Record 1 2014-12-12

English

Subject field(s)
  • Aircraft Airframe
DEF

A streamlined fairing between wing and fuselage which serves to smooth out airflow and to diminish interference drag.

French

Domaine(s)
  • Cellule d'aéronefs

Carénage placé à la jonction de l'aile et du fuselage pour améliorer l'écoulement de l'air.

OBS

raccordement d'aile : L'emploi de ce terme est recommandé par le Ministère de la défense de la France.

Record 2 2010-10-27

English

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

A flap that can be extended on an aircraft to increase drag and reduce the speed of descent.

CONT

... dive flaps or dive brakes... serve to slow an aircraft in flight. These brakes are used when descending at a steep angle or when approaching the runway for a landing. The brakes themselves are manufactured in many shapes, and their location depends on the design of the aircraft and the purpose of the brakes. The brake panels may be located on certain parts of the fuselage or on the wing surfaces. Brakes on the fuselage are small panels that can be extended into the smooth airflow to create turbulence and drag. Wing-type brakes may be multiple-finger channels extending above and below the wing surfaces to break up smooth airflow. Usually speed brakes are controlled by electrical switches and actuated by hydraulic pressure.

OBS

Used on dive bombers and sailplanes.

French

Domaine(s)
  • Cellule d'aéronefs
  • Manœuvres d'aéronefs
DEF

Volet qui, en position sortie, augmente la traînée de l'avion et réduit la vitesse en descente.

CONT

Vol sur T-33 [...] Une autre amélioration était les «Dive brakes» (freins de piqué [...]), deux plaques métalliques qui sortaient sous le fuselage, presque perpendiculairement à l'écoulement de l'air, lorsque le pilote appuyait sur un poussoir situé sur la manette des gaz. Pour se ralentir, c'était très efficace et nécessaire car ces avions ne pouvaient pas passer la vitesse du son mais, en piqué, atteignaient très vite leur Mach critique [...] à partir duquel l'avion commençait à vibrer et à tressauter comme un cheval sauvage [...]

Record 4 2007-04-12

English

Subject field(s)
  • Aircraft Propulsion Systems
CONT

The Heinkel HeS 011 was an advanced World War II jet engine built by Heinkel-Hirth. It featured a then-unique compressor arrangement, combining a three-stage axial compressor with a "diagonal" stage similar to a centrifugal compressor, along with a low-compression impeller in the intake to smooth out airflow.

Record 5 2004-09-01

English

Subject field(s)
  • Sports Equipment and Accessories
  • Underwater Diving (Sports)
CONT

The common mouthpiece is a thin flange which fits outside the teeth but inside the lips. Two protusions inside the mouthpiece are held by the teeth. This keeps the teeth apart and the mouthpiece secure.

CONT

The deflector vane found in the ALPHA7 diverts airflow from the valve directly to the mouthpiece, producing smooth ventury-assisted inhalation.

OBS

mouthpiece: Terminology officially approved by the Naval Terminology Standardization Committee.

French

Domaine(s)
  • Équipement et accessoires de sport
  • Plongée sous-marine (Sports)
DEF

Partie d'un appareil de protection respiratoire qu'on introduit dans la bouche et qui est reliée à un dispositif d'épuration d'air ou à une source de gaz respirable, ou les deux.

OBS

embout buccal : Terminologie adoptée par le Comité de normalisation de la terminologie navale.

Record 6 1999-06-03

English

Subject field(s)
  • Flight Controls (Aeroindustry)
DEF

auxiliary airfoil : A secondary airfoil such as a slat, flap, or tab, that supplements or aids flight in some manner, as by creating an additional force or by providing a smooth airflow.

OBS

secondary control surface; auxiliary control surface: The flight control surfaces are divided differently depending upon the sources consulted. Some include two groups: 1. primary or main group 2. secondary or auxiliary group (e.g. flaps, spoilers, leading edge devices, trim tab, balance tab, servo tab) and others, three groups: 1. primary group 2. secondary group (e.g. trim tab, spring tab) 3. auxiliary group (e.g. wing flap, spoiler, speed brakes, slats and slots, leading edge flaps). The CUTA maintenance considers secondary control surface and auxiliary control surface as synonyms.

OBS

auxiliary control surface: term standardized by ISO.

French

Domaine(s)
  • Commandes de vol (Constructions aéronautiques)
CONT

Les gouvernes sont les surfaces mobiles de la cellule qui par leur action aérodynamique, permettent de faire varier l'assiette et la configuration de l'avion. On distingue les gouvernes primaires [...] et les gouvernes secondaires qui sont les tabs, les volets de bord d'attaque et de bord de fuite, les becs d'aile à fente et les déporteurs.

OBS

Le terme «gouverne secondaire» a été uniformisé par le CUTA maintenance.

OBS

gouverne auxiliaire : terme normalisé par l'ISO.

Record 7 1982-06-07

English

Subject field(s)
  • Aeroindustry
CONT

The only aerodynamic modifications of the Mirage 2000 are the thinning of the lower segment of the intake lips, the addition of a wing-root extension to smooth airflow immediately aft of the wing, and the reduction in height and aspect ratio of the fin, without changing its area.

French

Domaine(s)
  • Constructions aéronautiques
CONT

Les seules modifications aérodynamiques qui ont été apportées au Mirage 2000 dans le but d'améliorer les performances en vol supersonique, sont un amincissement de la lèvre inférieure de l'entrée d'air, l'installation d'un karman de voilure pour améliorer l'écoulement de l'air juste en arrière de l'aile, et une diminution de la hauteur et de la finesse de la dérive.
