No, they don't |
Turbines pull air over the wings which aids in lift. How much I don't know. I agree the main thing the turbine does is create a low pressure in front of the plane which causes the rear air pressure to push the plane forward. But, the force of air backward acts on the wings the same way the moving plane air acts on the wings.
I'm sure if you reached the 175mph and stopped the engines the plane wouldn't lift. You would have to increase speed. But yes air moving across the wings is the only thing lifting the plane, but we are discussing where that air is coming from.
