Abstract
This paper primarily concerns with the review of Azimuth thruster, its types, architecture, working along with its advantages and disadvantages. An Azimuth thruster is an arrangement of marine propellers placed in pods which can be rotated to any horizontal angle (azimuth). Joseph Becker, invented the Z-drive azimuth propeller first in 1950, whereas this kind of propulsion was first patented by Pleuger in 1955. The ships fitted with this system give better maneuverability than a fixed propeller and rudder system. This assembly consists of the podded propeller connected to a motor and an azimuth well to support the propeller. As thrust acts on the assembly, the well is supported by structures like brackets, struts etc. Furthermore, literature survey about the work doneon Azimuth Thruster till datehas been mentioned. There has been sufficient research on the optimization of design of propellers, performances and efficiencies at various parameters, but there is scope of improvisation in the design of supporting structures related to the assembly in order to optimize the weight and increase the efficiency of the working of the propeller, as well as to mitigate the problems faced while assembly.
