WebbThe function of rotor is to provide velocity to the gas through blades that are attached to a rotating disc. Depending upon the desired output, these blades can be either forward-leaning, radial or backward-leaning. Since backward-leaning blades provide the widest range of efficiency, most of the multistage compressors use them. 2.
