The first type of gyroscopic instrument to successfully reduce gimbal bearing friction to an acceptable level for precision applications was the floated gyroscope. In this instrument the rotating member is sealed within a hollow cylinder which forms the inner gimbal of the gyro. This is mounted in the gyro case whith a fluid surrounding the cylinder; the density of the fluid is chosen so as to exactly float the cylinder, thus removing the weight of the inner gimbal from the bearings and greatly relieving the bearing frictional load. 2, record 2, English, - floated%20gyroscope

... AlliedSignal has changed the way it manufactures its highly accurate gyros in an effort to stretch their service lives to prevent a future shutdown. But the basic design of the gyros has not changed, since they are about twice as accurate as the next-best gyros available, according to Hubble Program Manager John Campbell. The problem is the tiny leads that carry power to the gyro rotors. Sunk in a thick damping fluid, the hair-like wires corrode over time and break. The six new gyros Discovery's crew will install retain the fine power leads, but the damping fluid was loaded into the gyros in a manner that engineers hope kept oxygen out of the system, reducing the risk of oxidation. 5, record 3, English, - damping%20fluid

Another important property for liquids and gases is viscosity. The absolute viscosity (symbol µ) measures the force needed to flow the liquid or gas at a certain speed. High viscosity liquids will require more force to move at some speed than low viscosity liquids. Think of honey (a high viscosity liquid) and water (a low viscosity liquid). If you were to push your hand through a bowl of honey, it would require more force than pushing your hand through a bowl of water (at the same speed). The viscosity decreases with increasing temperature. 2, record 4, English, - high%2Dviscosity%20liquid

The "dynamic tuning" of a dynamically tuned gyroscope (DTG) refers to a clever gimbal configuration that balances the torques from the support flexure with dynamic spring torques created by gimbal "flutter" while the gyro rotor spins. This configuration allows the gyro rotor to spin to a "free" rotor in two axes. 2, record 5, English, - dynamically%20tuned%20gyro

By drawing an analogy between linear and rotational dynamics, an equation describing the viscous torque acting on an object rotating in a fluid can be anticipated. Stokes' and Newton's models of a viscous drag force are commonly used to describe the damping force acting on an object moving linearly through a fluid. This experiment demonstrates that these models can be extended to describe the viscous torque that damps the rotation of an object in a fluid. When the rotating object is round, the fluid flow is laminar; hence, the viscous torque is proportional to the angular velocity to the first power, analogous to Stokes' model. However, when the rotating object is rough, causing the fluid flow to be turbulent, the viscous torque is proportional to the angular velocity to the second power, analogous to Newton's model. In addition, this experiment demonstrates that the proportionality constant between viscous torque and angular velocity is dependent on the shape of the object, as is the case in both Stokes' and Newton's models. 1, record 6, English, - viscous%20torque

Mercury flotation. The directive force of any gyrocompass is small when nearly on the meridian. It is therefore necessary to suspend it in as nearly a frictionless support as possible. This is accomplished by supporting the sensitive element on a hollow steel sphere which floats in a concentric tank of mercury... The sphere should clear the bottom of the tank by 3/16 in. For convenience in checking this position, a line has been placed on the contact support tube. This line is level with the topmost surface of the sensitive element when the flotation is correct. 3, record 7, English, - flotation

Inverted gyroscopic pendulum. A cradle freely rotating around a horizontal axis rests on a stop. It supports a motor-reduction gear which is used to tilt a gyroscopic spinner (with a kinetic momentum of 10 Nms) around its diameter. The tilt angle control law brings the cradle to an equilibrium position (centre of gravity of the moving assembly above the rotation axis). 1, record 9, English, - moving%20assembly

A single-degree-of-freedom gyro having primarily viscous restraint of its spin axis about the output axis; an output signal is produced by gimbal angular displacement, relative to the base, which is proportional to the integral of the angular rate of the base about the input axis. 5, record 10, English, - rate%20integrating%20gyro
