Record 2 2010-04-16

English

Subject field(s)
  • Aircraft Airframe
  • Aircraft Maneuvers
DEF

A flap which, when deflected, opens a slot between itself and the main surface.

CONT

The slotted flap is like the Fowler flap in operation, but in appearance it is similar to the plain flap. This flap is equipped with either tracks and roller or hinges of a special design. During operation, the flap moves downward and rearward away from the position of the wing. The "slot" thus opened allows a flow of air over the upper surface of the flap. The effect is to streamline the airflow and to improve the efficiency of the flap.

OBS

slotted flap: term standardized by ISO.

DEF

Volet qui, en se braquant, dégage une fente entre son bord d'attaque et l'aile.

CONT

Le volet à fente [...] est une surface mobile ressemblant à une petite aile dont le point de rotation se trouve sous l'aile. Le braquage du volet ouvre une fente qui permet à l'air de passer de l'intrados vers l'extrados pour réaccélérer la couche limite et retarder ainsi le décollement des filets d'air sur le volet. Quand le rayon de rotation du volet est important, le volet recule en même temps qu'il se braque vers le bas (Dyn'aero MCR).

OBS

volet à fente : terme normalisé par l'ISO.

Record 3 2009-07-16

English

Subject field(s)
  • Aircraft Airframe
  • Aircraft Maneuvers
CONT

The use of flaps located on the trailing edge of an airplane wing to vary wing lift characteristics during various flight phases is well known. In the so-called single slotted flap arrangement, a wing flap is extended relative to the stationary wing of the aircraft so that a spanwise slot is formed between the trailing edge of the wing and the leading edge of the flap. This slot directs airflow from below the wing and the flap for subsequent discharge across the upper surface of the flap in the direction of and substantially parallel to the air normally flowing over the upper surface of the flap.

Record 4 1982-06-07

English

Subject field(s)
  • Aeroindustry
CONT

For added drag in the landing case, the trailing-edge portion of the inboard flap pivots further down on an offset hinge, opening a gap rather than a slot between itself and the main flap surface.

French

Domaine(s)
  • Constructions aéronautiques
CONT

Pour augmenter la traînée à l'atterrissage, la partie arrière du volet intérieur pivote davantage vers le bas grâce à une articulation excentrée, ce qui crée un espace plutôt qu'une fente entre cette section et la partie principale du volet.
