EXPERIMENTAL AND THEORETICAL RESEARCHES ON INFLUENCE OF PARAMETRIC EXCITATION ON THE FLUTTER CRITICAL SPEED OF AIRCRAFT MODEL OF WING
RESUMO
In this paper it is pointed out that the margin of stability may have peculiarities in the case of flutter. By means of computing and experiment on a dynamically similar model of the wing in a wind tunnel the cantilever flutter was obtained. A reduction in the critical flutter speed was identified during periodic impact of vortex generator on the model wing with a frequency twice the frequency of flutter. Measurement of flutter parameters, self-oscillation, and external influences were performed by using certified measuring complex.
