Tornado generating propeller, tornado generator and tornado demonstration device

摘要

Problem: Tornado generation by the conventional local exhaust technology is necessary in the free space such as the natural tornado which occurs in the sea etc.such as room, container, induction officer, injection equipment, fan case, etc., and it is complicated, and the elongation of the tornado to the size of the machine and equipment is small. The main purpose of the present invention is to provide a tornado generating propeller, tornado generating machine and tornado demonstration device for generating tornado only by a propeller. In order to achieve the above purpose, the blade of the structure comprising a centrifugal propeller blade and an axial propeller blade is used as a wing of a tornado generating propeller, and the radius is passed through the inside of the blade of the tornado generating propeller By accelerating the direction, the increase of the swirling down flow can be enhanced.
