DISTRIBUTION OF UNSTEADY WING PRESSURE WITH VORTEX GENERATORS

O.G. Shcherbonos

Paper is devoted to the study of unsteady aerodynamic characteristics of wing with vortex generators. A description of the experimental setup, the experimental parameters and results of investigating the distribution of the instantaneous pressure coefficients on the wing vortex generators in conditions of unsteady flow. Shown to increase the amplitude of the peak rarefaction swing-wing vortex generators in comparison with smooth control wing, which indicates a greater manifestation of the effects of unsteady aerodynamic, and more dynamic hysteresis of aerodynamic coefficients, which appears in the oscillations of the wing.

Key words: a wind tunnel, non-steady aerodynamics, vortex generators.
