The results of experimental researches of influencing of placing of the engine nacelles on aerodynamic descriptions of model of aircraft are showed. Researches are conducted in the wind-channel T-1 of Kharkov university of Air Forces. The chosen method of researches – gravimetric experiment. It is shown, that the location of engine nacelles on the lateral edges of wing promotes aerodynamic quality of aircraft in general. The increase of aerodynamic quality is conditioned by reduction of influencing of overflowing at the end of the over brim wing of the small lengthening in case of presence of the engine nacelle.
