The GE Haliade X, smaller but not by a lot, maxes out at 7 rotations per minute, giving a rotor tip velocity in the vicinity of 80m/s. Generally noise considerations mean you don't aim for a tip velocity faster than that, although for a turbine that is only installed in offshore or other uninhabited locations, you might design for a higher tip velocity. Despite some advantages to higher velocity, though, considerations related to erosion caused by high speed impact of dust, water drops and ice particles become an issue long before you'd get to supersonic speeds.
- antisthenes 3y ago> The GE Haliade X, smaller but not by a lot, maxes out at 7 rotations per second I think you meant per minute. Per second would mean that the rotor tips are travelling faster than SR-71.
- mcronce 3y agoAlthough I'm glad it's not reality, the imagery of a massive wind turbine whizzing around at 420 RPM is pretty amusing

- jacquesm 3y agoHehe, just to let you know your effort wasn't in vain, I got that.
- walnutclosefarm 3y agoYes. Thanks.
