Record number: 1, Textual support number: 1 DEF
The characteristic of a gyro resulting from lack of coincidence of the center of supporting forces and the center of mass. It gives rise to torques caused by linear accelerations that lead to acceleration-sensitive drift rates. 4, record 1, English, - unbalance
Record number: 1, Textual support number: 1 CONT
Gyro drift is caused by random and fixed torques, such as those resulting from bearing friction or mass unbalance. Mass unbalance results in a torque due to gravity. 5, record 1, English, - unbalance

Mauvaise répartition des masses d'une pièce ou d'un ensemble tournant, qui fait que son centre de gravité n'est pas sur l'axe de rotation. 4, record 1, French, - balourd
Record number: 1, Textual support number: 1 CONT
Dans un gyroscope intégrateur flottant, un décalage de 2 nm [...] entre le centre de gravité et le centre de poussée d'Archimède produit un balourd suffisant pour créer une dérive de 10 [puissance -2] degrés par heure. 5, record 1, French, - balourd
Record number: 1, Textual support number: 2 CONT
La dérive du gyroscope [...] est causée par des couples [...] fortuits et permanents, tels que ceux résultant de la friction dans les roulements et le déséquilibre de la masse. Le déséquilibre de la masse provoque un couple dû à la gravité. 3, record 1, French, - balourd
