Axial-flow Compressors and Fans  161


























                          FIG. 5.16. Weinig’s results for lift ratio of a cascade of thin flat plates, showing
                          dependence on stagger angle and space/chord ratio (adapted from Wislicenus (1947).







































                          FIG. 5.17. Two simple types of axial-flow fan and their associated velocity diagrams
                                                  (after Van Niekerk 1958).
