Yaw moment required to yaw wind turbine

Permalink Submitted by Anonymous on September 25, 2013

You are assuming that due to the gyro effect, it would require a large moment to 'yaw' the spinning turbine. Since there is no 'component' of the rate of change of angular momentum, when resolved around the yaw axis, the moment from the gyro effect is zero.
