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 .
Gyroscopic control may refer to: Control moment gyroscope , an attitude control device generally used in spacecraft attitude control systems Gyroscopic control (gaming) , accelerometers to as a control input
Classically, a gyroscope consists of a spinning mass, but there are also "ring laser gyros" utilizing coherent light reflected around a closed path. Another type of "gyro" is a hemispherical resonator gyro where a crystal cup shaped like a wine glass can be driven into oscillation just as a wine glass "sings" as a finger is rubbed around its ...
For example, the spinning rotor may be suspended in a fluid, instead of being mounted in gimbals. A control moment gyroscope (CMG) is an example of a fixed-output-gimbal device that is used on spacecraft to hold or maintain a desired attitude angle or pointing direction using the gyroscopic resistance force.
The control could also be used to help point the instruments. [82] The gyroscopes took about ten hours to get spun up if they were turned off. [83] There was also a thruster system to control Skylab's attitude. [83] There were 9 rate-gyroscope sensors, 3 for each axis. [83] These were sensors that fed their output to the Skylab digital computer ...
The control panel for the Minneapolis-Honeywell C-1 gyroscopic autopilot, used on B-24 bombers. The gyroscopic autopilot was a type of autopilot system developed primarily for aviation uses in the early 20th century. Since then, the principles of this autopilot has been the basis of many different aircraft control systems, both military and ...
I have just modified 4 external links on Control moment gyroscope. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
Demonstrated shuttle thermal protection repair techniques and enhancements to the Station's attitude control system. installed a base and cabling for an External Stowage Platform, rerouted power to Control Moment Gyroscope-2 (CMG-2), retrieved two exposure experiments, and replaced a faulty global positioning system antenna on the station.
