  2. Aeroelasticity - Wikipedia

    en.wikipedia.org/wiki/Aeroelasticity

    Equations for divergence of a simple beam Divergence can be understood as a simple property of the differential equation(s) governing the wing deflection. For example, modelling the airplane wing as an isotropic Euler–Bernoulli beam, the uncoupled torsional equation of motion is = ′,

  3. Flight control surfaces - Wikipedia

    en.wikipedia.org/wiki/Flight_control_surfaces

    A raised aileron reduces lift on that wing and a lowered one increases lift, so moving the aileron control in this way causes the left wing to drop and the right wing to rise. This causes the aircraft to roll to the left and begin to turn to the left. Centering the control returns the ailerons to the neutral position, maintaining the bank angle ...

  4. Lifting-line theory - Wikipedia

    en.wikipedia.org/wiki/Lifting-line_theory

    Lifting line theory supposes wings that are long and thin with negligible fuselage, akin to a thin bar (the eponymous "lifting line") of span 2s driven through the fluid. . From the Kutta–Joukowski theorem, the lift L(y) on a 2-dimensional segment of the wing at distance y from the fuselage is proportional to the circulation Γ(y) about the bar a

  5. Aileron - Wikipedia

    en.wikipedia.org/wiki/Aileron

    The down moving aileron also adds energy to the boundary layer. The edge of the aileron directs air flow from the underside of the wing to the upper surface of the aileron, thus creating a lifting force added to the lift of the wing. This reduces the needed deflection of the aileron.

  6. Stability derivatives - Wikipedia

    en.wikipedia.org/wiki/Stability_derivatives

    Equations of motion are used to analyze these changes and oscillations. Stability and control derivatives are used to linearize (simplify) these equations of motion so the stability of the vehicle can be more readily analyzed. Stability and control derivatives change as flight conditions change.

  7. Camber (aerodynamics) - Wikipedia

    en.wikipedia.org/wiki/Camber_(aerodynamics)

    Camber is a complex property that can be more fully characterized by an airfoil's camber line, the curve Z(x) that is halfway between the upper and lower surfaces, and thickness function T(x), which describes the thickness of the airfoils at any given point. The upper and lower surfaces can be defined as follows:

  8. Aileron roll - Wikipedia

    en.wikipedia.org/wiki/Aileron_roll

    Note the aileron deflection on the right wing. Diagram of how an aileron roll is performed in relation to other common rolls. The aileron roll is an aerobatic maneuver in which an aircraft does a full 360° revolution about its longitudinal axis. When executed properly, there is no appreciable change in altitude and the aircraft exits the ...

  9. Washout (aeronautics) - Wikipedia

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

    The wing is designed so that the angle of incidence is greater at the wing roots and decreases across the span, becoming lowest at the wing tip. This is usually to ensure that at stall speed the wing root stalls before the wing tips, providing the aircraft with continued aileron control and some resistance to spinning.
