Record number: 1, Textual support number: 1 CONT
Indicateur de virage et d’inclinaison latérale. [...] Le principe de base gouvernant le fonctionnement de l'indicateur de virage est la précession gyroscopique. Le rotor est monté sur un cardan. Lorsque l'avion effectue un virage à droite ou à gauche, le rotor «précesse» autour de son axe de rotation et fait rouler le cardan. À son tour, le mouvement rotatoire du cardan fait bouger l'aiguille sur le devant de l'instrument. Un ressort renvoie le gyroscope au neutre lorsque l'avion cesse de virer. L'indicateur de virage indique le «taux» de virage et non «l'amplitude». Le taux standard, ou virage au taux 1, est égal à 3 degrés par seconde ou 360 degrés en deux minutes. 3, record 1, French, - indicateur%20de%20virage

Horizon sensors [are] the primary means for directly determining the attitude of a spacecraft relative to the Earth ... The attitude of spacecraft relative to Earth is one of the most important aspects of attitude determination and control, particularly for communications (TDRSS), weather (GOES), Earth resources (LANDSAT), satellites, etc. Earth cannot be treated as a point source like the Sun, especially for near Earth satellites for which Earth covers about 40% of the sky. Therefore, merely detecting the Earth is by no means sufficient for attitude determination, even for the most crude attitude determination requirements. Hence most sensors are designed to detect the Earth's horizon. Horizon sensors are infrared devices that detect the contrast of the cold of space and the warmth of the Earth (or other body). 5, record 4, English, - horizon%20sensor

The vacuum-drive heading indicator is the simplest of many types of gyro-controlled directional indicators designed to provide stable heading reference. ... Errors. The chief cause of precession, causing the card to creep or drift, is bearing friction. Normal movement of the gimbal rings produces friction, which is increased if the bearings are worn, dirty, or improperly lubricated. Other sources of precession error include unbalanced gyro components and the effect of the earth's rotation. The latter effect depends upon the position of the instrument in relation to the earth, and is not appreciable unless a flight involves considerable change in latitude. 1, record 10, English, - unbalanced

Like flywheels, CMGs [control moment gyro] can be considered either as generators of torques applied to the satellite or as generators of kinetic moment exchanged with the satellite momentum. The axis of the kinetic and dynamic (gyroscopic) moments produced by a CMG are changing in the satellite reference system: they rotate in the plane perpendicular to the tilt axis. Moreover, the higher the dynamic moment, the faster they rotate. To generate a kinetic or dynamic moment in a given direction, it is necessary to combine at least three elementary kinetic moments or gyroscopic torques in variable, non-coplanar directions. 1, record 11, English, - kinetic%20moment
