A Bearing Cartridge Assembly for Longterm Performance of Momentum/Reaction Wheels used in Spacecraft

A Bearing Cartridge Assembly for Longterm Performance of Momentum/Reaction Wheels used in Spacecraft

Momentum/reaction wheels are used in a spacecraft for the attitude control. They are used for the real time control of spacecraft attitude towards the desired direction as required by the mission. These are one of the few systems of a spacecraft which need to work continuously from the beginning to...
