Abstract
The invention relates to an aircraft propulsion assembly (), comprising a single gas generator () and two fans () drive in rotation by the gas generator () and offset on either side of a vertical plane passing through a longitudinal axis (X) of the gas generator, the rotational axes of the fans lying substantially in the same fan plane. According to the invention, the propulsion assembly () comprises an air inlet fairing formed upstream of a nacelle () connecting the fans, said fairing () having, between the fans (), an air inlet opening (') lying substantially perpendicular to the fan plane and on either side of this plane, the propulsion assembly further comprising an air supply device configured so as to supply the gas generator () with a part of the incoming air and to take off, from the remaining part of the incoming air, a cooling airflow intended to cool elements of the propulsion assembly and/or a wing supporting the propulsion assembly.
