<p>The turbine has screw blades provided parallel to a rotor axis. The turbine is adapted as a two stage part in a pipe with different cross-sections such that characteristics of the turbine are defined according to a Bernoulli law. An output is obtained from correlation between flow speeds of two stages. A torque of rotors increases the flow speeds of the stages. A value of more than 2/3 of wind power of a working field is used as kinetic energy in one of the stages. The torque of the rotors is produced by a difference of static pressures of countersides of the screw blades.</p> |
