Section 6: GYRO SPECIFICATIONS
Operator Controls
An Operator’s Display is provided to start, operate, monitor, and shutdown the Gyro.
Performance
Gyro reduction of boat roll is a function of the boat’s displacement, transverse metacentric height (GM
T
)
and hull damping as well as the operating conditions (speed and heading with respect to waves) and sea
state. The Gyro controller regulates the active hydraulic brake to ensure the Gyro’s anti ‐ roll torque is
maximized irrespective of hull characteristics or operating conditions. In heavy seas, the Gyro rpm may
droop when the required power exceeds 2500 watts – this is normal and is designed to limit large power
demands at the expense of a small loss of performance
Alarm and Monitoring
Sensors, alarms and shutdowns are provided to allow unattended operation. Sensors measure flywheel
bearing temperatures, motor and drive temperatures, vacuum pressure, gimbal angle, brake pressure,
and ship motion. The Gyro controller sends sensor values and alarm information to the display and also
locks the brake and shuts down the motor drive in the event of an alarm condition. Gyro operating
history during faults or alarms is recorded in the controller’s memory for subsequent recall if service is
needed.
Safety
The brake automatically locks the Gyro so it cannot generate excessive anti ‐ rolling torque loads in the
event of a system fault or alarm, loss of electrical power or loss of brake pressure. The brake can be
locked from the Display or by shutting off power locally at the Motor Drive Box or Gyro Control Box.
