English

Subject field(s)
  • Nuclear Physics
  • Nuclear Fission Reactors
DEF

A correction applied to the resonance integral of an isolated fuel element or fuel assembly in order to obtain the resonance integral of the same element or assembly when near other elements or assemblies in the calculation of the neutron balance in a reactor cell.

OBS

Dancoff correction: term and definition standardized by ISO.

French

Domaine(s)
  • Physique nucléaire
  • Réacteurs nucléaires de fission
DEF

Dans les calculs du bilan neutronique d'une cellule du réacteur, correction apportée à l'intégrale de résonance d'un élément combustible isolé ou d'un assemblage combustible isolé en vue d'obtenir l'intégrale de résonance du même élément ou assemblage lorsqu'il est au voisinage d'autres éléments ou assemblages.

Subject field(s)
  • Spacecraft
  • Space Exploration Equipment and Tools
  • Launchers (Astronautics)
CONT

Many spacecraft use small rockets called thrusters to move around in space. Thrusters can change the speed and direction of a spacecraft. They allow a spacecraft to steer in space, to jump to a higher orbit, or to fall back to Earth.

CONT

The control rocket is a vernier or other rocket used to control the attitude of, or slightly change the speed of, a spacecraft.

CONT

The propulsion subsystem featured sets of small thrusters and a main engine. The thrusters were used to perform Odyssey's attitude control and trajectory correction manoeuvres, while the main engine was used to place the spacecraft in orbit around Mars. The main engine, which used hydrazine propellant with nitrogen tetroxide as an oxidiser, produced a minimum thrust of 65. 3 kilograms of force. Each of the four thrusters used for attitude control produce a thrust of 0. 1 kilogram of force. Four 2. 3-kilogram-force thrusters were used for turning the spacecraft. In addition to miscellaneous tubing, pyro valves and filters, the propulsion subsystem also included a single gaseous helium tank used to pressurise the fuel and oxidiser tanks. The propulsion subsystem weighed 49. 7 kilograms.

DEF

Moteur-fusée de très petite poussée.

CONT

Des micropulseurs télécommandés développent des impulsions radiales axiales qui corrigent l'attitude ou la position du satellite sur son orbite.

OBS

On prévoit dans de nombreux satellites de petits propulseurs [...] dont les emplacements sont fixes.

OBS

Micropropulseur télécommandé.
