The primary reason the rotor disk follows the ship deck is because the swashplate stays aligned to the deck, and the rotor disk follows the swashplate. Disconnect the pitch links and the rotor...

From a physics standpoint, a "gyro" can be defined as an object whose effects due to rotational motion dominate the behavior of the object. In this regard, a rotor is a gyro because the effects of...

Gyros and rotors both obey the same fundamental laws of physics that perfectly describe their behavior. F=MA applies equally to both. The differences lie in the forces that exist and where they get...

There are subtle effects that can result in a teetering rotor from producing exactly 90 deg phase lag. For example, any of the following will result in a deviation from an exact 90-deg phase lag:
-...

The reason a gyro precesses at 90 deg while some rotors exhibit phase lag less than 90 deg is because rotors with hinge offset (or effective hinge offset) inject an additional moment into the disk...
