Do a jet engine’s turbines actively pull air into the engine once the turbines begin to spin? (Both during the starter motor phase and also during flight at higher speeds)
And does the front half of the engine produce a substantial amount of drag as it is travelling at high speeds? (not including the thrust coming from the back)
If anyone could help it would be much appreciated!
*I’m thinking about axial and turbofan jet engines, but am curious about all types, *apart from pulse jets*
Cheers!

the only jet engine that doesn’t actively pull air through the inlet would be a ramjet.
the others have compressor stages and spin faster when the aircraft attains higher speed. commercial jet engines are turbo fans where the fan acts like a propeller to push the aircraft faster.
