A control moment gyroscope (CMG) is an attitude control device generally used in spacecraft attitude control systems. A CMG consists of a spinning rotor and one or more motorized gimbals that tilt the rotor’s angular momentum. As the rotor tilts, the changing angular momentum causes a gyroscopic torque that … See more CMGs differ from reaction wheels. The latter apply torque simply by changing rotor spin speed, but the former tilt the rotor's spin axis without necessarily changing its spin speed. CMGs are also far more power efficient. For … See more Single-gimbal The most effective CMGs include only a single gimbal. When the gimbal of such a CMG rotates, the … See more Skylab Skylab, launched in May 1973, was the first manned spacecraft to be fitted with large CMGs for … See more CMG applications and fundamental research are undertaken at several institutions. • Georgia Tech's Panagiotis Tsiotras has studied variable-speed CMGs in connection with flywheel energy storage and has built a … See more Singularities At least three single-axis CMGs are necessary for control of spacecraft attitude. However, no matter how many CMGs a spacecraft … See more • Anti-rolling gyro, a system that stabilizes roll motion in ocean-going ships • Reaction wheel • Skylab, a space station using CMGs See more WebThe CMG process parameters, including pressure, workpiece speed and wheel speed, were optimized by using orthogonal experimental method. The surface roughness can reach 0.461nm in Ra on the basis of optimized processing parameters.
