re: FADEC control alternators
Are these the same as the FADEC EECs? Just want to make sure. If so, I'm told they produce 300W at 2300 RPM (by a forum member). Yes, they need to be pushed through one of the TRUs to get D
That is usually referred to as a PMG permanent magnet generator, not sure off the top of my head about wattage, frequency, voltage. The main purpose is to supply power to the FADEC, Full Authority Digital Engine Control in the event of a power failure. This supplies power to that fly by wire engine to allow a minimal level of control. Think I replaced one once on another FADEC engine, it is a small unit. They are very reliable, if they were not I could probably tell you more about them. Suppose I will go back into the books tomorrow on the GE90
