Somehow you can get 100,000 pounds of vertical force by only supplying 30000 pounds of horizontal force. There's gotta be a way to make perpetual motion machine out of this.
However, one fact is helping me understand:
Notice helicopters always have engines that can produce as much thrust as they weigh. If I'm wrong on this, please correct.
I'm guessing the difference is taken from the energy in the air itself. Lower energy air (turbulent) is produced and remains until heat and gravity restore said energy. Helicopters can't benefit from this in a hover.
Hey, I can guess, can't I?
