MULTI-TURBINE AIRFLOW AMPLIFYING GENERATOR

摘要

A wind generating device employs modules each having two turbines. Each turbine employs two rotors coaxially aligned by a shaft associated with an in-line generator. Alternatively, the turbine employs only one rotor for low-wind areas. The arrangement includes a proximal channel with a leading portion having decreasing radius toward the first rotor which acts as a collector and a following portion connecting fluidly the first and second rotor and a distal channel which is separate from the proximal channel and opens into the following portion, adding to the airflow to the second rotor. Downstream from the second rotor is a diffuser with a radius increasing with distance from the rotor. Surrounding the second rotor is a boundary layer control collar creating channels associated with one or more channels between diffuser segments. The modules may be stacked vertically allowing for yaw responsive to wind and may be mounted on a tower.
