pages 1525 - 1533, full text

The two-dimensional flow pattern around the vibrating profile NACA0015 with his selfexcitation mode was measured in the wind tunnel by optical methods. The used profile with two-degreeof-freedom moved in the vertical direction to the flow direction and rotated around the elastic axis in 1/3 of the profile chord. The M ach numbers for the self-excitated profile vibrations was in the interval 0.20.45. Some results of the interferometric measurements and the profile kinematic movements during the self-excitations are presented.
