PURPOSE: A variable speed gimbal control moment gyro is provided to generate the torque of a three dimensional direction for controlling the posture of an aerospace vehicle by variably controlling the rotational speed of a flywheel. CONSTITUTION: A variable speed gimbal control moment gyro comprises a flywheel(110), a flywheel driving machine(120), a first gimbal unit(130), a second gimbal unit(140), and a flying object platform(150). The flywheel stores angular momentum. The flywheel driving machine varies the rotation speed of the flywheel. The first gimbal unit is connected to the flywheel driving machine, and rotates the flywheel driving machine to a first rotation direction based on a first gimbal rotary shaft crossing with a rotary shaft of the flywheel at a right angle. The second gimbal unit is connected to the first gimbal unit, and rotates the first gimbal unit to a second rotation direction based on a second gimbal rotary shaft crossing with the first gimbal rotary shaft of the first gimbal unit. The flying object platform is connected to the second gimbal unit and receives reaction torque generated the change of the angular momentum of the flywheel.
