| Abstract: | | 1. |
The results of the first full-scale experiments with orthogonal wind turbine generator units showed their performance, the possibility of creating on their basis large units of a simple design intended mainly for use in power systems.
| | 2. |
The maximum wind power coefficient of the rotorC
n somewhat exceeds the calculated values, reaching values of 0.50–0.56 at blade speeds equal to about three wind speeds.
| | 3. |
The aerodynamic drag coefficients of structural elements of type VL-2 rotors with guys can reach  a=0.06–0.07, which substantially exceeds the profile drag of the operating blades. Elimination of the guys and a relative increase of the area of the working blades in type VL-2N rotors makes it possible to reduce the indicated drag coefficient to a=0.031–0.033.
| | 4. |
At wind speeds exceeding 0.5–0.6 the blade speed and power output of the unit cease to depend on the wind speed. This property of orthogonal units protects the generator from overloads, simplifies regulation, and increases the reliability of the plants.
