| Abstract: | Results of the experimental investigation of the self-excited torsional oscillation of an NACA 0006 airfoil suspended elastically are covered. The relationship between torsional oscillation and shedding of vortices was investigated for this airfoil. Two types of oscillation phenomena were found in the investigation. One type, exhibited by cases with angles of attack just above stall, persisted with increasing velocity without reaching any apparent limit within the range of velocity attainable in the present wind tunnel. The other type, exhibited by cases with higher angles of attack, only showed self-excited oscillations in a certain range of velocity range decreasing with increasing angle of attack. |
