In this study we want to propose an active logic that, continuously, optimizes the configuration of the propeller and motor speed taking into account changes in resistance and wake. The working principle of the control system is based on the measurement of the torque absorbed by the pro-peller and the engine speed, to obtain the actual thrust and advance speed coefficients. Based on these data, the controller identifies the configuration of the propeller for the best performance of the entire propulsion chain, from engine to propeller. Moreover, in addition to torque and speed limits of the en-gine, the control system chooses pitch angle taking into consideration the propeller’s cavitation.

Abstract
In this study we want to propose an active logic that, continuously, optimizes the configuration of the propeller and motor speed taking into account changes in resistance and wake. The working principle of the control system is based on the measurement of the torque absorbed by the pro-peller and the engine speed, to obtain the actual thrust and advance speed coefficients. Based on these data, the controller identifies the configuration of the propeller for the best performance of the entire propulsion chain, from engine to propeller. Moreover, in addition to torque and speed limits of the en-gine, the control system chooses pitch angle taking into consideration the propeller’s cavitation.File | Dimensione | Formato | |
