DA42 Electrical Generation Question?
Hi guys,
Hope your well.
I have been reading about the electric systems for the DA42, and would just require some clarification on some parts written in the AFM:
If I can quote the following:
7.10.1 GENERAL
The DA 42 has 28 Volt DC system, which can be sub-divided into:
- Power generation
- Storage
- Distribution
- Consumers
Power generation
Power generation is provided by two 60 ampère alternators (generators) which are mounted on the bottom left side of each engine. The alternators are driven by a flat-belt.
The power output line of the left-hand alternator is connected to the 'LH main bus' via
Now it says that is has a DC system, and says that the power gen is from altenrators (gens). However going back to my basic understanding of electrics, do alternators not only produce AC ? So where does the DC come from?
Also, the aircraft has an "alternator control unit" to ensure constant power - which might suppose that it is AC, but obviously not.
So, could I ask what is going on here? Is it AC converted to DC? Or the alternators produced DC straight as well? Or is ot the wording I am not seeing?
Thanks alot guys
