Why not just feather the blades to a higher pitch to deal with excess wind speed instead of just on/off?,(reply>), @Arnav Dhamija  It's been 7 years but that sounds like a cool concept.,(reply>), I understand. IIRC this was an idea for using a ramjet + turbofan on supersonic aircraft. The turbofans would feather at Mach 1.00+ speeds to prevent damage and let the ramjets take care of power from there on.<br><br>But feathering the blades isn't better than locking the blades IMO as the blades aren't going to produce power in either configuration. It might be safer for the blades though.,(reply>)," It leans rotating the blades on the long axis to adjust the pitch to control speed. <a href=""http://en.wikipedia.org/wiki/Blade_pitch#Feathering"">http://en.wikipedia.org/wiki/Blade_pitch#Feathering</a>",(reply>), What do you mean by "feather the blades"?
