The gyroscopes... are not perfect devices and tend to exhibit a small drift rate.

Rigidity in space. The gyroscope resists turning. When it is "gimbaled"(free to move in a given direction) such that it is free to move either in 1, 2 or 3 dimensions, any surface such as an instrument dial attached to the gyro assembly will remain rigid in space even though the case of the gyro turns. The attitude indicator(AI) and the heading indicator(HI) use this property of rigidity in space for their operation. 6, record 2, English, - gyroscopic%20inertia

A gyroscope is any rotating body that exhibits two fundamental properties: gyroscopic inertia, or rigidity in space, and precession, the tilting of the axis at right angles to any force tending to alter the plane of rotation.

Record number: 2, Textual support number: 1 CONT
L'inertie gyroscopique, appelée aussi effet gyroscopique, constitue la propriété fondamentale des gyroscopes. [...] Il s'agit d'un principe selon lequel tous les objets résistent naturellement à l'accélération ou au changement de direction. (Par exemple, les occupants d'une voiture sont projetés vers l'avant quand celle-ci s'arrête brusquement parce qu'en raison de leur inertie, les corps continuent leur mouvement vers l'avant même si la voiture s'est arrêtée.) Lorsqu'on parle d'inertie gyroscopique, on fait allusion à l'inertie que possède un corps qui tourne. Tous les objets tournant autour d'un axe ont tendance à maintenir une orientation fixe, c'est-à-dire une direction de rotation et une position fixes, si aucune force n'intervient. En d'autres mots, un objet qui tourne a tendance à rester dans la même position. 2, record 2, French, - inertie%20gyroscopique

The first type of gyroscopic instrument to successfully reduce gimbal bearing friction to an acceptable level for precision applications was the floated gyroscope. In this instrument the rotating member is sealed within a hollow cylinder which forms the inner gimbal of the gyro. This is mounted in the gyro case whith a fluid surrounding the cylinder; the density of the fluid is chosen so as to exactly float the cylinder, thus removing the weight of the inner gimbal from the bearings and greatly relieving the bearing frictional load. 2, record 4, English, - floated%20gyroscope

The gyroscope exhibits two predominant characteristics. Rigidity in space. Precession. Rigidity in space. The gyroscope resists turning. When it is "gimbaled"(free to move in a given direction) such that it is free to move either in 1, 2 or 3 dimensions, any surface such as an instrument dial attached to the gyro assembly will remain rigid in space even though the case of the gyro turns. The attitude indicator(AI) and the heading indicator(HI) use this property of rigidity in space for their operation. 2, record 11, English, - rigid%20in%20space

Le gyroscope a été imaginé par Foucault pour mettre en évidence le mouvement de rotation de la Terre. Son emploi repose sur ce principe de mécanique que lorsqu'un corps, qui n'est soumis à aucune force extérieure, est animé d'un mouvement de rotation autour d'un de ses axes principaux d'inertie, cet axe doit rester parallèle à lui-même si l'on vient à déplacer le corps d'une manière quelconque, tout en laissant l'axe libre de prendre toutes les directions. Si donc, on imagine qu'une toupie soit suspendue de manière à être soustraite à l'action de la pesanteur, et de façon que son axe de rotation puisse s'orienter dans tous les sens, il arrivera que cet axe conservera une direction fixe dans l'espace, quoi qu'il soit entraîné par le mouvement de la terre; [...] 2, record 11, French, - fixe%20dans%20l%27espace

The common ring laser gyro uses a mixture of He-Ne gas to generate coherent monochromatic radiation in two directions. Normally, the RLG is a triangular cavity filled with gas, in which two oppositely directed traveling light waves are generated by stimulated emission of light. In this case we speak of an active laser gyroscope. If, on the other hand, the lasing medium is external to the cavity, then we speak of a passive gyroscope. 1, record 12, English, - active%20laser%20gyroscope

The first type of gyroscopic instrument to successfully reduce gimbal bearing friction to an acceptable level for precision applications was the floated gyroscope. In this instrument the rotating member is sealed within a hollow cylinder which forms the inner gimbal of the gyro. This is mounted in the gyro case with a fluid surrounding the cylinder; the density of the fluid is chosen so as to exactly float the cylinder, thus removing the weight of the inner gimbal from the bearings and greatly relieving the bearing frictional load. 1, record 13, English, - gimbal%20bearing%20friction

Un roulement est composé de deux bagues une intérieure et une extérieure. Elles sont mises en contact par l'intermédiaire de bille en acier trempé, le tout est scellé. Le frottement d'un roulement est quasiment nul et il n'y a pas d'usure.
