Variable Frequency Generators
The manuals for the aircraft I fly state that the AC generator does not output at a constant frequency. The range is around 200-800Hz. This has left me a bit confused. Firstly, can electrical users in the aircraft accept such variable frequencies? We have power outlets that clearly mention that they're on a fixed frequency of 60Hz. What's going on? The manuals don't mention when or how this variable frequency power from the AC generators are converted to a fixed frequency. I believe that all the users of electricity must need a fixed frequency.
Secondly, what's the benefit of a VFG vs an IDG or alternator/generator with a separate CSD THANKS |
