Record 2 2010-10-04

English

Subject field(s)
  • Spacecraft
  • Launching and Space Maneuvering
DEF

A momentum transfer and storage device in which a wheel is driven by an electric motor.

OBS

The motor torque transfers the momentum from the main body of the spacecraft to the wheel.

OBS

Such devices are particularly suitable for correcting cycling disturbing torques and are also used to provide very accurate torque control.

PHR

Reaction wheel off-loading.

French

Domaine(s)
  • Engins spatiaux
  • Lancement et manœuvres dans l'espace
CONT

Les essais d'endurance des roues à inertie et à réaction [...] se sont poursuivis favorablement.

OBS

L'acronyme RW est spécifique à RADARSAT.

Subject field(s)
  • Navigation Instruments
  • Spacecraft
OBS

gimballed momentum wheel : Better attitude control and energy storage can be achieved by using a pair of counter-rotating micro wheels. This configuration enables micro-satellites to change their angular momentum and orientation with very little net change in stored energy. Likewise, energy can be extracted or added to a pair of wheels without changing the satellite's attitude. Power can be saved while using a regenerative brake state to decrease the speed, or this braking energy can be used to accelerate the other micro-wheel rotating in the opposite direction in a gimballed momentum wheel. Thus, it can sustain spacecraft with limited power during a short-term space mission.

Record 4 2001-08-27

English

Subject field(s)
  • General Mechanics (Physics)
  • Aircraft Piloting and Navigation
  • Navigation Instruments
  • Flight Instruments and Equipment (Aeroindustry)
CONT

Momentum wheels are capable of providing gyroscopic stiffness in more than one axis. These wheels provide a nominally constant angular momentum to provide angular stiffness. The mean disturbance torque typically determines the momentum storage of reaction wheels and momentum wheels over one half an orbit.

French

Domaine(s)
  • Mécanique générale (Physique)
  • Pilotage et navigation aérienne
  • Instruments de navigation
  • Instruments et équipement de bord (Constructions aéronautiques)
CONT

Dans une même famille de [gyromètres], les grandeurs suivantes sont généralement fixées : moment cinétique; moment d'inertie; débattement. Par contre, la raideur angulaire peut être choisie, pour chaque appareil, dans certaines limites. [...] Le rappel élastique peut être obtenu par voie mécanique ou électrique.
