  2. Washout (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Washout_(aeronautics)

    (This can be described as aerodynamic wash-in.) Winglets also promote a greater bending moment at the wing root, possibly necessitating a heavier wing structure. Installation of winglets may necessitate greater aerodynamic washout in order to provide the required resistance to spinning, or to optimise the spanwise lift distribution.

  3. Spoiler (car) - Wikipedia

    en.wikipedia.org/wiki/Spoiler_(car)

    Spoilers and wings on a vehicle have little effect at low speeds as improper designs may create undesirable responses and lower stability or efficiency for the car at high speeds. [ 3 ] Since "spoiler" is a term describing an application, the operation of a spoiler varies depending on the particular effect it is trying to spoil.

  4. Automotive aerodynamics - Wikipedia

    en.wikipedia.org/wiki/Automotive_aerodynamics

    Automotive aerodynamics is the study of the aerodynamics of road vehicles. Its main goals are reducing drag and wind noise, minimizing noise emission , and preventing undesired lift forces and other causes of aerodynamic instability at high speeds.

    Nonplanar wings: results for the optimal aerodynamic efficiency ratio ε. The parameter ε is the optimal aerodynamic efficiency ratio [25] and represents the ratio between the aerodynamic efficiency of a given non-planar wing and the corresponding efficiency of a reference classical cantilevered wing with the same wing span and total lift ...

    Aerodynamics – is the study of the motion of air, particularly with respect to its interaction with a solid object, such as an airplane wing. Aerodynamics is a sub-field of gas dynamics, which in turn is a sub-field of fluid dynamics. Many aspects and principles of aerodynamics theory are common to these three fields.

  7. Stall (fluid dynamics) - Wikipedia

    en.wikipedia.org/wiki/Stall_(fluid_dynamics)

    The position of a swept wing along the fuselage has to be such that the lift from the wing root, well forward of the aircraft center of gravity (c.g.), must be balanced by the wing tip, well aft of the c.g. [68] If the tip stalls first the balance of the aircraft is upset causing dangerous nose pitch up. Swept wings have to incorporate features ...

  8. Downwash - Wikipedia

    en.wikipedia.org/wiki/Downwash

    The effect of downwash from a hovering Sikorsky Seahawk is clearly visible on the surface of water below.. In aeronautics, downwash is the change in direction of air deflected by the aerodynamic action of an airfoil, wing, or helicopter rotor blade in motion, as part of the process of producing lift. [1]

  9. Wingtip vortices - Wikipedia

    en.wikipedia.org/wiki/Wingtip_vortices

    Wingtip vortices are circular patterns of rotating air left behind a wing as it generates lift. [1]: 5.14 The name is a misnomer because the cores of the vortices are slightly inboard of the wing tips. [2]: 369 Wingtip vortices are sometimes named trailing or lift-induced vortices because they also occur at points other than at the wing tips.
