Abstract: The aeroelastic measurements on the oscillating NACA0015 profile vibrating as the dynamic system with two degrees of freedom (pitch and plunge) were realized within the interval of Mach numbers M = 0.08 to 0.45 and Reynolds numbers Re = (1 – 5) 105 in the wind tunnel of the Institute of Thermomechanics of the CAS. Frequency and amplitude characteristics of the vibrating profile and values of elastic strain energy corresponding maximum pitch and plunge displacements of the studied profile were detected.
