Abstract
A gyroscopic boat roll stabilizer for a boat comprises a gimbal, having a gimbal axis, an enclosure mounted to the gimbal and configured to precess about a gimbal axis, a flywheel assembly rotatably mounted inside the enclosure for generating a torque that is applied to counter a rolling motion of the boat, and a braking system for controlling precession of the enclosure.
Claims9
A gyroscopic boat roll stabilizer configured to be installed in a boat, comprising:
- a gimbal assembly including a support frame and enclosure configured to rotate about a gimbal axis;
- a flywheel assembly rotatably mounted inside the enclosure for generating a torque that is applied to counter a rolling motion of the boat;
- a braking system for controlling precession of the flywheel assembly, the braking system comprising:
- a first hydraulic actuator connected between the support frame and the enclosure and configured to resist precession of the flywheel assembly about the gimbal axis;
- a manifold assembly connected in a fluid flow path to the first actuator;
- the manifold assembly having a main valve;
- wherein the manifold assembly further comprises a hydraulic accumulator communicatively connected to a first output of the main valve.
