HYDRAZINE THRUSTER [5 records]

Record 1 2017-11-16

English

Subject field(s)
  • Spacecraft
DEF

A rocket engine which works on the principle of externally heating a pressurized propellant with resistance-type heater elements ...

CONT

Resisto-jets can use a non-reacting propellant(such as water, hydrogen or ammonia) or provide supplemental energy to a chemical propellant, thus increasing its performance(such as a hydrazine thruster which are currently in use on some spacecraft).

French

Domaine(s)
  • Engins spatiaux
DEF

Propulseur utilisant la chaleur fournie par une résistance électrique pour augmenter l'enthalpie des gaz éjectés.

CONT

[Ce genre de propulseur] emploie une résistance chauffante que traverse le fluide avant d'être rejeté. L'impulsion spécifique est de l'ordre de 300 secondes ce qui correspond à un moteur chimique biergol et se situe 30 % au-dessus d'un système à jets de gaz froid. Les resistojets sont déjà opérationnels sur des satellites. Il est question d'en employer sur l'ISS [Station spatiale internationale] (pour les manœuvres) avec en guide de carburant les déchets de la station.

Record 3 2001-04-01

English

Subject field(s)
  • Launchers (Astronautics)
CONT

First launched in 1983, EHT’s offer a nominal specific impulse of 300 seconds compared with 225 seconds for conventional hydrazine thrusters. EHT’s are continuing to be used on numerous satellites such as Iridium.

Record 4 2000-04-01

English

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

The satellite's integral propulsion system uses monomethyl hydrazine and nitrogen tetroxide bipropellant carried in four spherical titanium tanks. A single 490-newton(110-pound force) thruster is used for perigee augmentation and apogee burns, and thirteen 22-newton(5-pound force) thrusters are used for attitude control and stationkeeping maneuvers. Highly accurate antenna pointing control is provided by independent beacon tracking on each of the Ku-band reflector systems. The attitude control system uses an innovative combination of double-gimballed momentum wheels and magnetic field torquing, which minimizes the need for thruster use during normal on-station operations.
