Spacecraft reaction wheels

Web28. apr 2024 · One advantage with RWs is that the maximum torque of a wheel can be regarded as nearly constant along its fixed spin axis. Unlike CMGs or magnetic torque rods, an RW can generate consistent torques regardless of the attitude and slew rate of the spacecraft as long as the RW speed is within its operational range. WebSpacecraft reaction wheel maneuvers are limited by the maximum torque and/or angular momentum that the wheels can provide. For an n-wheel configuration, the torque or momentum envelope can be obtained by projecting the n-dimensional hypercube, representing the domain boundary of individual wheel torques or momenta, into three ...
