To the issue of the exclusion of jog which formed between the fuselage and bonnet helicopter in the process of constructing a geometric model

Abstract

The complex of issues aimed at improving the quality of the developed aerodynamic model helicopters is discussed. Existing model of the helicopter is analyzed to identify deficiencies in the smoothness of curves, forming the aerodynamic contours. The method of improving the quality of the surface contours is proposed. Based on the proposed methodology it was developed several variants of the new contours with insignificant increase in cross-sectional area.
