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.
A leading-edge slat is an aerodynamic surface running spanwise just ahead of the wing leading edge. It creates a leading edge slot between the slat and wing which directs air over the wing surface, helping to maintain smooth airflow at low speeds and high angles of attack.
Similar, but retractable, leading-edge devices are called slats. [4] When the slat opens, it creates a slot between the slat and the remainder of the wing; retracted, the drag is reduced. A fixed leading-edge slot can increase the maximum lift coefficient of an airfoil section by 40%. In conjunction with a slat, the increase in maximum lift ...
Slats, also known as leading edge devices, are extensions to the front of a wing for lift augmentation, and are intended to reduce the stalling speed by altering the airflow over the wing. Slats may be fixed or retractable - fixed slats (e.g. as on the Fieseler Fi 156 Storch ) give excellent slow speed and STOL capabilities, but compromise ...
Another common high-lift device is the slat, a small aerofoil shaped device attached just in front of the wing leading edge. The slat re-directs the airflow at the front of the wing, allowing it to flow more smoothly over the upper surface when at a high angle of attack. This allows the wing to be operated effectively at the higher angles ...
Slat and slot: a leading-edge slat is a small aerofoil extending in front of the main leading edge. The spanwise gap behind it forms a leading-edge slot. Air flowing up through the slot is deflected backwards by the slat to flow over the wing, allowing the aircraft to fly at lower air speeds without flow separation or stalling.
Krueger flaps deployed from the leading edge of a Boeing 747 (top left and right in photo). Krueger flaps, or Krüger flaps, are lift enhancement devices that may be fitted to the leading edge of an aircraft wing. Unlike slats or droop flaps, the main wing upper surface and its leading edge is not changed. Instead, a portion of the lower wing ...
Late-series aircraft equipped with leading-edge slats to improve maneuverability at the expense of top speed under the Agile Eagle program. Starting with Block 53, aircraft added AGM-65 Maverick capability and smokeless J79-GE-17C or -17E engines. First flight 1 August 1965. The most numerous Phantom variant; 1,370 built. F-4E Kurnass 2000
