I am having a hard time getting my head around this concept and if it would even work and was hoping a sharper mind could help. I have seen it work by driving the sun but can it work by driving the ring. In this example (see attachment) the drive is in yellow. A propeller is attached to the Carrier and another propeller having reverse pitch is attached to the sun. The torque from the Carrier prop turns the planets driving the Sun prop in the opposite direction. We will assume both props require the same torque to turn at the same speed opposite of one another. Ideally if one prop did consume more than the other the mechanism would compensate by balancing the loads by speeding up the other. This mechanism would use friction elements as opposed to gears so we need not be concerned about the correct number of teeth. The question is 1) will it work? and 2)with a ring diameter of 100, what would be the diameter of the sun and planets and what would their individual reductions be?
