STUDY OF THE SMALL FLUCTUATIONS OF THE BODY TOCOMPLEX DESCSIDE IN FLOW OF THE AMBIENCE
Abstract
The work is devoted to the construction and investigation of a mathematical model of a body of a complex configuration that performs auto-oscillations in the flow of a quasi-static medium under the action of aerodynamic forces. A violation of uniqueness is determined in determining the angle of attack in certain positions of the body. The dependence of the angle of attack on the phase variables for a particular plate is plotted and the boundary of the ambiguity region is indicated. It is indicated that in determining the angle of attack, one must proceed from its continuity. The stability of the state of rest is investigated. It is shown that the aerodynamic forces are of an accelerating nature and, as a result of interaction with the medium, the body under consideration can perform oscillations with a growing amplitude in the medium flow. Proposed programs that allow carrying out numerical studies in order to confirm the regimes found and evaluate the adequacy of the proposed model.
