These transducers were especially designed to be easily and directly applied to any arbitrary spot on the moving surface. Measurements are carried out while changing Reynolds number, angle of attack, and frequency of airfoil oscillation. Analysis of these measurements indicates that the characteristics of the pressure distribution depend essentially on whether or not the airfoil is operating in the stalled state. Furthemore, the normal forces calculated from the pressure distributions are found to be in good agreement with those measured directly by means of a strain gauge., 資料番号: SA0125204000}, pages = {323--341}, title = {並進振動する楕円翼面上の変動圧力の測定}, volume = {9}, year = {1973} }
