CONT

When mechanical clearers are used, the yarn passes through a slot between two blades which can be adjusted according to the yarn count and the desired cleaning effect.

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.

  • Manœuvres d'aéronefs
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 2008-09-09

English

Subject field(s)
  • Aerodynamics and Theory of Gases
  • Wind Energy
DEF

The benefit derived from airflow through a gap between a slot or auxiliary airfoil and a wing or second airfoil.

OBS

The slot effect was first noticed on jib-rigged sailboats where the foresail directs flow over the mainsail, accentuating the mainsail' s performance.

French

Domaine(s)
  • Théorie des gaz et aérodynamique
  • Énergie éolienne
DEF

Accroissement du rendement lié au passage de l'air à travers l'interstice entre un bec ou profil auxiliaire et une aile ou profil secondaire.

OBS

L'effet de couloir a été remarqué pour la première fois sur les bateaux à voiles gréées, ou la misaine dirige le flux d'air directement sur la grand-voile, améliorant sa productivité.

Record 4 1998-04-21

English

Subject field(s)
  • Aircraft Propulsion Systems
CONT

The X-wing has emerged from the circulation controlled rotor(CCR) in which a hollow blade of roughly oval aerofoil section, that is, without a real lifting profile at all, can be made to lift effectively by blowing a layer of air through a slot and across the curved Coanda surface which forms the trailing-edge. While this in itself produces lift, the air jet can be so modulated as the rotor turns that it has the same effect as the cyclic pitch changing of the normal rotor. Finally, a further jet can be blown through a second slot near the leading-edge of the blade so that it restores the lost lift of the retreating blade. This fore-and-aft blowing is the key to the stopped-rotor X-wing.

Record 5 1996-10-11

English

Subject field(s)
  • Equipment (Chemistry)
DEF

[In flame spectroscopy], a burner in which fuel and oxidant are thoroughly mixed inside the burner housing before they leave the burner ports and enter the primary-combustion or inner zone of the flame. This type of burner usually produces an approximately laminar flame, and is commonly combined with a separate unit for nebulizing the sample.

CONT

The second type of burner, used in most commercial instruments, is the premix chamber burner, sometimes called the laminar-flow burner.... The fuel and support gases are mixed in a chamber before they enter the burner head(through a slot) where they combust. The sample solution is again aspirated through a capillary by the "Venturi effect" using the support gas for the aspiration. Large droplets of the sample condense and drain out of the chamber. The remaining fine droplets mix with the gases and enter the flame. As much as 90% of the droplets condense out, leaving only 10% to enter the flame.

French

Domaine(s)
  • Équipement (Chimie)
DEF

[En spectroscopie à flamme], un brûleur dans lequel le combustible et le comburant sont complètement mélangés à l'intérieur du brûleur avant de franchir son ou ses orifices de sortie et de pénétrer dans la zone de combustion primaire ou dans la zone interne de la flamme. Ce type de brûleur produit habituellement une flamme approximativement laminaire et est couramment associé à un dispositif distinct de nébulisation de l'échantillon.
