In a skidding turn, the gyro precesses towards the inside of the turn. After return on the aircraft to straight and level flight, the instrument shows a turn in the direction of the skid. In a normal turn, the gyro precesses towards the inside of the turn. The precession error is quickly corrected by the erecting mechanism. 2, record 1, English, - erecting%20mechanism

The only really tricky part of the attitude indicator is its erecting mechanism. When power(vacuum) is first applied to the instrument, the mechanism quickly erects the gyro spindle to plumb-vertical in order to align the artificial horizon with the natural horizon. In flight, the erecting mechanism continually compensates the gyro for precession errors in order to keep it aligned throughout the course of a long flight. The design of the erecting mechanism is quite clever. In an air-driven attitude gyro, there are "pendulous vanes" suspended from pivots attached to the lower portion of the sealed gyro housing, one vane for each exhaust port. The vanes are positioned so that, when the gyro is erect, each vane half-covers its associated exhaust port. If the gyro tilts so that its axle is not plumb, the pendulous vanes shift so that one exhaust port is more-than-half-covered and the opposite exhaust port is less-than-half-covered. The resulting imbalance of discharge air exerts a force on the rotor housing at right angles to the direction of tilt, causing the gyro to precess to the erect position. As soon as the gyro is erect, the pendulous vanes return to a balanced condition to remove the precessing force. Pure magic! The erecting mechanism can erect the gyro quite quickly at initial power-up because the gyro doesn’t exhibit much gyroscopic rigidity at low rotor RPMs. Typically, the horizon bar becomes level within the first 10 or 15 seconds, and then its oscillations(caused by precessional nutation of the gyro) are damped out within a minute or so as the rotor comes up-to-speed. 3, record 1, English, - erecting%20mechanism

The gas bearing gyro involved a spinning ball the size of a large marble, spinning inside a spherical housing that floated on a layer of gas. This greatly reduced contact and friction, allowing the gyro to run indefinitely. One such gyro had been put into motion in 1952 and was still spinning. 3, record 2, English, - gas%20bearing

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 3, English, - gyro%20housing

On appellera «carter» le solide [...] qui porte le gyro au moyen de paliers A et A'. Cette dénomination de carter est parfaitement adaptée puisque le gyro doit être protégé des poussières et régulé en température. De plus la grande vitesse de rotation présente un danger pour l'environnement extérieur. [...] Le carter s'appelle aussi «élément sensible», car c'est lui qui reçoit directement les effets du gyro et lui seul est vraiment observable.

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 4, French, - bo%C3%AEtier%20du%20gyroscope
