Methods for minimizing the effects of pylon induced disturbances of the airflow at the propeller blades (2) of propeller propulsion devices (3) attached to an aircraft component (5) by means of upstream pylons (4), comprising steps of injecting fluid on the zone of the propeller blades (2) from the rear part of said pylons (4) for minimizing the effects of said disturbances detected through the values of a first set of parameters such acoustic pressure and vibration in the aircraft structure and vibration in the propeller blades (2) that are obtained continuously or according to models linked to one or more parameters of a second set of parameters indicative of the aircraft flight conditions such as flight altitude, flight speed propulsion power, propeller rotation speed obtained from a tachometer signal, ambient temperature of the air. The invention also refers to systems for implementing said methods. |
