I have been reading about how future planes might have electric engines and was surpirsed by the following
Quote:
Unlike the early days of jet aircraft, today’s airliners only get a fraction of their push from jet thrust. Most of the propulsion is provided by the giant fan at the front of the engine, which accelerates air just like a propeller.
These high bypass ratio fans are powered by the jets, and there’s no reason they couldn’t be powered by electricity instead.

I always thought that the project would be limited to prop aircraft when using fusion power, but from this I would assume that most subsonic jets would have the potential for conversion as well.
