This thesis deals with the development and design of a mechanism used to change the geometry of impeller blades in radial fans. Firstly, a suitable design was selected and then constructed taking into account the forces and loads applied. The blade consists of two parts - fixed, and movable. The movable part extends or retracts behind the fixed part of the blade, changing its length and therefore the operating characteristics of the fan. The simulation part of the work deals with the effect of the changed blade geometry on the fan performance at one particular operating point. The results show a slight reduction in performance, but on the other hand the fan is operable under a wider range of operating conditions. The conclusion of the paper suggests the need for further research to gain a deeper understanding of the capabilities of radial control mechanism fans.
