Doesn the wind shadow from one rotor inhibit the next rotor from getting wind?
That’s definitely a factor to consider. Our driveshaft is at an angle from horizontal, with the nose pointing slightly downward so that, with proper spacing, each rotor gets its own wind. In addition, the forward tilt of the rotors tends to direct the wind downward, pulling more fresh wind through the machine from above… Any slight losses of power from wind shadow effects are more than made up for by the overwhelming combined power of a multiplicity of rotors.
