Aircraft propulsion system comprising at least one activatable wave attenuation device

Abstract

Aircraft propulsion assembly comprising at least one activatable wave attenuation device. The invention relates to an aircraft propulsion assembly comprising at least one activatable wave attenuation device which includes at least one analysis system (70) configured to analyze a first wave (66) produced by a motor of the propulsion assembly and / or at least one of its characteristics and generate a control signal (S76), as well as at least one wave generator (72) configured to, upon receipt of the control signal (S76), generate at least a second wave (74) out of phase with respect to the first wave (66).
