CONTROL OF GYROSCOPE SPIN-UP DEVICES

摘要

A gyroscope and spin-up system in which the gyroscope rotor is rotated by fluid from a spin-up device. Fluid pulses are generated as a result of fluid from the spin-up device striking pulse-generating fluid-receiving areas provided on the rotor. The number of pulses produced depends upon the speed of the rotor. The pulses act on a resonant means which operates at a predetermined rotor speed to cut off the supply of fluid to the spin-up system.
