ABSTRACT:
The compressor comprises an impeller and a diffuser with blades (vanes) of a constant thickness, arranged around the circumference of the impeller and diffuser. In the zone between the entrance edge of each blade (vane) and its center in a radial direction the angle between the pitch line in the longitudinal section of each blade (vane) and the tangent line to an imaginary circle drawn through any point of said pitch line from the center of the impeller axis of rotation is equal to the entrance angle of the blades (vanes). In the remaining zone of the blade (vane) this angle varies according to a quadratic parabola.
Each pair of adjacent blades has blades of a different length, the exit edges of the blades being located on one imaginary circle drawn from the center of impeller axis of rotation while the entrance edges of these blades lie on two imaginary circles drawn from the same center.
