Question:
A wind turbine rotor such as shown schematically in Figure 7.4 has a rotor rotation rate of Ω = 0.159s−1 (or a frequency of 1 Hz.), and is yawing at an angular rate of ω = 0.175s−1 (or a velocity of 10◦/s). The polar moment of inertia of the rotor is J = 13, 558 kg-m2. The rotor weighs 1,459 kg and is 3.05 m from the bearing support that holds the main rotor shaft.
1. What is the load on the bearing when the turbine is not yawing?
2. What is the load on the bearing when the turbine is yawing?
