The "dynamic tuning" of a dynamically tuned gyroscope (DTG) refers to a clever gimbal configuration that balances the torques from the support flexure with dynamic spring torques created by gimbal "flutter" while the gyro rotor spins. This configuration allows the gyro rotor to spin to a "free" rotor in two axes. 2, record 1, English, - tuning%20condition

Équations de la gyroscopie [...] Suspension dynamique accordée [...] le principe : Les paliers des articulations S1-S2 et S2-S3 ne sont plus des roulements, mais remplacés par [des] joints de Hooke ou encore des barres de torsion élastiques. Un calcul complexe montre qu’à une vitesse précise dite d’accord, la raideur des joints est compensée [...] par le couple des forces d’inertie centrifuge et la suspension ne présente plus alors aucune rigidité. Les débattements de la toupie, en orientation, sont limités à quelques degrés. La condition d’accord définissant la vitesse correcte relie les caractéristiques des barres de torsion et un moment d’inertie particulier de l’anneau interne. On l’appelle la condition de tuning et c’est ce qui donne à la technique le nom de gyroscope accordé. 3, record 1, French, - condition%20d%26rsquo%3Baccord

Le principe de fonctionnement du gyroscope à suspension accordée consiste à réaliser une exacte compensation entre la raideur statique négative-K, due aux barres de torsion, et la raideur dynamique moyenne positive, due à l'inertie de l'anneau intermédiaire. Cela se traduit par la condition de compensation ou d’accord(tuning) suivante :[formule xyz]. 2, record 1, French, - condition%20d%26rsquo%3Baccord
