The main objective of the project is to design and research a helicopter rotor mechanism. Applying these approaches correctly and successfully to a complex design, like a helicopter rotor mechanism, where the aerodynamics are complex and changing and the design space has many dimensions, is the current challenge. As optimization methodologies sometimes need for a starting design point, the design phase is just as important as the optimization process. The first optimization of rotors employed simpler computational fluid dynamics (CDF) approaches.
