Thrust and lift are not same, are not different, the axial component of lift is the thrust;
otherwise, what is thrust, how do you get this axial force? This lift that I am getting, the
component of that in the axial direction is what I call an element of thrust by any point here,
that thrust integrated over the whole blades, all blades, gives me the total thrust on the
propeller- is that clear? I am also loosing something in the form of drag, so, ultimately, the
propeller efficiency will be, is a ratio between lift and drag- but have you understood how lift
is being generated?
