Gyro rotor

Use Balance weights for aircraft, high-speed rotors in gyro-compasses, y-radiation shielding, radio-isotope transportation casks and fuel element transfer casks, in general as structural material applicable to radiation shielding. [Pg.1304]

Fig. 5.10.1 Schematic drawing of a rotational disc gyro. The rotor (in blue) is oscillating around the z axis, driven by fixed comb structures. A yaw rate around the y axis generates a Coriolis force in the z direction. The resulting seesaw-like out-of-plane motion of the rotor is detected by measuring the difference in capacities between the rotor and detecting electrodes beneath it...

Obviously, this gyro design requires tightly controlled surface micromachining processes with respect to the thicknesses of the polysilicon and sacrificial layers and to stress gradients within the polysilicon rotor. However, the tolerance band widths and process capability indices available for these model parameters were not indicative of significant yield losses in a factorial analysis. [Pg.227]

A syncho consisted of a static element (the Stator) and a rotating element within it (the rotor). Within the IRU, a field is set up in each of the three legs of the stator. This is as a result of the relative angle (pitch) of the Gyro connected to the Rotor... [Pg.14]

The development of inertial guidance systems depends on finding methods to eliminate all unpredictable forces from the inertial element. In the gyro field, engineering techniques have been pushed almost to the limit in the design of mechanical rotor supports that minimize friction. A promising alternative to mechanical suspension is the use of the pressures exerted by electromagnetic fields. [Pg.95]
