  2. Stall (fluid dynamics) - Wikipedia

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

    In generic terms, a stick pusher is known as a stall identification device or stall identification system. [73] A stick shaker is a mechanical device that shakes the pilot's controls to warn of the onset of stall. A stall warning is an electronic or mechanical device that sounds an audible warning as the stall speed is approached. The majority ...

  3. Dynamic stall on helicopter rotors - Wikipedia

    en.wikipedia.org/wiki/Dynamic_stall_on...

    The development process of dynamic stall on 2D airfoil can be summarized in several stages: [8] [9] Stage 1: the AoA exceeds the static stall angle but the flow separation is delayed due to the reduction of adverse pressure gradients produced by the kinematics of pitch rate.

  4. Leading-edge slot - Wikipedia

    en.wikipedia.org/wiki/Leading-edge_slot

    A leading-edge slot is a fixed aerodynamic feature of the wing of some aircraft to reduce the stall speed and promote good low-speed handling qualities. A leading-edge slot is a spanwise gap in each wing, allowing air to flow from below the wing to its upper surface.

  5. Aircraft design process - Wikipedia

    en.wikipedia.org/wiki/Aircraft_design_process

    Advanced Supersonic Transport (AST) model in wind tunnel. The aircraft design process is a loosely defined method used to balance many competing and demanding requirements to produce an aircraft that is strong, lightweight, economical and can carry an adequate payload while being sufficiently reliable to safely fly for the design life of the aircraft.

  6. Stall strips - Wikipedia

    en.wikipedia.org/wiki/Stall_strips

    One of a pair of stall strips installed on an American Aviation AA-1 Yankee during manufacture. A stall strip is a small component fixed to the leading edge of the wing of an airplane to modify its aerodynamic characteristics. [1] These stall strips may be necessary for the airplane to comply with type certification requirements.

  7. Leading-edge slat - Wikipedia

    en.wikipedia.org/wiki/Leading-edge_slat

    A slat is an aerodynamic surface on the leading edge of the wing of a fixed-wing aircraft.When retracted, the slat lies flush with the rest of the wing. A slat is deployed by sliding forward, opening a slot between the wing and the slat.

  8. Ground effect (aerodynamics) - Wikipedia

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

    [25] [26] Loss of control may occur if one wing tip stalls in ground effect. During certification testing of the Gulfstream G650 business jet the test aircraft rotated to an angle beyond the predicted IGE stalling angle. The over-rotation caused one wing-tip to stall and an uncommanded roll, which overpowered the lateral controls, leading to ...

    en.wikipedia.org/wiki/Aircraft_flight_dynamics

    The wind frame is a convenient frame to express the aerodynamic forces and moments acting on an aircraft. In particular, the net aerodynamic force can be divided into components along the wind frame axes, with the drag force in the −x w direction and the lift force in the −z w direction.
