Inertial platform ... Stable platforms utilizing gyroscopes references have been successfully used for several decades as attitude and heading reference systems (AHRS), fire control baselines for aircraft, ships, missiles, and for inertial navigators. The part of the platform system, which mechanizes the reference is called "controlled member" or "stable element". 2, record 1, English, - controlled%20member

For a three-gimbal platform ... the inner gimbal or controlled member is the stable platform on which the three gyros and accelerometers are mounted. As the vehicle to which the system is attached moves, the gyros sense any rotation and drive the gimbals in the opposite direction to null the gyro rate. As a result, the inner platform remains fixed in inertial space. 5, record 1, English, - controlled%20member

On distingue deux types de systèmes inertiels : - Les systèmes sur cardans, dont la plate-forme contenant les accéléromètres est montée sur les cardans internes de trois gyroscopes. La plate-forme est isolée de toute rotation du véhicule et son attitude reste constante pendant le mouvement du système. Ces dispositifs complexes sont précis, mais complexes et onéreux. - Les systèmes dits «strap-down», qui utilisent des accéléromètres et des gyroscopes soumis aux mouvements du véhicule. Ces systèmes sont plus simples à mettre en œuvre, moins chers mais moins précis. 1, record 1, French, - cardan%20interne

Le gyroscope de Foucault est une toupie rectifiée [...] formée d'une masse de cuivre [...] montée sur un axe dont les deux extrémités sont fixées sur un anneau lui-même suspendu aux deux extrémités du diamètre perpendiculaire à celui de l'axe qui porte la masse de cuivre, de sorte que celle-ci peut prendre toutes les inclinaisons possibles sur l'horizon. Les deux pivots de ce premier anneau reposent sur un deuxième anneau plus grand, monté lui-même sur pivots lui permettant une rotation verticale. [...] Si on fixe horizontalement l'anneau intérieur, l'axe de rotation ne pourra plus se déplacer que dans un plan horizontal. 3, record 1, French, - cardan%20interne

Gyroscopes can be used as devices for direction finding, guidance, and control. If a gyroscope, mounted on its gimbal rings, is set spinning about a horizontal axis, and the outer gimbal ring is rotated in a horizontal plane, then the inner gimbal ring, carrying the flywheel, tilts up out of the horizontal plane in which it, too first lay. After a few oscillations, damped out by friction, the axis of spin of the gyroscope settles down along a vertical direction. Inertial guidance systems make use of very similar phenomena. Once a gyroscope has been set spinning about a chosen axis, any motion that would cause it to deviate from this direction calls into existence a torque that can be used as an error signal to control corrective maneuvers... Some of the most important applications of gyroscopic phenomena are in aircraft instruments. A free(perfectly balanced) gyroscope can give a constant indication of a chosen reference direction for checking the correct course, and a gravitationally loaded gyroscope can be used to identify the true vertical at all times and so define an artificial horizon against which the pilot can measure the angles of bank and climb. 2, record 3, English, - gyroscopic%20phenomenon

Le gyroscope construit par Foucault 1852 est un appareil qui dérive de son pendule. Comme lui, il met en évidence les effets de la rotation de la terre. Il est constitué d'une masse lourde, appelée rotor, en mouvement de rotation rapide autour d'un axe restant fixe dans un référentiel galiléen. Le gyroscope se caractérise par un moment cinétique élevé. Il existe des gyroscopes dont l'axe en rotation est lié à l'armature de l'appareil par deux axes et d'autres reliés à un seul axe. On retrouve le phénomène gyroscopique dans des jouets tels que les toupies. Il est utilisé dans des appareils appelés compas gyroscopiques servant au guidage des missiles, des avions et des satellites. 2, record 3, French, - ph%C3%A9nom%C3%A8ne%20gyroscopique

A conventional gyroscope is a mechanism comprising a rotor journaled to spin about one axis, the journals of the rotor being mounted in an inner gimbal or ring, the inner gimbal being journaled for oscillation in an outer gimbal which in turn is journaled for oscillation relative to a support. The outer gimbal or ring is mounted so as to pivot about an axis in its own plane determined by the support. Hence the outer gimbal possesses one degree of rotational freedom and its axis possesses none. The inner gimbal is mounted in the outer gimbal so as to pivot about an axis in its own plane which axis is always normal to the pivotal axis of the outer gimbal. Hence the inner gimbal possesses two degrees of rotational freedom and its axis possesses one. 3, record 5, English, - outer%20gimbal
