Experimental determination of the hydrofoil's angle of attack in the case of a turtle-like Autonomous Underwater Vehicle

In this paper a turtle's hydrofoil 2 DoF's mechanism (degrees of freedom) is implemented and tested in a water channel as a propulsion system for an Autonomous Underwater Vehicle (AUV). The experiments carried out showed an optimal empirical value of the angle of attack for the turtle's hydrofoil that is compared with the theoretical value. The hydrofoil path used in the tests was a linear displacement and the optimization of this path will be analyzed in future works.
