The geometry of wings includes rectangular wings, trapezoidal wings, and swept wings. One of the most critical parts of an airplane is, obviously, the wings. The geometry and airfoil profiles are mainly studied in this paper. The wings primarily create the lift to overcome the aircraft’s weight. However, they also have movable surfaces, such as ailerons, flaps, spoilers, etc., to develop additional aerodynamic forces to control the aircraft during its flight. Wings are geometrically defined in terms of their span, planform, twist, and cross-section (i.e., airfoil section shape or profile shape). The shape of a wing is engineered to give good aerodynamic efficiency in lift production for the minimum amount of drag, i.e., the maximization of the lift-to-drag ratio, which is one fundamental goal in aerodynamic design. However, there will always be other aerodynamic requirements that will factor into the wing shape design, including its low-speed flight and stalling characteristics. The wing of an airplane is not only a masterful piece of engineering but an item of beauty. The paper presents both the aerodynamic design and optimization of the NLF wing and the high-lift configuration considering the mutual effects of both flap devices.

The wing, in this case, sports a blended winglet (the upturned part at the tip of the wing) to help reduce drag. It is a very thin and low cambered airfoil, characterized by a complex morphology near the leading edge (X/c<30, where X is the distance from. In the present work, the aerodynamic shape design of an advanced high-lift system for a natural laminar flow (NLF) wing, based on the combination of a morphing droop nose and a single slot trailing edge flap, is presented.
