Subject field(s)
  • Flight Instruments and Equipment (Aeroindustry)
  • Aircraft Piloting and Navigation
  • Navigation Instruments
CONT

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.

CONT

The directional gyroscope is used in aircraft and is sometimes called a self-levelling free gyroscope corrected for drift.

Domaine(s)
  • Instruments et équipement de bord (Constructions aéronautiques)

CONT

Déplacement d'un gyroscope corrigé. Dans le cas d'un gyroscope corrigé pour la dérive apparente due à la rotation de la Terre, on applique une correction de 15° sin latitude par heure à l'écrou de compensation de latitude.

OBS

Description et fonctionnement du gyrolaser [...] sources d'erreurs et solutions apportées [...] dérive de l'onde stationnaire (onde bloquée dans la cavité et qui est toujours en rotation même si la cavité reste immobile) [...] solutions apportées : on élimine la dérive de l'onde stationnaire en utilisant des cavités où deux écoulements de gaz se font en sens inverse, par exemple avec une seule anode et deux cathodes placées sur les 2 côtés opposés d'un carré. Ainsi les mouvements gazeux se compensent et la dérive est presque éliminée. De plus, on utilise un dispositif électronique supplémentaire qui mesure et compense la dérive résiduelle de sorte que seules des perturbations imprévisibles peuvent engendrer une erreur systématique.

In its simplest form, an inertial navigation system(INS) consists of an inertial measurement unit(IMU), the navigation computer, and a computer interface. Therefore, the inertial navigation system aboard an aircraft provides, through self-contained equipment, aircraft acceleration, velocity, position, attitude, and heading to the onboard navigation computer and other aircraft subsystems... For certain operations and/or missions... dual or triple redundant inertial navigation systems are required... In a dual INS configuration... as long as either inertial navigation system is providing valid data, its output can be used as the primary reference source for the navigation subsystem.

Key term(s)
  • dual redundant INS

CONT

When the magnetic slave card is used, the magnetic error derived from the flux valve, and modified by variation from the controller, is amplified, limited and demodulated in the magnetic slave card. The output is fed to the heading card and the output is used to drive the DG [directional gyro] torquers.

Lorsqu'on se sert de la carte d'asservissement magnétique, le signal d'erreur du détecteur de magnétisme, modifié par l'angle de déclinaison du «controller», est amplifié, limité et détecté. Son signal de sortie est envoyé à la carte de cap qui à son tour l'utilise pour commander les moteurs couples du DG [gyroscope directionnel].
