I am working on the problem of variable pitch load of wind turbines. I would like to ask you some questions about the blade root load,
1.which parts of RootMzc1 are composed of? Is it the sum of aerodynamic torque, centrifugal torque and gravity torque, and does it include the friction torque of variable rotor bearing?
2.Is it convenient for you to provide the mathematical model of variable paddle load?
