  • Gyro monorail — The gyro monorail, gyroscopic monorail, gyro stabilized monorail, or gyrocar all denote a single rail land vehicle, road or rail, which uses the gyroscopic action of a spinning wheel, which is forced to precess, to overcome the inherent inverted… …   Wikipedia

  • gyro wander — The undesired movement of a spin axis from its original position. Gyro wander can be apparent or real. Apparent gyro wander is the result of the movement of the earth and is as shown in the illustration. Real wander can result from mechanical… …   Aviation dictionary

  • gyro — i. A device that utilizes the angular momentum of a spinning mass (rotor) to sense the angular motion of its base about one or two axes orthogonal to the spin axis. Also called a gyroscope. This definition does not include more complex systems… …   Aviation dictionary

  • vertical gyro — A two degree of freedom gyroscope with provision for maintaining its spin axis vertical. Output signals are produced by a gimbal angular displacement that corresponds to the angular displacement of the base about the two orthogonal axis. It is… …   Aviation dictionary

  • free gyro — i. A two degree of freedom gyro whose spin axis can be oriented in any specified attitude. In a free gyro, output signals are produced by the gimbals’ angular displacements that correspond to components of the angular displacement of the base. ii …   Aviation dictionary
