Краткое описание

This paper considers the influence of a periodic non-uniformity of a flow incoming on a wing with a value of average velocity at which instability of natural wing vibrations can appear. A theoretical evaluation of this influence is given for small flow non-uniformity. This evaluation is given at the condition of a parametric resonance appearance for a ratio of natural wing vibrations and frequencies of exciting forces, the appearance of which is determined by the flow non-uniformity. The appropriate experimental investigations, the results of which qualitatively agreed with the theoretical results, were carried out.
