ABSTRACT:
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 structure can be pivoted in respective bearings to effect the pivotal movement of the propellers and wing portions for either vertical take off and landing or for horizontal flight. The pipe structure is built by pipes without bends in order to make the cleaning of the interiors of the pipes from dirt and from remainders of welding possible. Ribs and holding portions are provided on the structure for assembly and/or disassembly of the wing portions of the pipe structure.
