What is Slot *** aileron control?
A leading edge slot is a fixed (non-closing) gap behind the wing’s leading edge. Air from below the wing can accelerate through the slot towards the low pressure region above the wing, and exit from the slot moving parallel to the upper wing surface. This high-speed flow then mixes with the boundary layer attached to the upper surface and delays boundary layer separation from the upper surface. (this seperation of air is what causes the wing to stall at the critical angle of attack) Slots naturally exact a penalty on the aircraft in which they are used. This is because they contribute to drag compared to an unslotted wing.[7] The extra drag at low speed is acceptable because of the beneficial reduction in stall speed and improvement in handling characteristics, but at higher speeds the extra drag contributed by slots is a significant disadvantage because it reduces cruising speed and increases fuel consumption per unit distance flown. One way to reduce the cruise drag of slots is to ma
