Les Gyroscopes. Ce sont des appareils capables de mesurer la vitesse de rotation absolue de Chandra selon deux axes différents, et dont le fonctionnement repose sur l'utilisation d'une toupie gyroscopique; celle-ci, animée d'une vitesse de rotation élevée (plusieurs milliers de tours par minute), possède une «rigidité inertielle» qui la maintient selon une direction fixe : si l'on applique un couple (une force qui tend à mettre un solide en rotation) sur l'axe de rotation de la toupie, celle-ci s'écarte beaucoup moins vite de sa direction initiale que si elle n'était pas animée d'un mouvement de rotation élevée (c'est d'ailleurs pour cette raison de stabilité que les balles des armes à feu sortent du canon en rotation.). 5, record 1, French, - axe%20de%20spin

[...] les systèmes inertiels [...] font appel à une autre loi de la physique selon laquelle les objets tournant à très haute vitesse garderont leur position relative dans l'espace. En d'autres termes, si on se met à faire tourner un objet (une toupie, par exemple) à un rythme effréné, il ne tombera pas. Conséquemment, les systèmes inertiels se composent d'un minimum de deux gyroscopes, chacun desquels supporte une masse globulaire placée à l'intérieur d'un cardan. On tient cependant les appareils d'aujourd'hui en suspension électromagnétique afin d'en réduire la friction. On orientera l'un des gyroscopes à la verticale tandis que le second y sera annexé à angle droit. Un objet tournant à la quasi-verticale s'orientera à la verticale réelle grâce aux effets de gravité. [...] S'il y a inclinaison de la plate-forme, comme par exemple lors d'un virage sur l'aile, le cardan s'incline en tandem avec l'avion tandis que la masse tournante demeure à la verticale. On peut dès lors mesurer l'angle d'inclinaison. 13, record 4, French, - cardan

Hands-on experience with gyroscopes is a good way to help children understand rotational motion. Have students experiment with spinning tops on a large, hard, flat surface such as the gymnasium floor. The students should set the tops spinning and make observations about what happens when they push the spinning tops in certain directions. They can try applying force to the gyroscopes at different heights from the ground to see how this affects the movement of a spinning top. All this can be related to gyroscopic principles (such as precession and gyroscopic inertia), as well as applications of these principles (satellites, bicycles, etc.) in real life. 3, record 18, English, - gyroscopic%20principle

A most important aspect of constructing a gyroscope is to mount the rotating wheel so that it is free of all unwanted torques. If this can be achieved, the spin vector of the gyroscope does not change from its initial value and hence always points in the same direction with respect to the fixed stars. The gyroscope thus can function as an excellent reference direction system. 1, record 20, English, - reference%20direction%20system

The critical part of a gyroscope is the spinning wheel, which an electric motor keeps it spinning at a rate of more than 20, 000 rpm. A gyroscope wheel cross section will vary in different gyroscopes, but the general design aim is to provide the greatest moment of inertial consistent with adequate strength and heat dissipation. 2, record 21, English, - spinning%20wheel

The gyroscope is a rotor, or spinning wheel, rotating at high speed in a universal mounting, called a gimbal, so its axle can be pointed in any direction. 4, record 21, English, - spinning%20wheel

Un gyroscope est essentiellement constitué d'un solide de révolution animé d'un mouvement de rotation rapide atour de son axe de symétrie. Le solide de révolution est appelé rotor ou toupie gyroscopique. Dans un grand nombre de cas d'utilisation concrète, le rotor doit pouvoir prendre n'importe quelle position dans l'espace. 6, record 21, French, - rotor

One simple form of gyrocompass consists of a single gimbal ring attached to a support rod that is an extension of a diameter of the ring. The axis of the spinning wheel is mounted inside the ring along a diameter that is at right angles to the one represented by the support rod. 2, record 22, English, - single%20gimbal%20ring
