High-Lift Design for a Forward Swept Natural Laminar Flow Wing

Autor(en): D. Keller
Zusammenfassung: The scope of the paper is to present the results of a RANS based aerodynamic high-lift design for a natural laminar flow wing with negative sweep. The chosen high-lift system consists of a Krueger leading edge flap with shielding function and a fixed-vane trailing edge flap. The design was first optimized in two main wing sections and then verified by 3D RANS siumlations of a wing-body model. Finally, engines were added to the geometric model in order to estimate the high-lift performance of the landing configuration. With a maximum lift coefficient of CL = 2:85 for the wing-body model with engine, the target from the preliminary aircraft design was reached. Further potential for improvement was found in the optimization strategy and the shape of the fuselage-wing junction.
