Wind wheel type helicopter

The invention relates to a wind wheel type helicopter, which belongs to aircrafts and is characterized by: vertical take-off and landing, simplicity and reliability, low cost. The basic structure consists of a wind wheel composed of several wind plates f and a wheel shaft (1); a variable flow hood (2); a body (4); 4 rudder propellers (5) and a handle (7), etc. The lift principle of the invention lies in that: the variable flow hood is a partially closed shell structure, the wind wheel is nested into the variable flow hood and is driven to rotate by an engine, due to the action of the variable flow hood, the wind wheel can generate an efficient unidirectional thrust on the wheel shaft (Note: the system is subjected to aerodynamic solid mode experiment, which proves that the system can produce an effective unidirectional thrust). With the principle, the helicopter that ordinary people can use with reassurance can be manufactured.
