| مستخلص: | Buffet characteristics of the BGK No. 1 shockless airfoil have been investigated. Fluctuating pressure measurements along the airfoil chord and unsteady force balance data have been obtained in various regions inside the buffet regime close to the onset boundary curve. The Mach number range where buffet intensity reaches high values is determined from balance measurements. The rms values of the fluctuating pressure show generally monotonic increase downstream of the shock to the trailing-edge in this speed range. Statistical data from pressure and normal force measurements have been processed and the appearance of distinct frequency peaks in the power spectral density curves has been detected. in French. |
