I have read this question:
The compressor generates a certain volume of air at a high pressure. In the combustion chamber, this air is heated - this leads to a much larger volume of air. Looking at a section of the turbine (tapering to smaller section as compressor stage approaches combustion stage) we see that this further encourages high density mass flow into the combustion stage. At the exhaust stage the pitch of the fan blades is such that work is done by the fast moving air without causing a large pressure drop. In other words - it is "easier" for the air to go out the back. But since there is far more air coming out the back (added a lot of volume by burning fuel) the fast that it is working "less hard" on the way out doesn't stop the engine from producing power / thrust.
This is a very nice explanation why turbines work.
Though, I have not found any description on this site why turbines are more effective then propellers on airplanes. As I understand most of modern airplanes (that fly at high speeds) have turbines instead of propellers, and I have not even found to what extent turbines are better then propellers. As I understand, turbines give more throttle then propellers, but i have not found any explanation why. Or the given throttle per used fuel is more efficient.
I have found this:
This combines a propeller with a turbine. But it still gives no explanation why turbines would be more effective then propellers (if they are at all).
- Why are turbines more effective than propellers on airplanes?
