The trailing edge of an aerodynamic surface such as a wing is its rear edge, where the airflow separated by the leading edge rejoins. Essential flight control surfaces are attached here to control the direction of the departing air flow, and exert a controlling force on the aircraft.

Accordingly, what is leading and trailing edge?

Leading-edge: inductive loads (e.g. magnetic low voltage transformers), resistive loads (e.g. incandescent). Trailing-edge: capacitive loads (e.g. electronic low voltage transformers, LED drivers), resistive loads (e.g. incandescent).

Also Know, what are the four main types of flaps? There are four basic types of flaps: plain, split, Fowler and slotted. The plain flap is simply a hinged portion of the trailing edge. Split type flaps are hinged at the bottom of the wing and create much more drag than plain flaps.

Correspondingly, what is the leading edge of a plane?

The leading edge is the part of the wing that first contacts the air; alternatively it is the foremost edge of an airfoil section.

What is the difference between leading and trailing edge dimmer?

Leading edge dimming cuts of the front edge of each waves' half cycle. Conversely trailing edge dimming cuts out the second half of each waves' half cycle. Trailing edge dimmers are now the more popular of the two types.

What does trailing edge dimmable mean?

Trailing Edge Dimming (electronic dimming) utilizes a current that is turned off as the AC waveform ends, right before it crosses zero. This type of dimming is typically used with electronic drivers, and does not result in a rush of voltage (and in turn, a rush of current) to the light source.

Do I need a leading edge or trailing edge dimmer?

Leading edge dimmers are suitable for inductive load, for example magnetic low voltage transformers; and resistive loads like incandescent light bulbs. Trailing edge dimmers are suitable for capacitive loads like electric low voltage transformers and LED drivers as well as resistive loads like incandescent bulbs.

What is rising edge and falling edge?

A rising edge (or positive edge) is the low-to-high transition. A falling edge (or negative edge) is the high-to-low transition.

What is phase dimmable?

Phase control is a dimming technique based on the electric wire that is often used for halogen and incandescent lamps. It “clips” part of the sine wave of the alternating current to dim the light.

What do leading edge slats do?


The leading edge slats allow the aircraft to fly at a high angle of attack (lower speed) by accelerating the air between the slat and the wing (venturi effect).

What is the trailing edge of a wing?

The trailing edge of an aerodynamic surface such as a wing is its rear edge, where the airflow separated by the leading edge rejoins. Essential flight control surfaces are attached here to control the direction of the departing air flow, and exert a controlling force on the aircraft.

How do leading edge dimmers work?

Leading-edge dimmer switches are cheaper and simpler than trailing-edge, and were used originally to dim incandescent and halogen bulbs or wirewound magnetic transformers. They use a 'TRIAC' (Triode for Alternating Current) switch to control power, and are sometimes called TRIAC dimmers.

Is it leading edge or bleeding edge?

Leading edge is a term for being in the forefront of a field. The term probably comes from the leading edge of an airfoil or similar body in aerodynamics. Bleeding edge is a play on leading edge, referring to the high risk of leading edge technology failing or encountering problems.

What is leading edge suction?

(C) Leading-edge suction occurs when pitching movements of the airfoil shift the stagnation point and positive pressure to one side, allowing negative pressure to act more anteriorly on the opposite side (11,12,(14)(15) (16) ).

How does a slat work?


Slats perform the same function as flaps (that is, they temporarily alter the shape of the wing to increase lift), but they're attached to the front of the wing instead of the rear. Pilots also deploy them on takeoff and landing. Pilots have to do more than guide a plane through takeoff and landing though.

What is leading edge fall protection?

The leading edge fall protection system is designed to control the unique fall hazards posed by leading edge work. The leading edge fall protection system provides an anchor at seven feet above the deck, creating a smaller fall distance than conventional methods, which are anchored below shoulder level.

What is the difference between leading edge flaps and slats?

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.

How do slats increase lift?

The flaps and slats move along metal tracks built into the wings. Moving the flaps aft (toward the tail) and the slats forward increases the wing area. Pivoting the leading edge of the slat and the trailing edge of the flap downward increases the effective camber of the airfoil, which increases the lift.

What is the difference between cutting edge and bleeding edge?

The tip of a knife is known as the bleeding edge. The tip pierces and breaks through. The cutting edge is the part of the knife that does most of the work.

What is a slat track?


The part on the leading edge is called a slat, while the part on the trailing edge is called a flap. The flaps and slats move along metal tracks built into the wings. Moving the flaps aft (toward the tail) and the slats forward increases the wing area.

What are leading edge devices?

Leading edge devices are located at the leading edge of the wing and can be deployed during different flight phases (take off, landing and cruise) in order to improve the aerodynamic performances of the the aircraft.

What is a slat on a plane?

Slats are aerodynamic surfaces on the leading edge of the wings of fixed-wing aircraft which, when deployed, allow the wing to operate at a higher angle of attack.
