The invention relates to a wing ring, a wing ring mechanism and a method. As to a conventional middle shaft type wind wheel and a rotary wing, wing blades are supported only by a force arm on one side of a middle shaft, the whole torque and load are borne only by one central shaft, therefore, a 100,000 kilowatt-class electric generator or a kiloton helicopter cannot be driven; if the middle shaft is abandoned from the wing ring, a ring support is directly used for supporting the wing blades from two sides, the total area of an effective ring section can be increased by a plurality of times to hundreds of times, a plurality of groups to hundreds of groups of track cars are used for sharing the torque and load which are only borne by one shaft, and the torque is also increased by a plurality of times to hundreds of times, therefore, the capacity of a single wing ring wind turbine generator can exceed that of a largest steam turbo generator, and the maximum take-off weight of a wing ring aircraft can reach tens of thousands of tons; a group of buoyancy lift mechanisms is arranged in two wind layers (opposite in wind direction) of a reverse wind group respectively, and the two groups of the buoyancy lift mechanisms are connected through ropes, connecting rods or supports to form an opposite-pull flying mechanism; and the maximum take-off weight of the wing ring opposite-pull flying mechanism can reach hundreds of thousands of tons, and the maximum generating capacity can be ten times of that of the three Gorges project.
