    • There are similar issues with other even numbers of blades, including for our purposes a single-blade rotor, since it only has a counterweight on the other side and nothing to balance the unequal wind forces.

      There are similar issues with other even numbers of blades, including for our purposes a single-blade rotor, since it only has a counterweight on the other side and nothing to balance the unequal wind forces.

    • If the rotor has an odd number of blades, like three or five, the fact that blades don't come in pairs means that wind loads are more evenly distributed across the face of the rotor, and so the bending and twisting forces are greatly reduced.
