DEVICE FOR REDUCING AERODYNAMIC DISTURBANCES IN THE WAKE OF AN AERODYNAMIC BLOW PROFILE WITH VARIABLE DISTRIBUTION TO EXTRADOS AND INTRADOS

摘要

The invention relates to a device for reducing aerodynamic disturbances in the wake of an aerodynamic profile. The device comprises a first nozzle (51) of air ejection disposed on the extrados (EX) of the profile and a second nozzle (52) of air ejection disposed on the intrados (IN) of the profile. A first blowing chamber (41) is fluidly bonded to the first nozzle (51) and a second blowing chamber (42) is fluidly bonded to the second nozzle (52). Air supply means are configured so as to be able to vary the distribution of air between said first blowing chamber (41) and second blowing chamber (42). The distribution between the first and second nozzles (51,52) of the blown air can thus be adapted according to the use situation of the profile, for example according to the flight phase of an aircraft equipped with such a profile. The invention also relates to an aerodynamic profile, a mast supporting an aircraft propulsion assembly comprising such an aerodynamic profile, and an aircraft.
