Gimbal

The satellite gimbal is a system that provides the suspension of the satellite in laboratory conditions, within the Earth's gravity field. It is like a physical pendulum using special fasteners. The gimbal provides an elastic rotation of the satellite model relative to the gimbal axis in the horizontal plane.

The gimbal is a sufficiently strong, elastic thread of great elongation (the ratio of its length to the diameter »1), which has an attachment (built-in) on one side to the satellite model and on the other side to the power frame under the ceiling of the room in which the experiment is conducted. The length of the thread can be from 1 to 2 meters (to be able to accommodate in a room with reasonable requirements for ceiling height). The gimbal provides a simple control of the length of the thread within this range by one person with an accuracy of not worse than 1 cm.

The main parameters of the thread:

  • carrying capacity not less than 10 kg;
  • maximum torque when twisting per turnover with a minimum thread length - no more than 0.005 Nm;
  • maximum angle of twist: + -360 degrees;
  • maximum elastic elongation with the maximum load - no more than 1%;
  • number of cycles of spin-up - not less than 20 thousand;
  • slight change in characteristics with time and temperature when working in laboratory conditions (temperature +18 .. +25 C, moisture 50..95%, normal pressure).
