Abstract
A device for ventilating and electrically powering a computer of an engine of an aircraft, the device including a feed mechanism feeding air to a proximity of the computer and a fan connected to a drive mechanism and configured to generate a stream of air for ventilating the computer. The fan is mounted in the air feed mechanism, and the drive mechanism includes an electrical machine configured to operate as a motor for driving the fan, and as a generator for powering the computer, a rotor of the machine when operating as a generator being driven by the fan, which is itself driven by a stream of air flowing in or leaving the air feed mechanism.
