1999} }
