The compression is the easiest part to emulate. The hard part is the enormous amount of heat you need to generate and quickly transmit into that compressed fluid. Combustion is great on both accounts for that, but you could do it electrically as well given a sufficient power supply.

Without a combustible fuel in the picture, isn't it more efficient for the kinetic energy of an electric motor to directly spin fan blades or turboprop propellers, vs converting that energy to heat?
- idiotsecant 5y agoMaybe! There are certainly some operational regimes where it would be less efficient to spin props than it would be to shoot out hot gas, but they might be places where an electric aircraft wouldn't ever operate.
