Hi,
I'm having a little trouble understanding how these can increase the thrust of a turbofan. My understand is that they utilise the fact that the tips are moving faster than the center parts. Therefore they are able to accelerate a greater mass flow of air which translates into greater thrust.
Is this because these engines are generally high bypass, where most of the thrust comes from the bypass air. This would mean that if the tips of the blades are acceleration more air, more air will be bypassed which produces more thrust?
Or is could be completely wrong in my whole understanding.
Thanks
