Could we make a supersonic electric airplane?

Click For Summary
SUMMARY

The discussion centers on the feasibility of creating a supersonic electric airplane. Participants highlight that traditional electric aircraft utilize fans for thrust, but achieving supersonic speeds presents challenges, particularly in accelerating air to supersonic velocities. The conversation suggests that while turbofans can operate at supersonic speeds, integrating an electric motor to replace the inner turbine may be a viable solution. Theoretical physics insights are shared, emphasizing the need for engineering perspectives on this innovative concept.

PREREQUISITES
  • Understanding of electric propulsion systems
  • Knowledge of aerodynamics, particularly at supersonic speeds
  • Familiarity with turbofan engine mechanics

Hi guys, I've been reading a bit and watching a few youtube videos on electric aircraft, but have come across little to do with supersonic aircraft.
As far as I understand it an electric aircraft would use basically fans to push air behind it and as such generate thrust. The problem would be that once you go supersonic, in the rest frame of the aircraft, you would have to acclelerate the air you're pushing behind you to supersonic speeds, which I am not sure would be possible with such a propellor engine.
I study theoretical physics and not engineering so I am interested to see what responces you can give me and possible other ideas you guys come up with for a supersonic electric aircraft.
Thanks in advance to any responces.

Turbofans work at supersonic speeds and their main thrust comes from the fan, you can replace the inner turbine with an electric motor.
