An electric generator for an aircraft includes a sealed casing, a rotating shaft, and a ventilation device, which has at least one orifice configured to place a chamber positioned inside the rotating shaft in communication with the exterior of the sealed casing. For at least one orifice, an inertia sealing system is configured to occupy an open state when the speed of rotation of the rotating shaft is below a given threshold, in which state the sealing system is spaced from the orifice, and a closed state when the speed of rotation of the rotating shaft is above the given threshold, in which state the sealing system seals the orifice.
