SolidWorks. This modification will clearly save users' time, especially when a number of design iterations need to be implemented. Solidworks allows users to design a specific propeller hub and create a 3D-printable file for rapid prototyping to produce a propeller for a modcltesting. The CosmosFlo\Vorks package allows users to simulate the propeller working in a specific fluid environment through CFD. The simulation helps the designers to predict the thrust of the propeller as part ofthe design cycle. The CosmosWorks packagc will use thc pressure results as an input of FEA to check the propeller strength. 7.2 Future Work Add propeller hub design Function in the OpenPYL_SW code Coating with glue can increase the strength of ASS material. Future experiments can be conducted to find out the detailed data for the increased strength. Usc SLS rapid prototyping technology to fabricate an ideal marine propeller and test its perlonnanee Test propeller's thrust and compared with the CFD result Test stress at the root ofthe propeller blades Fabricate a propeller with two methods. One is produced by CNC machining with cutting ofT material to left a solid part. Anothcr onc is produced by melting material layer to layer to fabricate the propeller part. Test the stress of the two propellers with different fabrication methods. Much more deflection analysis will be applied in the future work. 106
