The rotor of the air-driven gyro is mounted in a sealed housing. Filtered air is brought into the gyro housing through passages in the rear pivot, the gimbal ring, and the side pivots. The air then blows against the rotor through two angled nozzles on opposite sides of the housing. The circumference of the rotor is machined with dozens of little bucket-like cutouts which allow the airflow to spin the rotor like a waterwheel (but a whole lot faster). Having done its work, the air then exits through exhaust ports on the lower part of the sealed gyro housing, whereupon it is sucked out of the instrument case by the vacuum pump. 3, record 10, English, - gyro%20housing

The horizon bar is linked to the gyro by a lever, attached to a pivot on the rear of the gimbal frame and connected to the gyro housing by a guide pin. 5, record 10, English, - gyro%20housing

The "dynamic tuning" of a dynamically tuned gyroscope(DTG) refers to a clever gimbal configuration that balances the torques from the support flexure with dynamic spring torques created by gimbal "flutter" while the gyro rotor spins. This configuration allows the gyro rotor to spin to a "free" rotor in two axes. 2, record 11, English, - dynamically%20tuned%20gyro

Les gyroscopes à suspension dynamiquement accordée [...] sont des gyroscopes «deux axes», à faible débattement angulaire, dont la toupie est reliée au boîtier par un (ou deux) joints de Hooke; la charnière ainsi constituée se trouve à l'intérieur de la toupie. [...] Ces appareils présentent les avantages suivants : pas de liquide de flottaison (gyroscopes dits «secs»), pas de fils d'amenée de courant à l'élément sensible, pas de roulements à billes dans l'élément sensible, moteur d'entraînement séparé de l'élément sensible. 6, record 11, French, - gyroscope%20%C3%A0%20suspension%20dynamiquement%20accord%C3%A9e

Attitude indicator components(vacuum-driven). The rotor, mounted in a sealed housing, spins in a horizontal plane about the vertical axis. The housing pivots about the lateral axis on a gimbal, which in turn is free to pivot about the longitudinal axis. The instrument case is the third gimbal necessary for universal mounting. The horizon bar is linked to the gyro by a lever, attached to a pivot on the rear of the gimbal frame and connected to the gyro housing by a guide pin. 5, record 13, English, - case

Un gyroscope est essentiellement constitué d'un solide de révolution animé d'un mouvement de rotation rapide autour 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. À cet effet on rend le rotor solidaire du boîtier qui le contient au moyen d'un système de deux cadres mobiles l'un par rapport à l'autre. 4, record 13, French, - bo%C3%AEtier%20du%20gyroscope
