Word is that it has landed safely.
Why in the turbines can not put a metal mesh like those that protect tweeters?
(Yes, they would be much bigger ........)
Can someone explain it to me ?
The actual reason is that the mesh would ice over.
Someone with more experience in aerospace engineering can correct me on this, but given the insane flow of air through a turbine I can only imagine that the forces on this "mesh" would be absolutely immense. I suspect that it would be extremely loud as well.
6L6 is right about the icing, and given the amount of airflow, it'd probably be nearly impossible to keep it hot enough to keep the ice off.
It's an obvious concern so if it was practical to implement, it would have been already, right?
