Краткое описание

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.

Ключевые слова: parametric excitation, flutter, wind tunnel
