Ion Thruster Gimbal
Moog developed a gimballing mechanism designed to provide thrust vectoring with limited range of motion for Hayabusa’s Ion thrusters compatible with electric propulsion technology. The amount of mass the gimbal is designed to carry from Earth to space is significantly large compared to the allocated weight budget of the gimbal.
Key Features:
- Light weight
- 15 year on-orbit design life
- High resolution and accuracy
- Dual axis gimbal actuated by linear actuators for cross axis positioning capabilities
- High reliability space qualified stepper motor’s with lead-screw actuation for positioning
