Record 3 2011-06-09

English

Subject field(s)
  • Helicopters (Military)
  • Types of Aircraft
DEF

A helicopter with an auxiliary propulsion system which provides thrust in excess of that which the rotor alone could produce, thereby permitting increased forward speeds; wings may or may not be provided to reduce the lift required from the rotor system. [Definition standardized by NATO.]

CONT

The rotor of the compound helicopter is powered for take-off; once cruising altitude is reached, the engine power is used to drive a propeller for forward thrust, and the rotor is allowed to freewheel and autorotate as do the blades of an autogiro. The aircraft usually has small wings to furnish lift in forward flight...

CONT

The Lockheed AH-56A Cheyenne ... represents a recent addition to the compound helicopter family ...

OBS

compound helicopter: term standardized by NATO.

A shaft from which power is available to drive accessory or other item.

CONT

The freewheel assembly is mounted to the engine accessory gearbox and its outer race stub shaft is splined directly into the engine power takeoff gear shaft.

OBS

power take off: term officially approved by the Aeronautical Terminology Standardization Committee (ATSC) - Helicopters.

French

Domaine(s)

Record 5 2001-01-12

English

Subject field(s)
  • Cycling
  • Motorcycles and Snowmobiles
DEF

A gear-shifting mechanism on a bicycle that shifts the chain from one sprocket or chainring to another.

CONT

One derailleur moves the chain from one to another of the freewheel gears. A second derailleur moves the chain from one to another of the chainwheels up front.

French

Domaine(s)
  • Cyclisme
  • Motos et motoneiges
DEF

Dispositif permettant de faire passer la chaîne d'une bicyclette d'un pignon sur un autre pignon de diamètre différent, et qui permet ainsi de changer de vitesse.

CONT

Les dérailleurs actionnés par des manettes (changement de vitesse) situés au bout du guidon ou sur le tube direction - pédalier permettent à la chaîne de passer d'un développement à l'autre.

Record 6 2000-06-28

English

Subject field(s)
  • Cycling
DEF

One of a series of teeth around the edge of a wheel which fits into one of a similar series in a similar wheel (or into a chain as in a bicycle) causing motion....

OBS

"Cog" is often used to refer to the teeth on a sprocket or freewheel. However, it appears that it is being used more and more to refer to the sprocket wheel itself, perhaps as an abbreviated form of "cog wheel".

French

Domaine(s)
  • Cyclisme
DEF

Découpure pointue; saillant de cette découpure.

CONT

La conception sans bagues de la chaîne AA75 lui permet de mieux accrocher les dents des pignons de la roue libre et des plateaux du pédalier.

Record 7 2000-04-25

English

Subject field(s)
  • Welding - Various Processes
CONT

Inertia welding (friction welding) has become a viable production welding method for parts having radial symmetry such as compressor drums. In this process, the metal preparation procedures are the same as for other techniques. The essence of the method is to convert rotational kinetic energy into heat to bring about controlled degrees of fusion and extrusion. Inertia welding can be done in air.

CONT

Intertia friction welding. Two workpiece parts to be joined are clamped rigidly in a sturdy fixed unit usually called the tailstock fixture and a rotating chuck assembly or collet drive. The spindle assembly, which includes one of the workpieces and any required flywheels, is rapidly accelerated to a pre-calculated speed, storing the energy required for welding. The spindle is disconnected from the drive source and begins to freewheel. At the same time, the ram assembly moves the non-rotating part axially to force both workpieces together, also a predetermined calculated(lbs.) thrust load. While the workpieces are thrust tightly together, friction between the interfaces convert kinetic energy stored in the rotating spindle and flywheel assemblies into heat at the interface, and finally into mechanical working of the plastic metals.

French

Domaine(s)
  • Procédés de soudage divers
CONT

On a coutume de distinguer deux modes de soudage selon la façon dont on exécute la friction : - le soudage par friction pilotée (FP) ou encore par entraînement direct ou conventionnel ( en anglais, continuous drive); - le soudage par friction inertielle (FI) ou encore par accumulation d'énergie (en anglais, Inertia welding, Inertia étant une marque de fabrique déposée par son inventeur). Ils donnent lieu à des assemblages identiques mais ont en pratique des domaines d'application distincts.

Subject field(s)
  • Cycling
DEF

A hand tool consisting of a long handle attached to a piece of chain. The chain is placed over the teeth of a cog that one wishes to remove or unsew from the freewheel body or cassette.

CONT

The rigid type of chainwhip has a radiused channel at each end, which fits over the sprocket teeth. One end is used on sprocket with up to 21 teeth, the other from 21 upwards.

French

Domaine(s)
  • Cyclisme
DEF

Démontre-couronnes qui sert à débloquer la roue libre et les couronnes. Est constitué d'un morceau de fer plat, auquel on a rivé à une extrémité un morceau de chaîne de vélo, d'une longueur de 10 à 15 cm. Pour démonter les couronnes, il faut opposer la force de deux fouets. Cet appareil assure une protection absolue des dents des couronnes.
