An aircraft has a pair of wing portions with propellers of a propeller pair which are driven and synchronized by a fluid transmission between the power plant and the propellers. A fluid line structure keeps most components of the craft together and consists preferredly of three pipes which are also utilized to carry the driving fluid to and from the motors, to hold the motors and to hold the wings. The take over of a plurality of functions by the interior pipe structure reduces weight and secures safe and economic operation of the craft. The pipe structu...


An aircraft, which comprises, in combination, a body, at least one power plant, at least four propellers, at least two pairs of wing portions, a transmission between said power plant and said propellers with said transmission leading equal portions of power from said power plant to said propellers, whereby said transmission transfers at least four portions of equal power and rate of speed individually each one to one of said propellers to synchronize the rotary velocities of said four propellers to equal speeds and forces, arrangements to pivot the axes ...
