Record 1 2015-08-14

English

Subject field(s)
  • Ballistics
  • Guns (Land Forces)
DEF

The condition in which the projectile always points to the right of the trajectory.

OBS

Because the trajectory is continually falling away, the nose of the precessing projectile will point above the trajectory more so than below it. The result is that a certain degree of force is continually being exerted under the nose of the projectile. The dominating gyroscopic effect is to keep the nose of the projectile pointed to the right.

French

Domaine(s)
  • Balistique
  • Canons (Forces terrestres)
DEF

État du projectile qui pointe toujours vers la droite de la trajectoire.

OBS

La trajectoire descendant continuellement, l'avant du projectile, en mouvement de précession, pointe plus au-dessus qu'au-dessous de la trajectoire. Une certaine force s'exerce alors sans cesse sous l'avant du projectile. L'effet gyroscopique dominant est de maintenir l'avant du projectile pointé vers la droite.

OBS

lacet d'équilibre : terme et définition uniformisés par le Comité de terminologie française du Conseil de doctrine et de tactique de l'Armée de terre.

Record 2 2003-12-08

English

Subject field(s)
  • Launching and Space Maneuvering
CONT

The ISS attitude will vary between +15 degrees and-15 degrees for each roll and yaw axis of LVLH [Local Vertical/Local Horizontal] and between +15 degrees to-20 degrees for the pitch axis... At any point on the ISS non-articulated portion, which means the portion excluding rotating elements such as photovoltaic arrays and Thermal Control System(TCS) radiators, the ISS will provide estimates of the ISS LVLH attitude to an accuracy of 3 degrees per axis(3 sigma) and inertial rates to an accuracy of 0. 01 degrees per second per axis(3 sigma). When controlling to the TEA [Torque Equilibrium Attitude] with non-propulsive effectors, the ISS will maintain attitude stability to 3. 5 degrees per axis per orbit.

OBS

ISS attitude: term officially approved by the International Space Station official approval Group (ISSOAG).

  • Lancement et manœuvres dans l'espace
