Reply to comment by InappropriateTA in TIL that passenger jet engines produce most of their thrust from fan at the front, not from the jet exhaust, and that this is called a high-bypass engine. by Rilot

Thrust is not generated by the turbine. Turbine spins the compressor and fan. Thrust is generated by the fan and by the combustion of fuel in the combustion chamber.

20-30% of the thrust comes from the core, or turbine. The other 70-80% comes from the fan.

His point is all the energy is coming from the core. Its just being captured by the turbine and used to spin the fan.

Fan via link to the turbine, I mean.
