摘要
The turbine has several parallel shafts (20) having two helical screw blades (3, 4) running along it. The blades are at an angle of 45 deg. and the two blades on a shaft are displaced from each other by half a turn of the helix. The turbine is positioned so that the shafts are at an angle of 45 deg. to the wind (5). This brings one half of each blade perpendicular to the wind and the other half parallel to it.
