Isaev, E. Kalinin, A. Sudakov, V. Kharchenko] On the basis of multiblock computational technologies and the Menter model of shear-stress transfer modified with account of the curvature of streamlines, the optimum position of a slot for air suction on the leeward side of the contour of a vortex cell built in a thick NACA0022 airfoil was determined for the purpose of increasing its lift-drag ratio to a maximum value in a nondisturbed air flow at a Mach number of 0.05 and an angle of attack of 7°.
