This was also one of my fixed dilemma...
Is there someone that can explain why a High by pass turbofan is not the same as a propeller???
When we study propellers we know that they are affected by the efficiency of propulsion related to the a/c speed. Jet engine instead aren't.
Why the fan stage is not considered to be the same as a propeller.... the only difference looks to be the number of blades!!!! hence it should behave as a propeller!!!!
The turbofan should have a great dependency on the a/c speed too... instead it doesn't.... why?
