I don’t know…

one: the 5 MWt provided by the typical FF unit to the airstream is not going to generate the amount of thrust that the 5 MWe gets from the propeller.

two: the pinch is, perforce, insulated by a vacuum. You’ve got to get the helium out of the core and to a cold plate exposed to the airstream first…

Undoubtedly there will be optimized aircraft engines as people develop the tech after functional FFs are introduced. Things I couldn’t dream of now…

The point here being that, given the standard starting stats for the FF, right off the bat you’ve enabled a revolution in the air freight business and air passenger transport won’t be far behind…
