“…The experimental data presented and discussed in [23,24] show that extended regions of laminar flow occur on multi-element wings at high-lift conditions. On the B737-100, the entire slat (except for the cove) experienced laminar flow over a wide angle-of-attack range for all flap settings.…”

“…Flight experiments on NASA Langley's TSRV (B737-100) airplane were conducted to document flow characteristics for further understanding of high-lift flows [23][24][25][26][27]. The results of these flight experiments provide a good example of the complexity of the flow about threedimensional multi-element high-lift systems and the diversity of the transitional mechanisms.…”

“…Phase II involved surface pressure measurements and flow visualization across the full chord in the same region of the wing [25,26]. Phase III involved not only surface and skin-friction measurements but also boundary-layer profiles, boundary-layer states using hot films, and aeroelastic deformations using an optical system across the full chord near the mid-span station [27,23,24].

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
