  • Retractable bow diving plane for a submarine
    Patent number: 5467728
    Abstract: A retractable bow diving plane is provided which can be rotated when fully xtended or retracted or when at any position in between, and which allows for independent operation of the port and starboard bow diving planes. The major assemblies for each plane are a large rotor bearing, four rotational hydraulic cylinders, and an extension and retraction hydraulic cylinder assembly. The plane is engaged in a slot in the middle of the rotor bearing. This rotor bearing supports the plane, rotates the plane, and allows the plane to move through the slot for extension and retraction.
