Applied hydromechanics, Vol. 14 (86) ¹ 4, (2012) p.47-58
Results of experimental researches of influence of diffuser type vortex's generators on aerodynamic characteristics of plane model "Aeropract A-20" are resulted depending on their accommodation along a chord of a wing at a deviation of a flap on 10°. Experiments are executed in wind tunnel TAD-2. At not rejected and rejected flap the increase of elevating force coefficient is revealed at the maximal corners of attack. At the rejected flap the greatest effect is fixed at accommodation of vortex generators on distance of 20% of awing chord. In this case coefficients of resistance and the longitudinal moment practically did not change.
