Book Description
A nonuniform transonic airfoil code is developed for applications in analysis, inverse design and direct optimization involving an airfoil immersed in propfan slipstream. Problems concerning the numerical stability, convergence, divergence and solution oscillations are discussed. The code is validated by comparing with some known results in incompressible flow. A parametric investigation indicates that the airfoil lift-drag ratio can be increased by decreasing the thickness ratio. A better performance can be achieved if the airfoil is located below the slipstream center. Airfoil characteristics designed by the inverse method and a direct optimization are compared. The airfoil designed with the method of direct optimization exhibits better characteristics and achieves a gain of 22 percent in lift-drag ratio with a reduction of 4 percent in thickness.

Book Description
This report describes the development of numerical techniques for predicting the flow over two-element airfoil configurations, such as airfoils with a slat or a flap, at transonic speeds and for designing such airfoil systems. The effort was divided in three phases. The first phase involved the development of a method to compute the inviscid flow over these configurations. In the second phase the inviscid code was coupled to a boundary layer calculation program in order to compute the loss in performance due to viscous effects. In the third phase an inverse design code that constructs the airfoil system corresponding to a desired pressure distribution was developed. (Author).
