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 5, English, - controlled%20member

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.

... gyros and accelerometers have an offset, known as bias. The gyro bias for instance, shows itself after integration as an angular drift, increasing rise linearly over time(ramp)... To compensate for sensor drift, a process called augmentation is used, whereby gyro and acceleration errors are compensated by utilising other system states. For instance the angular drift error of a gyro after integration can be compensated, if true angular measurements are taken. Comparing the two shows then the gyro drift. Assuming that inertial systems are generally operated around an equilibrium position and thus linear acceleration integrates to zero over time, then attitude can be processed via gravitational acceleration, thus giving true angular measurements to compensate gyro drift. 1, record 9, English, - angular%20drift

The gyrosyn compass combines the functions of both the directional gyro and the magnetic compass. It provides stable compass headings in rough air, is north seeking like a magnetic compass, but is free from northerly turning error and oscillation. It does not precess and, therefore, does not require resetting as does the directional gyro. The gyrosyn compass system incorporates a flux valve that senses the earth's magnetic lines of force through electromagnetic induction. 6, record 11, English, - gyromagnetic%20compass

Precession error. Frictional forces in the gyros system cause it to precess. This precession causes a creep or drift in the reading on the card, amounting approximately 3 degrees in 15 minutes. The gyro is also subject to apparent precession. Gyroscopic inertia keeps the spinning gyro fixed in space so that, relative to space, it does not move. But the earth rotating underneath it gives it an apparent motion relative to the earth. This causes an apparent drift, or precession, which varies with latitude... Precession error, both mechanical and apparent, must be corrected for at regular intervals of about 15 minutes. 1, record 21, English, - apparent%20precession%20error

... AlliedSignal has changed the way it manufactures its highly accurate gyros in an effort to stretch their service lives to prevent a future shutdown. But the basic design of the gyros has not changed, since they are about twice as accurate as the next-best gyros available, according to Hubble Program Manager John Campbell. The problem is the tiny leads that carry power to the gyro rotors. Sunk in a thick damping fluid, the hair-like wires corrode over time and break. The six new gyros Discovery's crew will install retain the fine power leads, but the damping fluid was loaded into the gyros in a manner that engineers hope kept oxygen out of the system, reducing the risk of oxidation. 5, record 27, English, - damping%20fluid

Angular rate gyro accuracy is characterized by two parameters : scale factor and drift. The scale factor describes the capability of the gyro to accurately sense angular velocity at different angular rates. This value is used to convert the voltage output from the gyro into an angular rate. System imperfections can cause small variations in the scale factor. These variations appear as a factor at the output of the gyro.

Angular velocity is the time rate of change of angular displacement. More simply it is a measure of how fast an object is rotating. For example, the measure of a skater’s spinning speed during a sit spin is called angular velocity. Angular velocity is calculated by subtracting the initial angular position from the final angular position and dividing by the time it took to get from the initial to final position. Angular velocity is measured in radians/second (SI units) or degrees/second or revolutions/second (English units). 4, record 29, English, - angular%20velocity

Precession error. Frictional forces in the gyro system cause it to precess. This precession causes a creep or drift in the reading on the card, amounting approximately 3 degrees in 15 minutes. The gyro is also subject to apparent precession. Gyroscopic inertia keeps the spinning gyro fixed in space so that, relative to space, it does not move. But the earth rotating underneath it gives it an apparent motion relative to the earth. This causes an apparent drift, or precession, which varies with latitude...

Where positioning accuracy is concerned, it may seem surprising that the accuracy provided by the gyros has more impact than that of the accelerometers... This is due to the fact that navigation in fact occurs on a sphere, the Earth. It will therefore be readily understood that traveling along a straight line on the Earth comes down in fact to a rotation, and that rotation is detected by the gyros. In practice, gyros are subject to a zero-error known as gyro bias : When there is no rotation, a gyro should indicate zero, but in fact measures something that is the bias value. When an inertial navigation system is immobile, the gyros measure bias values that are integrated by the calculator and the unit thinks that it is rotating, and therefore advancing across the surface of the terrestrial globe, which generates a position error. It will be understood that position error shows linear growth over time and there is a direct relationship between the accuracy of a gyro and position drift. 1, record 44, English, - zero%2Derror

Angular rate gyro accuracy is characterized by two parameters : scale factor and drift. The scale factor describes the capability of the gyro to accurately sense angular velocity at different angular rates. This value is used to convert the voltage output from the gyro into an angular rate. System imperfections can cause small variations in the scale factor. These variations appear as a factor at the output of the gyro. Gyro drift characterizes the ability of the gyro to reference all rate measurements to the nominal zero point. 3, record 48, English, - scale%20factor

[The turn coordinator] is a level, with a ball that shows the pilot the direction and rate of the turn. The ball shows the quality or coordination of the turn and the dipped wing tells the angle of bank. In more complex airplanes, the TC is often a gyro and is part of the vacuum system. The turn coordinator "backs up" the information from the attitude indicator. 3, record 58, English, - ball

L'indicateur de virage se compose en fait de deux instruments. Le gyroscope indique le taux de virage de l'appareil, c'est-à-dire la vitesse à laquelle il change de direction. Une bille située dans un tube appelé «inclinomètre» ou «indicateur de glissade/dérapage» indique la qualité du virage, c'est-à-dire s'il est ou non stabilisé. [...] La bille noire de l'indicateur de glissade/dérapage se maintient entre les deux lignes verticales de référence lorsque les forces d'un virage s'équilibrent et que l'appareil est en vol coordonné.

Attitude gyros, technically called vertical gyros because of the orientation of their spin axis, do precess, but correction is applied automatically. All attitude gyros have an automatic erection system that drives the gyro back to vertical when it precesses. The erection system detects gravity by means of a pendulous sensor that in turn opens air blast vanes on an air-driven gyro or powers electric torquer motors to drive the gyro back to vertical when it precesses. 3, record 59, English, - electrical%20torquer

The directional gyroscope forms a standard reference for the pilot and navigator. It is a three-frame gyroscope with its spin axis in the horizontal plane. As soon as tilt develops, a switch is closed between the gyroscope housing and the vertical gimbal ring and a motor introduces a torque in the horizontal plane that causes the gyroscope to precess back toward the horizontal. 3, record 60, English, - vertical%20gimbal%20ring

The source of power for the gyro is the engine-driven vacuum pump(or venturi) which sucks air from the rear of the instrument case. This causes air under atmospheric pressure to pass through the filtering system, thence through an air bearing into the hollow vertical gimbal ring. The air then passes through the air nozzle and jets, striking the rotor at a point just above the plane of the horizontal gimbal. 4, record 60, English, - vertical%20gimbal%20ring

Le gyroscope de Foucault est une toupie rectifiée avec grande précision, formée d'une masse de cuivre de forme torique ou ellipsoïde, 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. L'expérience et la théorie indiquent que la masse exécute une série d'oscillations autour de la méridienne, sur laquelle il vient finalement se fixer quand les frottements ont absorbé ce mouvement oscillatoire, pourvu toutefois que la rotation de la toupie dure assez longtemps. Si, au contraire, on fixe l'anneau vertical dans un plan perpendiculaire au plan méridien, l'axe de rotation ne pourra plus se déplacer que dans ce plan méridien. 1, record 60, French, - anneau%20vertical
