At the end of the main rotor shaft was installed at the top of the current collector devices for the power plant.

The first development in the USSR jet helicopter. Designers in the course of work are faced with technical difficulties, insurmountable at that time (in the turbojet engine and the load on the main rotor). The project is closed. 1-1962 First flight year.
