Ventilation of an internal compartment of a fairing device of a propulsion assembly in an aircraft moving at low speed on the ground or when it is stopped cannot be provided optimally using a conventional dynamic air intake. To solve this problem, the use of a fan housed within the internal compartment is proposed, for which the fan propeller can alternately be coupled to an accessory gear box to drive the fan propeller, and uncoupled from the accessory gear box when it is unnecessary to drive the fan propeller or when it represents a danger.
