Numerical study of self-induced wing rock of a low-aspect-ratio delta wing in the presence of external disturbances
G. M. Shumsky Novosibirsk State Technical University, Novosibirsk, 630092, Russia
Abstract:
Self-induced wing rock of a delta wing, in particular, in the presence of external disturbances are studied by means of numerical simulations of a separated flow of an ideal incompressible fluid around a delta wing. The results obtained are compared with experimental data. The vortex nature and the mechanism of self-induced oscillations are studied. Regions of synchronization of the aerodynamic self-oscillatory system in the presence of external disturbances are identified. Methods of suppression of self-induced wing rock are proposed.
Keywords:
umerical study, delta wing, self-induced wing rock, external disturbances, capture of frequency, suppression of self-induced oscillations.
