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.
