In contrast. If you can agree that the backwash from engines is greater than the downwash from the wings. Then it follows that the thrust form the engines is greater that the lift produced by the wings.
Are you saying that the wing produce almost 2.5x as much upward force than the maximum engine thrust (which is used to push the airplane forwards and up)?
That's not possible because it breaches the physics principles of conservation of energy, momentum and force. Wings cannot create a force...
Engineers are confronted with two apparently true but contradictory statements for airplanes in flight:
a) Lift must equal the weight of the airplane (Lift = Weight), based on Newtons 2nd Law of motion (i.e. Force = ma); where gravity is used to calculate weight (i.e. Weight = mass x...
