Centrifugal gyroscopic devices, and associated systems and methods

A method of operating a centrifugal gyroscopic device, the method comprising:

• rotating a shaft of the centrifugal gyroscopic device about a first axis;
• pivoting an arm of the centrifugal gyroscopic device about a second axis different from the first axis, wherein the arm is pivotably coupled to the shaft and configured to rotate with the shaft;
• pivoting at least one rotor of the centrifugal gyroscopic device about a third axis different from the first axis and different from the second axis, wherein the at least one rotor is pivotably coupled to the arm and configured to pivot with the arm about the second axis;
• and
• controlling the rotating of the shaft, the pivoting of the arm, and/or the pivoting of the at least one rotor to bring the arm and the at least one rotor into a mode of operation in which (a) the arm oscillates about the second axis at a first frequency and (b) the at least one rotor oscillates about the third axis at a second frequency at least approximately equal to the first frequency.

A centrifugal gyroscopic device, comprising:

• a spindle rotatable about a first axis;
• an arm coupled to the spindle and configured to rotate with the spindle, wherein the arm has a first end portion and a second end portion opposite the first end portion, wherein the arm is pivotable about a second axis different from the first axis, and wherein the first axis is orthogonal to the second axis;
• a first rotor coupled to the first end portion of the arm;
• a second rotor coupled to the second end portion of the arm, wherein the first rotor and the second rotor are each pivotable about a third axis different from the first axis and different from the second axis;
• and
• a control system operably coupled to at least one of the shaft, the arm, the first rotor, and the second rotor, wherein the control system is configured to bring the arm, the first rotor, and the second rotor into a mode of operation in which (a) the arm oscillates about the second axis at a first frequency and (b) the first rotor and the second rotor oscillate about the third axis at a second frequency at least approximately equal to the first frequency.
