Record 1 2010-05-18

English

Subject field(s)
  • Aeroindustry
CONT

Divergence occurs when a lifting surface deflects under aerodynamic load so as to increase the applied load, or move the load so that the twisting effect on the structure is increased.

OBS

aerodynamic load: term officially approved by the International Civil Aviation Organization (ICAO).

PHR

High, negative airload.

Key term(s)
  • air load
  • air-load

French

Domaine(s)
  • Constructions aéronautiques
CONT

On peut dire que cette méthode figure parmi les meilleures pour le calcul de performances des hélices (traction, puissance, rendement), celui de la répartition de charge aérodynamique sur les pales, ainsi que celui du souffle à l'aval de l'hélice.

OBS

charge aérodynamique : terme uniformisé par l'Organisation de l'aviation civile internationale (OACI) et par les Comités d'uniformisation de la terminologie aéronautique (CUTA) - Opérations aériennes et Maintenance.

PHR

Charge aérodynamique élevée, négative.

Spanish

Campo(s) temático(s)

OBS

carga aerodinámica: término aceptado oficialmente por la Organización de Aviación Civil Internacional (OACI).

Record 2 2009-06-12

English

Subject field(s)
  • Aircraft Airframe
DEF

A wing that is not linked to the fuselage by means of a mast or bracing wire.

CONT

The most common current wing design is the cantilever. A single large beam, called the main spar, runs through the wing, typically nearer the leading edge at about 25 percent of the total chord. In flight, the wings generate lift, and the wing spars are designed to carry this load through the fuselage to the other wing. To resist fore and aft movement, the wing will usually be fitted with a second smaller drag-spar nearer the trailing edge, tied to the main spar with structural elements or a stressed skin. The wing must also resist twisting forces, done either by a monocoque "D" tube structure forming the leading edge, or by the aforementioned linking two spars in some form of box beam or lattice girder structure.

French

Domaine(s)
  • Cellule d'aéronefs
DEF

Aile qui n'est pas reliée au fuselage par un mât ou un hauban.

CONT

En aéronautique, on appelle une «aile cantilever», un système de voilure développé vers le milieu des années 1910 selon un principe permettant d'éviter les haubans (générateurs de traînée perturbatrice) auxquels la voilure des premiers avions était suspendue. L'un des premiers à avoir mis au point ce principe était Levavasseur sur son avion Antoinette monobloc.

OBS

La voilure désigne l'ensemble des ailes. Chaque aile prise individuellement est appelée demi-voilure.

OBS

aile cantilever; aile en porte-à-faux : termes uniformisés par le Comité d'uniformisation de la terminologie aéronautique (CUTA) - Maintenance.

Key term(s)
  • aile en porte à faux
  • demi-voilure en porte-à-faux
  • demi voilure en porte à faux
  • demi voilure en porte-à-faux

Subject field(s)
  • Metrology and Units of Measure
  • General Mechanics (Physics)
  • Bodywork and Framework (Motor Vehicles)
DEF

A strength measurement that combines the Yield strength of the material and the load carrying capacity based on the material size and shape.

CONT

Resisting bending moment (RBM) [is] a calculation used to compare frames of different section modulus and of different material. It is the product of the section modulus times the yield strength of the frame material. The formula is expressed as: RBM = Section Modulus x Yield Strength.

CONT

The mainframe of a heavy or medium-duty truck or tractor consists of a pair of C-section rails running the vehicle's length... joined by C-, T-, L-or hat-section crossmembers.... "Resisting bending moment, "or RBM [is] measured in inch-pounds. RBM describes the frame's ability to withstand twisting forces as well as its carrying ability... A road tractor's frame might be built with an RBM of 1. 3 million to 1. 6 million inch-pounds, while a quad-rear-axle dump truck's frame might have an RBM of 3 million inch-pounds. Yes, those are torque values, because torque is what's applied to the frame as the vehicle rocks and rolls its way over a jobsite or roadway, and its load pulls and pushes on the frame.

CONT

Avec trois options selon la force des bâtis, les modèles de la classe 4-5 de GM permettent d'optimiser la capacité en poids et en charge supportée en vue d'usages spécifiques et ce, sans exiger de renfort. Les options incluent : . longerons de 6 mm d'épaisseur en acier d'une résistance de 50 000 lb/po² dans le cas des châssis d'autobus, procurant un moment de résistance à la flexion (MRF) de 356 000 lbf-po.

OBS

flexion : Mécan. Courbure d'une pièce longue (poutre, barre...) sous l'action de forces perpendiculaires à l'axe longitudinal et appliquées en des points où la pièce n'est pas soutenue. Flexion plane. Module de flexion. Résistance à la flexion.
