Filed:

Sep 10, 2009

Appl. No.:

12/557143

Inventors:

Matthew Herbek - Gainesville VA, US
Matthew B. Ascari - Manassas VA, US
John W. Rapp - Manassas VA, US
Robert J. Howard - Clifton VA, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

B63G 8/22

US Classification:

114333

Abstract:

An apparatus includes a housing and a ballast disposed within the housing. The ballast is adapted to receive, store and expel a fluid. A bladder is operatively coupled to the ballast wherein an increase in the volume of the bladder causes a decrease in the free volume of the ballast available for the storage of the fluid therewithin and a decrease in the volume of the bladder causes an increase in the free volume of the ballast available for the storage of the fluid therewithin. A heat exchanger has a heat exchange duct thermally coupled to the bladder and is adapted to receive a fluid from outside the housing. The bladder is configured to receive a clathrate.

US Classification:

114331, 114332, 114333

Abstract:

A buoyancy system includes a chamber having a volume associated therewith, and bladders within the volume of the chamber. Each bladder contains a clathrate mixture in a liquid state. The chamber includes an opening to allow surrounding water to circulate within the volume and contact the bladders. As the chamber is submerged in the surrounding water, the bladders expand based on the clathrate mixture changing from the liquid state to a solid state. This changes buoyancy by allowing less water to circulate within the volume of the chamber.

US Classification:

440 6, 114121, 114333

Abstract:

A water navigable vessel or glider can transport cargo across oceans and other bodies of water without the use of fossil or nuclear fuels. The vessel includes a housing, a cargo or payload area within the housing, one or more control fins attached to the housing, a ballast within the housing, an expandable and contractible container configured to receive a clathrate and maintain a minimum amount of pressure on the clathrate within the housing in proximity to the ballast, and an intake valve coupled to the ballast. The clathrate changes state, thereby changing the buoyancy of the glider, and causing the glider to move through the body of water.

Abstract:

Additive manufacturing of a pipe is disclosed. A lowering mechanism is configured to be coupled with respect to a platform and to lower a pipe through an opening in the platform. An extrusion head is configured to receive material and selectively extrude the material via a nozzle. A gantry is coupled to the extrusion head and is configured to move the extrusion head to an identified location. A controller is coupled to the gantry and configured to direct the gantry to move the extrusion head based on pipe data that identifies a geometry of the pipe. A stabilizer mechanism is configured to maintain the pipe in a desired position during the extrusion of the material.

B32B 27/06

Abstract:

A multiple layer hollow cylinder is provided. An inner air-tight material is wrapped about at least a portion of a mandrel to form a plurality of first material loops. Each first material loop subsequent to an initial first material loop at least partially overlaps a previous first material loop. A resin-infused fabric material is wrapped over the inner air-tight material to form a plurality of second material loops. Each second material loop subsequent to an initial second material loop at least partially overlaps a previous second material loop. An outer air-tight transparent material is wrapped over the resin-infused fabric material to form a plurality of third material loops. Each third material loop subsequent to an initial third material loop at least partially overlaps a previous third material loop. Energy is directed about the outer air-tight transparent material to cure the resin-infused fabric material to form a hollow cylinder.

Abstract:

A cold water pipe assembly, and mechanisms for generating a cold water pipe assembly, are provided. A plurality of mooring lines are secured to a pipe end member. A pipe segment of a plurality of pipe segments is slidably coupled with respect to the mooring lines at a plurality of locations on a pipe wall of the pipe segment. The plurality of pipe segments is iteratively extended to form a pipe assembly of a desired length by joining a next pipe segment to a previous pipe segment to extend the pipe assembly, and lowering the pipe end member and the pipe assembly by extending the mooring lines. At least some of the next pipe segments are slidably coupled with respect to the mooring lines at a plurality of locations on a respective pipe wall of the at least some of the next pipe segments.
