Flexibility and speed to market are the keys to successful product development. For marine propellers, these goals are achieved though iteration of design software and prototyping. In this thesis, an expanded propeller design code, OpenPVLSW, which was developed based on the Open propeller vortex lattice lifting line code (OpenPVL), was improved to include propeller geometry generation into SolidWorks, thrust simulation with CosmosFloWorks and strength assessment with CosmosWorks. The new code OpenPVLSW is described in this thesis. In the OpenPVLSW, a parametric design technique and a single propeller geometry generator are completed in MATLAB, and a propeller blade geometry file for SolidWorks is created after running the design program. -- The purpose of this study is to extend the use of the original OpenPVL code not only for the propeller design, but also to achieve the thrust simulation and strength check using SolidWorks tool package, CosmosFloWorks and CosmosWorks. A propeller geometry, which is provided by Oceanic Consulting Corporation, is simulated to predict propeller thrust using CosmosFloWorks. A case study designed an AUV propeller and simulated the thrust with CosmosFloWorks to prove that the OpenPVLSW code provides perfect propeller geometry and a reasonable simulation result of thrust.
