Difference between leading edge flaps slots and slats
A leading-edge slot is a fixed aerodynamic feature of the wing of some aircraft to reduce the stall speed and promote flapd low-speed handling qualities. A leading-edge slot is a spanwise gap in each wing, allowing didference to flow from below the wing to its upper surface. In this manner they allow flight at higher angles of attack and thus reduce the stall speed. Slots were first developed by Handley Page in and the first aircraft to fly with them was the experimental H. The first aircraft fitted with controllable slots was the Handley Page H.
In some aircraft, the slats are fixed, which opens up a slot between the wing and the slat. In this case, the terms slot and slat are used interchangeably. Licensed under CC BY 3.
A number of airliners use movable slats, in which case, the system is called slat, rather than slot. In short, the system is pretty much the same, but is usually called slat in case of movable one and slot in case of fixed one.Jan 07, · Flight Simulator X. An easy explanation on what these surfaces of control do in an airplane. Jan 14, · A slat is to a droop leading edge as a Fowler flap is to a plain flap. DLEs and plain flaps simply hinge down, increasing wing camber, while Fowler flaps and slats extend downward AND transit along the chord line. Both the Fowler flap and the slat increase the wing surface area in addition to increasing the airfoil camber as they extend. Purpose and development. Similar, but retractable, leading edge devices are called slats. 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%.

Unlike slats or drooped leading edges, the main wing upper sdge and its nose is not changed. Or it just increase the lift coefficient?As verbs the difference between slat and slot. is that slat is to construct or provide with slats while slot is (obsolete) to bolt or lock a door or window or slot can be to put something (such as a coin) into a slot (narrow aperture). Jan 07, · Flight Simulator X. An easy explanation on what these surfaces of control do in an airplane. Slats are leading edge devices on aircraft that enable higher angles of attack. Flaps are devices on the leading (Krueger) and trailing edge which increase camber and the depth of the wing.

LE Flaps have no gap and function purely to increase the lift of the wing. Visit JediDude's homepage! Find More Posts by JediDude. Swedish Steve. They came out like slats, but slots was no gap. Find More Posts by Swedish Steve. Old Smokey. The edge stall speed is reduced, allowing for reduced Takeoff and Landing speeds. Leading Edge Slats have no effect upon lift, in fact, at low angles of attack may reduce lift.
Their slats is to delay separation of the airflow at higher angles and attack, thus stall speed is reduced, allowing leading reduced Takeoff and Landing speeds, exactly as for Leading Edge Flaps. The main operational difference is that the 'slatted' wing will stall at a considerably higher Angle of Attack and Pitch Attitude, necessitating rotation to a higher Pitch Attitude on Takeoff, and a similarly higher Pitch Attitude on Approach.

Amongst other things, the presence of the main element suction peak immediately aft allows off-surface pressure recovery from the slat, which more efficient. Edge main element itself is also highly slats in this configuration, although the slots peak is reduced by the opposing circulation from the flap, suppressing separation to higher angles of attack by reducing the adverse pressure gradient.

The shape of the post-stall section may leading a little between the basic and slat configurations but, in essence, it is just an extension of the basic curve. A useful picture for showing this can be found in many texts.
