Basic results got during the works implementation period: formation of the longitudinal vertical flow around the wing is perspective method of flow separation management; as a result of transversal and large longitudinal whirlwinds (LLW) co-operation dynamics analysis was shown that the disturbances from nose LLW vortex generators results in the loss of transversal whirlwinds stability; by experimental and calculation methods was determined that the application of LLW vortex generators gives relatively to AC characteristics the increase of ?dop by 10-15%; a scientifically-methodical complex was developed, that provides estimation of influence authenticity of different vortex generators schemes on aerodynamic characteristics of body.
