The heading indicator (HI) uses the principle of rigidity in space for it’s operation. The gyro is mounted such that it registers changes around the vertical axis only; i.e. direction changes. The compass card attached to the gyro appears to the pilot as though it is turning. In reality, it and the attached gyro are remaining rigid in space, while the aircraft and case turn about the gyro. The HI is not automatically synchronized with the magnetic compass. It must be set to the compass heading while level on the airport surface prior to take-off. 13, record 1, English, - directional%20gyroscope

Le conservateur de cap, ou gyroscope directionnel, est l'un des trois instruments à gyroscope. Aligné avec le compas, il donne une indication précise et stable concernant le cap magnétique de l'appareil. Le conservateur de cap constitue une aide importante car le compas est sujet à des erreurs causées par l'accélération, la décélération et la courbure du champ magnétique terrestre, particulièrement sous les hautes latitudes. Il arrive fréquemment que le compas oscille; il est particulièrement difficile à lire dans les turbulences ou pendant les manœuvres. Fonctionnement. Le gyroscope du conservateur de cap pivote dans un plan vertical. Une carte comportant des caps maintient son orientation lorsque l'avion tourne.

Angular amplitudes and rates, and linear accelerations were measured with a six-axis-gyroscope. High-frequency vibrations were characterized with a triaxial accelerometer. Additional measurements from an onboard gyroscope with better resolution were used as a correlation factor between the two gyroscope systems. Fourier analysis of angular amplitudes and linear accelerations determined relevant frequencies for the system. Sources of error for the gyroscope system such as temperature drift and axes misalignment were identified and characterized. 2, record 4, English, - platform%20axes%20misalignment

Notice that there is no knob to set the heading of the DG [directional gyro] to match that of the compass. Why? Because it is slaved. Slaved? Back in the tailcone of the aircraft, away from all ferrous metal, is a magnetic compass. The output of this compass is electrically "enhanced" and amplified through a "flux gate"... This signal is fed to the HSI to drive the DG portion of the unit. What this means is that the reading is very accurate, not subject to the vagrancies of the regular magnetic compass, and is constantly being corrected for drift. On some aircraft, this signal is also used to slave the ADF heading card. 2, record 5, English, - corrected%20for%20drift

Dead reckoning is a technique of computing the position of a vehicle from its distance and heading measurements. It is an inertial system which uses two independent sensors from which distance and heading information can be extracted. Because each position is relative, cumulative drift errors occur on an average of 2% of the distance traveled. The system consists of a magnetic compass or gyroscope for heading and odometer for distance. Dead reckoning is often combined with map matching to correct for drift errors. It performs well when combined with highly accurate digital maps. It can also be used to back up GPS during satellite visibility outages. 3, record 10, English, - cumulative%20drift

Gyroscope drift rate effects are usually classified into three groups... The final group consists of drift rates proportional to the square of the off-axes acceleration. This is called the nonisoelastic or compliance effect. 1, record 11, English, - nonisoelastic%20effect

Dans cette étude de la quantification, le mouvement est supposé le résultat d'échanges de matière entre l'électron et le proton. Ces échanges prennent place dans toutes les directions de l'espace. De ce fait la rotation orbitale doit être considérée comme le résultat d'une action mécanique qui agit dans deux directions orthogonales. En d'autres termes la rotation peut être considérée comme la somme de deux rotations orthogonales. Il en résulte que le champ magnétique qui correspond à une action sur une seule direction de plans ne peut modifier que la moitié de l'action associée à la rotation. D'autre part les doublets ont en fait pour origine la possibilité pour l'électron de pouvoir tourner pour une même quantification angulaire avec une masse constante ou variable indépendamment de la vitesse radiale et rien n'indique que les doublets correspondent à des états de spin-up et de spin-down. 1, record 13, French, - quantification%20angulaire

Quantification. Une grandeur est quantifiée lorsqu'elle ne peut prendre qu'un ensemble de valeurs discontinues. Ces valeurs sont des multiples entiers ou demi-entiers de l'une d'elles, nommée quantum de la grandeur considérée. 2, record 13, French, - quantification%20angulaire

Gyroscope drift rate effects are usually classified into three groups. The first group is independent of applied acceleration... The second group includes effects proportional to translational acceleration. This group covers such things as static unbalance of the inner gimbal assembly, i. e., the displacement between the center of support or buoyancy and the center of mass. 4, record 14, English, - translational%20acceleration

Selon [...] [le Principe d'Équivalence (PE) (postulat de Albert Einstein]), un effet d'accélération (inertie) et un effet gravitationnel (attraction entre deux masses gravitationnelles) sont équivalents. [...] les «sphères de Galilée» restent toujours l'idée maîtresse pour tester le PE. Notre idée est de tirer parti de la situation zéro-g pour comparer l'accélération angulaire de deux masses, plutôt qu'une accélération de translation, ce qui nous donnerait l'opportunité de faire «exploser» théoriquement la précision des résultats. 3, record 14, French, - acc%C3%A9l%C3%A9ration%20de%20translation
