Abstract
Nowadays, many ships are made using Controllable Pitch Propellers (CPP). Both for ships and offshore structures, usually are made of ducted CPPs. The characteristics of CPP has many differences of substantial items from fixed pitch propellers. There is no systematic information given on the propeller blade spindle torque for CPP, it is including for all possible blade pitch settings which is from full positive pitch to full negative pitch and over the complete four quadrants. The objective in this thesis is finding the propeller performance of CPP type C4-40 P/D 1.4 with various distribution pitch using CFD. The geometry of the propeller is produced by MARIN application that just giving input parameter which is the diameter of the propeller. The model has been manufactured; in case it will be done experimental process on the next opportunity. First of all, the author made the 3D model of the propeller and make it solid file using the rhinoceros and solidworks. After that, the model should be meshed on Hexpress before it is going to be simulated in Fine Marine. The meshing quality of the propeller is around 1-2 million cells. In Result, all of events are happening in this simulation. At first, the performance of distribution pitch +1.6 is getting higher than the original pitch. The thrust produced by the propeller are higher and so does the moment. But in distribution pitch +1.2, there are event of propeller gave the thrust negative which mean force backwards. It is happening while J1.2 and J1.4, the thrust is negative but the moment still positive. It can be seen like the propeller try to stop the movement forward of the ship. There are ahead, crashahead, backing, and crashback happening in this analysis, which can be shown in four quadrant graphs.
