From google-patent's translation: "The invention relates to a flying machine with sailwheels that collapse and unfold, and in particular has the purpose of creating a machine which, like a free balloon, offers the same resistance to air currents in every direction. The known flying machines with such sail wheels have the disadvantage that their flapping surfaces exert control effects when the aircraft moves obliquely to the wind in any direction so that it sways back and forth without the operator being able to compensate for these swaying with the rudder. This disadvantage is avoided by the invention in that the sail wheels are arranged in a circle around a common vertical main shaft in such a way that they form an annular surface that is as closed as possible in the unclamped state."
