The analysis of expediency of replacement of regular tail beam is conducted with steering spirally of helicopter of МСБ- 2 on the circulation-stream system of the ground management and indemnification of reactive moment (NOTAR). Work of such system is provided by the supercharger set in root part of tail beam. The calculation of descriptions of the circulation system is conducted. The diameter of tail beam made a 0,75 m, width of crack are a 5,6 mm, length of crack are a 2,35 m. The parameters of single-stage supercharger, that provides the serve of air in a tail beam with a mass expense 7,63 kg/p. Calculations confirm that for the helicopter of type of МСБ- 2 providing of the ground balancing is possible the system of the circulation flowing around, are certain. Calculation power that will be required to work of such system is 138 kW.

Calculations confirm that for an easy helicopter, providing of the ground balancing is possible the system of the circulation flowing around. Power required to work of such system on the mode of hanging, in two times exceeds power being on a steering screw. The circulation flowing around provides indemnification of 60% of reactive moment here, expending 17% powers (rest of reactive moment is compensated by the stream system) only.

On the mode of level-flight the stream-circulation system consumes considerably less power due to the presence of keels. For reduction of the required power for balancing and management of helicopter on the mode of hanging it is necessary to redistribute the stakes of indemnification of reactive moment by the increase of stake of the circulation system to 85.90%, and also: to increase the diameter of tail beam; to increase length of crack; to apply two cracks; to displace one crack on a corner 20° downward from the plane of symmetry; to increase speed of blowing away stream; to increase length of tail beam
