... in order to be free of gravity, gyroscopes can be placed in a Cardan mount, which permits the gyroscopes to remain free of forces exerted on the systems of which they are a part. In the Cardan mount the shaft of a gyroscope wheel is mounted in a gimbal ring, which in turn is mounted in a larger gimbal ring along a diameter that is at right angles to the axis of the wheel. 6, record 2, English, - free%20gyro

Some gyrosyn compass are fitted with a dial switch. In one position, the complete system is in operation. In the other position, the flux valve is shut off and the instrument operates as a free directional gyro.

Certains gyrocompas sont munis d'un bouton-interrupteur. Une position indique que le système complet est en opération. Une autre indique que la sonde magnétométrique est coupée et que l'instrument fonctionne comme un conservateur de cap autonome. Cette caractéristique est nécessaire pour l'utilisation de l'instrument aux hautes latitudes polaires ou dans toutes les circonstances où les indications magnétiques ne sont pas fiables. 1, record 3, French, - conservateur%20de%20cap%20autonome

conservateur de cap : Gyroscope qui indique précisément et rapidement les changements de cap d'un appareil, souvent appelé «gyroscope directionnel». Dans la mesure où le conservateur de cap fonctionne avec un gyroscope, il fournit une indication régulière et précise du cap ou des virages. Le compas, qui est quant à lui soumis à l'accélération ou à la décélération, aux dénivellations et autres erreurs de navigation, oscille souvent ou a un tour d'avance ou de retard. Toutefois, comme les gyroscopes sont affectés par la précession, le pilote doit périodiquement régler le conservateur de cap en fonction du compas (sauf si le conservateur de cap est électroniquement asservi au compas). 3, record 3, French, - conservateur%20de%20cap%20autonome

Three-frame gyroscopes. The unrestrained or "free" three-frame gyroscope has little practical use, because its spin axis is subject to tilting and drifting owing to the rotation of the Earth. 1, record 4, English, - unrestrained%20three%2Dframe%20gyroscope
Record number: 4, Textual support number: 1 OBS
The Two Frame Gyroscope. When the rotor is spinning and the spin axis is in a horizontal plane a definite resistance will be felt owing to gyroscope inertia, at the same time the spin axis will begin to precess in a vertical plane and will continue to do so with sufficient power to lift light weights until all the gyroscopic inertia disappears due to the rotor slowing and stopping. The Three Frame Gyroscope. If the base of a three framed gyroscope is held in the hand with the rotor spinning and turned about any of the three axes, the rotor will continue to point in the original direction in space. This property is known as gyroscope inertia. 2, record 4, English, - unrestrained%20three%2Dframe%20gyroscope

L'analyse des données provenant des trois encodeurs optiques du gyroscope démontre sans doute qu'au moins un des axes s'est bloqué très tôt au cours du vol. Le gyroscope n'étant plus libre de pivoter sur trois degrés de liberté, des forces de précession sont probablement apparues, causant des rotations aux axes libres qui ne correspondent pas à des mouvements réels de la fusée en vol. Comme le gyroscope a pu être récupéré, un examen de la structure a été effectué après le vol. L'équipe du Gaul a pu constater que le gyroscope a subi des dommages importants : les cadres externes et internes sont très déformés, l'axe des cadres brisé, plusieurs fils sont rompus et l'encodeur de l'axe des cadres présente une grande résistance à la rotation. 2, record 4, French, - gyroscope%20libre%20%C3%A0%20trois%20cadres
