[0019] The present invention will be further described below with reference to the drawings and embodiments.
[0020] Such as figure 2 , As shown in 3, an H-shaped vertical axis wind turbine with coaxial jet blades includes a jet blade 10, a rotating shaft 11, and a connecting rod 12. A plurality of coaxial jet blades 10 are respectively connected to a rotating shaft 11 through a connecting rod 12, and the rotating shaft 11 is connected to a generator 13. The multiple coaxial jet blades 10 move along the rotation track L, and drive the generator 13 through the rotating shaft 11 to rotate and generate electricity.
[0021] Such as Figure 4 to Figure 6 As shown, a high-pressure air cavity 1 is opened near the leading edge of the coaxial jet blade 10, and a low-pressure air cavity 2 is opened near the trailing edge. The airfoil surface of the coaxial jet blade 10 is 3% chord length away from the leading edge. The first and second air injection ports 3, 4 are opened respectively an...
