Dear @Melancho7ee, Teeter is unique feature of some two-bladed rotors where a rotational joint (teeter pin) is added between the shaft and hub to prevent non-torque bending loads from transferring to the shaft from the rotor. See Figures 14 and 15 and accompanying text from the old FAST v6 User's Guide for more information: https://openfast.readthedocs.io/en/main/_downloads/d8bd014121d6505cb25cf49bee5eaa80/Old_FAST6_UsersGuide.pdf. Best regards, |

Since I am not an English native speaker, I failed to capture the real meaning of the teeter motion of a 2-bladed wind turbine. Could anyone help me to understand this definition? Many thanks if pictures or GIFs provided.
