It was solved in a paper published in [] by 1. von Neumann, who established the existence of a lifting in this case. In subsequent papers J. von Neumann and M. H. Stone [], and later on 1. Dieudonne [22], discussed various algebraic aspects and generalizations of the problem.

The lifting line theory is presented in Section , Numerical analysis of the wing and Section , The lift-induced drag coefficient: CDi. The Oswald span efficiency can be calculated using the method shown in Section , Computer code: Prandtl’s lifting line method.

  The "Skipping Stone" theory is based on the idea of air molecules hitting the underside of a wing as it moves through the air, and that lift is the reaction force of the impact. This theory completely overlooks the air molecules above the wing and makes the big assumption that it is only the underside of the wing that produces the lift, an idea that is known to be extremely inaccurate. Lift coefficient is illustrated in Fig. for an airfoil, i.e., a two-dimensional (infinite-span) wing. Considering first the full curve (a), which is for a moderately thick (13%) section of zero camber, it is seen to consist of a straight line passing through the origin, curving over at the higher values of C L, reaching a maximum value of C L max at an incidence of α s, known as the. The Circulation Theory of Lift. This is the oldest and most complex theory of lift. It explains how the difference in air speed over and under the wing results from a net “circulation” of air. Above the wing, the circulatory flow adds to the overall speed of the air; below the wing, it subtracts. Progression of literary theory in recent years has led theorists to expand the concept of an author as culture, implying that the text is a product of culture, and culture a product of text.

  Upwash and downwash are really results of this. Circulation and lifting line theory are more mathematical ways of estimating lift. Newton's laws apply too, but they, at least his second law, really deals with the change in momentum the wing causes in the air. The change in momentum of the air will equal the lift. No single theory EXPLAINS lift. Starting from a basic knowledge of mathematics and mechanics gained in standard foundation classes, Theory of Lift: Introductory Computational Aerodynamics in MATLAB/Octave takes the reader conceptually through from the fundamental mechanics of lift to the stage of actually being able to make practical calculations and predictions of the coefficient of lift for realistic wing profile and.

The results of this research are presented in the first theoretical part of the thesis. Then to verify the validity of the theory the practice work was accomplished.
