APPLICATION OF THE PRINCIPLE OF FAVORABLE INTERFERENCE TO INCREASE THE AERODYNAMIC PERFORMANCE OF THE PROPELLER AND WING CONFIGURATION
SINOPSIS
Within the framework of a model of an ideal incompressible fluid, the interaction between a wing and a propeller installed on the tip of the wing is investigated. The spanwise circulation distribution of the wing with propellers for minimum induced drag was obtained. An assessment is given of the lift-to-drag ratio increment due to induced drag reduction under the action of a propeller swirl jet. A comparison of the numerical results with the experimental investigations in a wind tunnel for an aircraft model with the wing tips mounted on the electrical engines with two-blade propellers is presented. The experimental results confirmed the theoretical assumptions in relation to the possibility of using the flow twisting behind tractor single-row propellers to induce drag reduction of the wing and increase the lift-to-drag ratio by 10%.
