Application of local boundary layer suction for laminarized profiles at low Reynolds numbers

The work is devoted to an experimental study of the drag of a high-carrying laminarized airfoil with a Reynolds number of 500,000 in the case of application of a wavy surface on a wing and a local suction of the boundary layer. The velocity profile was measured in the wake of wing models with a smoo...

Description
Summary:The work is devoted to an experimental study of the drag of a high-carrying laminarized airfoil with a Reynolds number of 500,000 in the case of application of a wavy surface on a wing and a local suction of the boundary layer. The velocity profile was measured in the wake of wing models with a smooth (classical) and wavy surface with a laminarized airfoil GU-25-5 (11)_8_mod. Airfoil drag was determined by the loss of momentum in the near wake adjusted by the Jones method.
