“…Rogers et al [47][48][49][50][51][52] have published a wide array of papers demonstrating the effectiveness of this method. Its drawback is that it is based on the incompressible equations and, hence, the important effect of Mach number on maximum lift coefficient cannot be evaluated.…”

High-lift systems have a major influence on the sizing, economics, and safety of most transport airplane configurations. The combination of complexity in flow physics, geometry, and system support and actuation has historically led to a lengthy and experiment intensive development process. However, during the recent past engineering design has changed significantly as a result of rapid developments in computational hardware and software. In aerodynamic design, computational methods are slowly superseding empirical methods and design engineers are spending more and more time applying computational tools instead of conducting physical experiments to design and analyze aircraft including their high-lift systems. The purpose of this paper is to review recent developments in aerodynamic design and analysis methods for multi-element high-lift systems on transport airplanes. Attention is also paid to the associated mechanical and cost problems since a multi-element high-lift system must be as simple and economical as possible while meeting the required aerodynamic performance levels. r

“…Aerodynamic performances of selected solutions and efficiency of present method In this study, the aerodynamic performances of the solutions selected from final samples (including baseline) were investigated because the EI value can be a criteria for the global optimum. 6) Considering L=D maximization, Optimum-1 was selected as an optimum configuration which achieved the highest L=D. The response surface discussed in 3.2 has two peaks, one is Optimum-1 and the other is the baseline.…”

In this paper, the design optimization procedure of a three-element wing setting is discussed. The positions of elements are determined using a response surface method based on the Kriging model. The Kriging model is updated based on expected improvement (EI) value maximization in the design space using a distributed genetic algorithm (DGA). Sample points for the Kriging model are evaluated using Reynolds Averaged Navier-Stokes simulation (RANS). The present method is applied successfully for the optimization, where the objective function is to maximize the lift-todrag ratio (L=D).
