This chapter exploits the solutions of the thin foil boundary value problems to define and quantify important lifting foil properties. Besides the lift force and lift coefficient, it is useful to know the center of effort for the lift force. It is important for balancing control surfaces like rudders or stabilizers and also affects the spindle moment of the blades in a controllable pitch propeller. The ideal angle of attack is important because it provides shock free entry for the leading edge. Ideally, a foil will operate at its ideal angle of attack to delay cavitation inception. In the practical design of foil sections, engineers start with a desired pressure distribution rather than an equation for the mean line. In a real fluid, the pressure would not rise that far and there is no infinitely thin plate which could support such a high pressure difference.
