A good agreement is found between the results of the present experiment and those of the numerical calculation given in the previous paper. From the viewpoint of the viscous effects of flow, influences of Reynolds number, angle of attack and reduced frequency on these aerodynamic forces are discussed for the aerofoil which is in either non-stalled or stalled state. Experimental results are also compared with those of the potential flutter theory for a flat plate or a von Mises profile, those of the modified potential flutter theory proposed by Rott and George, and those predicted by the quasi-steady theory., 資料番号: SA0125461000}, pages = {1--35}, title = {並進振動する楕円翼まわりの非定常粘性流れ(その2実験)}, volume = {8}, year = {1972} }
