[0042] Combine below Figure 1 to Figure 7 to characterize the blade surface. like figure 1 , figure 2 As shown, Z is the axis of rotation, the first curve AB is a smooth and non-inflection point concave curve that is coplanar with the axis of rotation and does not intersect, and its concave surface faces the axis of rotation, and one end point B is close to the axis of rotation, called the proximal end, and the other end point A away from the axis of rotation is called the distal end. Take any point P1 on the first curve as a tangent, the angle α between the tangent and the rotation axis is less than or equal to 90 degrees at the proximal end B, and greater than or equal to 0 degrees at the distal end A. Obviously, α equal to 0 degrees means that the tangent at the distal end A is parallel to the axis of rotation. As the point moves from the proximal end B to the distal end A, the angle α decreases monotonically. If the first curve AB can be represented by a function, i...

[0062] like Figure 12 As shown, the single blade can also form a single blade turbine 2 . The single-blade turbine 2 only includes a turbine blade 21 composed of a curved surface of the third blade. The turbine blade 21 can be regarded as a multi-blade turbine with infinitely small gaps between the blades, which is a complete reference surface with thickness, in the form of an antenna pot-shaped surface. , there is a cavity near the rotating shaft 22, or a guide hole is provided for fluid flow.

[0064] like Figure 13 As shown, a plurality of single-blade turbines 2 can form a coaxial laminated turbine 3, and the coaxial laminated turbine 3 can also be regarded as a multi-stage turbine formed by a plurality of single-blade turbines 31 in series around the rotating shaft 32, that is, the diameter Different single blades are coaxially stacked together, leaving a gap between them. The law of the gap still follows the general law of the blade gap, that is, along the blade surface from the rotation axis to the radial edge of the blade, the blade gap is getting smaller and smaller, but the smallest. Gap is greater than zero. Figure 13 The section view of some blades is shown, and the law of blade clearance can be seen. In practice, the leaf density may be much higher than Figure 13 shown. Under the premise of not significantly affecting the performance, some special nodes between the blades on the blade surface are also allowed to have mutually fixed structures to enha...
