The thrust of an airplane changes the speed of the airplane, or you can look at it as it is increasing the airspeed relative to the airplane. The airspeed across the wings is only as much as the thrust allows it to be. The airspeed across the wing is what produces thrust, and I realize how it does so, via either pressure difference, camber, angle of attack, or a vortex lift system. What my question is, how can it be possible that a plane can produce more force in lift, then it has in thrust. I ask because the lift is directly dependent upon the thrust, so where does the extra force come from? Can someone break it down, via both calculations, an example, and a conceptualization? Thank You All Very Much!
