Annotations languages:

In the article aerodynamic configuration of the air screw with the arch-ring wing, intended for planes using small speeds of flight for a long time is presented. The complex semiempirical method of definition of aerodynamic characteristics of difficult spatial configurations that is caused by difficulties of carrying out of weight experiment with air screws in a wind tunnel is developed. Dependences of coefficient of aerodynamic elevating force of an arch-ring wing on loading factor on a sweeped surface of the air screw are received.
Keywords: aerodynamic configuration, an arch-ring wing, the air screw, aerodynamic characteristics, a complex method
