Well we learn something new every day! I didn't realise that there were so many developments going on. It is good to see that there is so much R & D about; it gives me faith in the system.
Just one point on a slightly different note; in the traditional piston 4 stroke engine used in aviation, generally a Bendix magneto is used as it produces its own electricity, so in the case of total electrical failure the engin can still run. But this system was designed aeons ago with, seemingly little or no development. Has a brakerless system, similar to that used in car engines been developed yet? Or is anyone working on designing one? I think that the benifits of this type of system (better quality spark, better fuel consumption, less maintenance etc.) should be available to aviation sa well as the motor world. What do you think?
