The drag of airfoils has long been determined from measurements in the wake behind the airfoil. The well-known formula of Squire and Young can be used to transfer the measured data to infinity downstream of the airfoil, where an exact relation to the

The design case of an airfoil with distributed suction specifies, together with the suction compartments and the suction pressure, the porosity of the surface. To find the porosity for the design case and to evaluate the off-design cases, it is neces

The induced lift is defined as the lift due to the velocities that the lifting vortices induce on themselves. This lift does not increase the induced drag. This has the same effect as decreasing the induced drag without changing the lift. A simple me

The boundary layer properties depend only on the potential flow velocity distribution V(x) and the Reynolds number. Details will be described in Chapter 4. Boundary layer theory determines in many cases how V(x) must look in order to provide good bou

In this chapter, an airfoil shape is supposed to be given, for example, by an empirical mathematical function as for the NACA four digit airfoils (See [4]) or by a set of coordinates. The airfoil is subjected to an infinite parallel flow of velocity

Before the boundary layer flow is discussed, some remarks should be made about the nondimensional variables in the formulas and the units to be used. In mechanics, a system of three units is normally used, like meters, kilograms, and seconds or inche
