  2. 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 ...

  3. Thickness-to-chord ratio - Wikipedia

    en.wikipedia.org/wiki/Thickness-to-chord_ratio

    The natural outcome of this requirement is a wing design that is thin and wide, which has a low thickness-to-chord ratio. At lower speeds, undesirable parasitic drag is largely a function of the total surface area , which suggests using a wing with minimum chord, leading to the high aspect ratios seen on light aircraft and regional airliners .

  4. Aircraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Aircraft_flight_dynamics

    It is common practice to derive a fourth order characteristic equation to describe the longitudinal motion, and then factorize it approximately into a high frequency mode and a low frequency mode. The approach adopted here is using qualitative knowledge of aircraft behavior to simplify the equations from the outset, reaching the result by a ...

  5. Aileron - Wikipedia

    en.wikipedia.org/wiki/Aileron

    Pairs of ailerons are typically interconnected so that when one is moved downward, the other is moved upward: the down-going aileron increases the lift on its wing while the up-going aileron reduces the lift on its wing, producing a rolling (also called 'banking') moment about the aircraft's longitudinal axis (which extends from the nose to the ...

  6. 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 = ′,

  7. 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 ...

    An American Airlines flight departing New York's LaGuardia Airport on Thursday evening had to divert to nearby John F. Kennedy International shortly after takeoff after a reported bird strike ...

  9. Aspect ratio (aeronautics) - Wikipedia

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

    Also, longer wings may have some torsion for a given load, and in some applications this torsion is undesirable (e.g. if the warped wing interferes with aileron effect). Maneuverability : a low aspect-ratio wing will have a higher roll angular acceleration than one with high aspect ratio, because a high aspect-ratio wing has a higher moment of ...
