The experts advocate an approach to lift by Newton's laws.

  • The experts advocate an approach to lift by Newton's laws.

  • Any solid body that can force the air downward clearly implies that there will be an upward force on the airfoil as a Newton's 3rd law reaction force.

  • From the conservation of momentum for control Volume

  • The exiting air is given a downward component of momentum by the solid body, and to conserve momentum,

  • something must be given an equal upward momentum to solid body.

  • Only those bodies which can give downward momentum to exiting fluid can experience lift !

  • Kutta-Joukowski theorem for lift.







Flow past any unknown object can be represented as a complex potential.





To Create IRROTATIONAL PLANE FLOWS







source (or sink), the complex potential of which is

  • source (or sink), the complex potential of which is
