Wind Turbine. Windmills make flour

Simple really...windmilling is experienced when the RPM is reduced but the airspeed is maintained,which eventually will cause the blade angle of attack to become negative,when that occurs,the resulting force will act in a rearward direction,known as windmilling.We use it in jets as well,windmilling starts occurs,when the engine is started without the aid of the starter,because the compressors are being turned by natural airflow when airborne.To,which I have done several,when the buggars have decided to quit.

Would be interested to find out if those same aerodynamic features are the same for windmills,as they really are only just big props,as in constant speed props,or constant speed unit.
