Review and outlook
HélCo project : an innovative project to design a composite propeller

The project achieved its objectives. In academic terms, it demonstrated the feasibility of co-simulations (both in terms of the resources required and the precision expected), and provided elements of validation and understanding of the physics involved (in particular through experimental data). In terms of methodology, it has contributed to the development of a calculation chain to support the design of deformable load-bearing profiles. Technologically, it has helped to develop a prototype propeller with attached blades, themselves made of composite material, and a manufacturing process for these blades. During sea trials, the crew appreciated the composite propeller's smoother rpm change compared with the metal propeller. Finally, at the end of the real-life tests on...
