HALL THRUSTER [4 records]

Record 1 2004-11-09

English

Subject field(s)
  • Launchers (Astronautics)
DEF

A type of Hall effect thruster.

CONT

This plasma thruster relies on the "Hall effect" to accelerate xenon ions to speed up to 16, 000 km/hour. It is able to deliver 70 mN of thrust with a specific impulse(the ratio between thrust and propellant consumption) 5 to 10 times better than traditional chemical thrusters and for mush longer durations(months or even years, compared to the few minutes’ operating times typical of traditional chemical engines).

French

Domaine(s)
  • Lanceurs (Astronautique)
DEF

Moteur en cours de développement (Russie, France, USA) pour la propulsion et le contrôle des gros satellites et des sondes interplanétaires dans lequel le carburant est remplacé par un gaz rare.

Record 2 2004-05-04

English

Subject field(s)
  • Missiles and Rockets
  • Launchers (Astronautics)
CONT

In Electro-Static thrusters, the propellant is ionized and the resulting ions are accelerated through an electric potential. Common examples include Hall effect and Kaufmann type thrusters. Electro-Magnetic thrusters utilize electric and magnetic body forces to accelerate ions. The most common type of electromagnetic thruster is the magnetoplasmadynamic thruster, or MPD.

Record 3 2004-05-04

English

Subject field(s)
  • Launchers (Astronautics)
CONT

The Hall thruster is an electric rocket engine, which accelerates ions in crossed electric and magnetic fields in a quasineutral plasma.

CONT

In Electro-Static thrusters, the propellant is ionized and the resulting ions are accelerated through an electric potential. Common examples include Hall effect and Kaufmann type thrusters.

French

Domaine(s)
  • Lanceurs (Astronautique)
CONT

Étude expérimentale dans différents régimes de fonctionnement du comportement de 2 types de propulseurs à effet Hall pour les sondes spatiales : un propulseur à forte puissance et un propulseur bi-étage en utilisant principalement la fluorescence induite par laser comme diagnostic.

CONT

[...] dans le propulseur électromagnétique, le projectile (un morceau de résine isolante) porte sur sa face arrière de minces feuilles de cuivre, qui fondent rapidement et se vaporisent lorsque elles sont traversées par un courant de très forte intensité ; on est alors en présence d'un plasma (gaz ionisé conducteur, localement neutre). La température de ce plasma est suffisamment élevée pour que tous les atomes de cuivre soient ionisés [...]
