ABSTRACT:
The present invention is a multipath power transmission for use in an aircraft nosewheel steering system. Two planetary gear sets, together providing the power to steer the nosewheel, have their ring gears externally meshed to balance the power delivered by each of the planetary gear sets. As a result, each planetary gear set must only be sized for fifty percent of the rated load, thereby minimizing weight and size, both of which are critical in an aircraft.
