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.
