Case B: Failure of a Large Air-Conditioning Fan Blade
Introduction The authors acknowledge the work done by Hwa-Perng Kao on this case study.In some air-cooling systems for large buildings the hot air is passed through a water-cooled chilling tower. The large volume of air requires a relatively large fan, consisting of several blades rotating around a common axis and operating as a turbine fan. A schematic drawing of such a fan is shown in Fig. 7.12. The neck of the blade is the location that sustains the greatest centrifugal and bending stress, and the subject of…
