21 Ιαν 2023 · This slide gives technical definitions of a wing’s geometry, which is one of the chief factors affecting airplane lift and drag. The terminology used here is used throughout the airplane industry today and was mostly known to the Wright brothers in 1900.
Wings are geometrically defined in terms of their span (distance from wing tip to wing tip), planform (their shape in outline looking down on the wing from above), twist (pitch angle) distribution, and cross-section (i.e., airfoil section shape or profile shape).
This slide gives technical definitions of a wing's geometry, which is one of the chief factors affecting airplane lift and drag. The terminology is used throughout the airplane industry and is also found in the FoilSim program developed here at NASA Glenn.
Appreciate the historical evolution of airfoil sections for aircraft applications. Identify and explain the significance of the critical geometric parameters that define the shape of an airfoil. Know how to construct a NACA airfoil profile geometrically using a camberline shape, thickness envelope, and nose radius.
26 Ιουν 2024 · Figure 3.20: Wing geometry. In order to characterize the geometry and nomenclature of a typical commercial aircraft wing, the following wing elements are illustrated in Figure 3.20: Wingspan b b. Chords: root chord cr c r and tip chord ct c t.
Since the wing geometry and its features are influencing all other aircraft components, we begin the detail design process by wing design. The primary function of the wing is to generate sufficient lift force or simply lift (L). However, the wing has two other productions, namely drag force or drag (D) and nose-down pitching moment (M).
28 Σεπ 2022 · The Wing Plotting Tool allows you to sketch a wing planform by defining a valid combination of the critical wing geometric properties: Wing Area, Wing Span, Aspect Ratio, Taper Ratio, Root Chord, Tip Chord, and Sweep angle (quarter chord).
