I'm confused.
You're using a fan to send wind to power a windmill?
he he he, that is a good way to put it
the jet blows on a free spinning turbine, but that free spinning turbine is connected by a hard shaft to a generator
you excite the field to the generator to increase voltage and amperage, keeping the rpm's of the generator constant, while the engine goes up to full speed, 10,000 rpm's
each engine makes approx 25 MW in 15 minutes
twin packs make 50 MW
