The flag is a metaphor for country, thought you could figure that out.

When American Citizens with dual citizenship pledges allegiance
to the flag, to which flag do they pledge allegiance too?

Hmmm, how does that pledge begin?  Oh yes  "I pledge allegiance to the
flag of the United States of America..."

I hope that answers your question.

 

Horizontal vs Vertical
..So if torque is sorta 'force x distance', wouldn't a vertical axis set-up
be able to generate more torque at the hub?  Thereby being able to be
smallish  in diameter,  able to turn a larger (power) generator, with slower
rpm.  Rather than using 'wing' airfoil type that generates torque on a
diminished forward angled lift vector, thereby necessitating huge rotor
diameter systems, extremely elevated on a pedestal for ground clearance.
And talk about noise...gawd!!!

Forward tilting........think helicopter or autogyro(blades powered by wind
movement)....when power is applied to the blades by a engine or electric
motor.
The bladedisc is tilted forward......but in power generation, as in the
blades going into autorotation to turn a gernerator.
The blade dics is flared back.
You can actually see an example of that with gyro trainers, that are towed
behind a car at a flying club.
(Since landing and takeoff is part of flying ,that needs to be learned.)
Or in air demos in which the powered gyro  will nose into a fairly high wind
and appear from the ground to hover.
Indicated airspeed tells you that are doing 32+ mph.......some airplane guys
like Lindbergh, did the same thing by unknowingly flying his airplane
backwards. When he "discovered" the jetstream the hard way on his first
transcontinental attempt from NY to LA.And ending up in the Atlantic
when the cloud base cleared away.....forgot how many miles, but a long way
offshore.
