Description
Summary:The article is devoted to the quantitative assessment of the effectiveness of rotary screws. Presented by the further development of the method of calculating the aerodynamic characteristics of the rotary screw terminal for accounting losses and inductive reactance. The results of studies of the influence of geometric parameters of rotary screw on its cost-effectiveness. A method for improving the economic efficiency of the aircraft with rotary screw in the range of small and medium speeds forward flight by  setting the limit of the aerodynamic surfaces on the blades.
