Boeing 747 Fan blades

[dull spark]

HI every one, I see a set of fan blades for sale on ebay,they are off a Boeing 747 I was thinking would these be any good for a wind turbine,I was thinking they could be fitted inside a large alloy tube, pipe, etc,with a funnel type entrance to the fan blades,but as they were designed to be Jet engine driven, would they do the job,Pitch angle of blades maybe not suitable, any advice out there,
or am I still up in the clouds, Price £300 approx
Thanks all.

Look up a website named Windy nation. They are all about wind turbines and probably more in tune with all things wind turbines.

The stator compressor blades (fixed) would work efficiently as wind turbine blades, but not the rotor blades (opposite profile of what's needed for good efficiency).
The opposite is true for the exhaust side, where the rotor blades would be desirable - though completely overkill due to the alloy ( & hence price).

Hello, and thank you for the web address,have decided they are not suitable for wind turbine,the blades look real cool,sad to see high precision gear like this go to the breakers yard,
thanks again.

Thanks for the good advice,I am easily carried away, Just the look of those lovely big blades idling on the tarmac, I could imagine them on a 40 foot tower driving a big alternator, might annoy the neighbours thow, I will start with a motor vehicle alternator and 12v battery as a learning curve, no doubt you will hear about all my problems.
By for now.

On the positive side, at least you don't have to wait for a 120 knot breeze before they start working efficiently

You'd probably have some very nasty gyroscopic effects from such heavy blades too.

747 wind turbine

Hi there. Wow imagine a 747 wind turbine, Rollsroyce or what, super single cristaline metal alloy blades, if i was a neighbor, and saw it out my window i would approach you as to how to get the blades to make one, its got to be super afficient wind turbine. Dave. PS thinking big is great.
