Some NACA0015 profile support variants with self-excited vibration in subsonic fluid flow

Popis výsledku v původním jazyce

One of the important domain of the contemporary aeroelasticity is the self-excited vibration of isolated profiles together with the self-excited vibration of profiles located in blade cascades. The Institute of Thermomechanics of the AS is engaged in group of projects concerning this aeroelastic problem. Results presented here were obtained solving a part of them [1-5].This experiments were realized in the wind tunnel of suction type placed in the laboratory of the Institute in Nový Knín. Profile NACA0015 with two degrees of freedom support was used. Profile was embedded with variable rotational and translational elasticity. The attention of this paper is concentrated on the time records and corresponding spectra of the translational and rotational movement during the self-excited vibration of the profile. Further results related to other parameters of this vibration will be published separately.
