Abstract
This control device for a propulsion system, comprising means for calculating a blade-pitch setpoint of at least one propeller of the propulsion system, the calculation means using a performance predictive model of the propeller taking account of at least one flight speed for adapting a blade-pitch angle setpoint, is characterised in that the performance predictive model of the propeller is configured to use polar charts implemented in the form of a mathematical law.

A control device for a propulsion system, comprising means for calculating a blade-pitch setpoint of at least one propeller of the propulsion system, the calculation means using a performance predictive model of the propeller taking account of at least one flight speed for adapting a blade-pitch angle setpoint, characterised in that the performance predictive model of the propeller is configured to use polar charts implemented in the form of a mathematical law.
A method for controlling a propulsion system, comprising a step of calculating a blade-pitch setpoint of at least one propeller of the propulsion system, during which a step of predicting the performance of the propeller is performed taking account of at least one flight speed to adapt a blade-pitch angle setpoint, said prediction step being characterised by the use of the polar charts implemented in the form of a mathematical law.
