Why I was lying in the bath just now (heated by solar collectors, powered by Navitron auxiliary gear) I was wondering what they will do with all of these aircraft that are no longer needed. How about converting the A380 wings into turbine blades? No need for variable pitch, it will take 600 mph, had flaps for low wind operation, aerolons, and other gismos....It carry's 300 tons... 


Off grid; 4KWH install charging Rolls 24v 1000 A.H. batteries with 3 Tristar controllers. 3KW Victron Inverter with FIT meter on output. Relay driver automatically opens circuits as battery charges. 6 x 15 experimental solar collectors feeding 250 L. tank.  Angus wood gasification boiler.

You must have had the water too hot and hallucinated fingers crossed!.

The wings have a good scrap value . Mind you, with the on board fuel tanks. The WT could have a jet engine fitted in it to propel the blades like when there is no wind.  chocolateteapot

  • Wingspan is only 80m - with a highly optimised blade that might get you to 2.5MW, reality is that you're much lower with these because they're designed for a completely different flow regime. The big boys of the wind turbine world are twice as long as this already and growing fast.
  • It probably does need variable pitch - the flaps & slats help a lot, but probably not enough given the wide range of flow conditions a wind turbine sees.
  • Weight is a killer - the A380 is a 500 tonne aircraft. Spinning those wings on top of a very thin tower and applying variable loads to them is structurally rather nasty. You can probably do some interesting things (active gust response, etc.) but not enough to compensate.

Right now Airbus are doing far more interesting and valuable things, and probably don't want to be reminded of the A380 fiasco.
