Gyroscopic roll stabilizer for boats

摘要

A gyroscopic roll stabilizer for a small boat. The stabilizer includes a flywheel, a flywheel drive motor configured to spin the flywheel about a spin axis at a tip speed of at least 450 ft/sec, a gimbal structure configured to permit flywheel precession about a gimbal axis, and a device for applying a torque to the flywheel about the gimbal axis. The flywheel and gimbal structure are configured so that when installed in the small boat the stabilizer damps roll motion of the boat.
