The aerodynamic table is designed to ensure the free movement of the studied objects in the horizontal plane with minimal friction. It is a precision aluminum horizontal surface with a uniform grid of holes, through which air from an external fan is supplied under pressure. Air pressure allows you to hold a load on an air cushion - one or more mock-ups of moving objects.

The table is used in laboratory conditions and is intended for:

  • working out algorithms for controlling the motion of the center of mass of spacecraft: tasks of autonomous navigation, control of onboard propulsion systems, operation of ADCS;
  • studying the motion control algorithms of a group of microsatellites intended for conducting spatial studies of near-Earth space, as well as technological experiments in orbit. The latter include experiments on autonomous relative navigation, distributed orbital computing systems, inter-satellite communications, the operation of cable systems, automatic inspection and docking, and other tasks related to these topics.

 

*On video previous version of aerodynamic table is used.

The aerodynamic table is able to simulate free movement without friction in the horizontal plane of one or several models of small-sized mobile objects, for example, microsatellites, weighing up to 10 kg each; determine the parameters of their movement using an independent measurement system.
