Abstract
A split cylinder compliant tube baffle for absorbing and/or canceling noise signals generated within a submarine or surface ship is described. The split cylinder tube baffle includes an air-filled tube having a longitudinal gap extending the length of the tube. The baffle further comprises a rubber jacket for enclosing the gap and end covers for sealing end portions of the tube. A split tube baffle assembly is generally constructed of tube baffles adjacently aligned to form a panel. The panels can then be stacked for increased attenuation of acoustic signals. The split cylinder baffle offers significant size reduction and improved performance over conventional compliant tube baffle designs.
Claims18
A baffle comprising:
- a hollow tube having a length, end portions, and a longitudinal slot extending the length of the tube;
- means for sealing the slot of said tube;
- and
- means for enclosing the end portions of the tube.
A baffle assembly comprising:
- a plurality of hollow cylindrical tubes, each one of said plurality of tubes having a length, end portions, and a longitudinal slot extending the length of the tube wherein the plurality of tubes are aligned adjacently to one another;
- and
- means for sealing the gap of each one of said plurality of tubes;
- and
- means for enclosing the end portions of each one of said plurality of tubes.
A baffle assembly comprising:
- a panel comprising:
- a plurality of hollow cylindrical tubes, each one of said plurality of tubes having a length, a pair of end portions, and a longitudinal slot extending the length of the tube wherein the plurality of tubes are aligned adjacently to one another;
- a pair of endcovers disposed over the pair of end portions of each of said plurality of tubes;
- a rubber seal disposed over the slot of each one of said hollow tubes, wherein the seal has a looped portion extending into the gap of each one of said tubes.
The baffle assembly comprising:
- a plurality of panels each panel comprising:
- a plurality of hollow cylindrical tubes, each one of said plurality of tubes having a length, end portions, and a longitudinal slot extending the length of the tube wherein the plurality of tubes are aligned adjacently to one another and the slots of the plurality of tubes are randomly aligned relative to each other;
- a pair of endcovers disposed over the pair of end portions of each of said plurality of tubes;
- a rubber seal disposed over the slot of each one of said hollow tubes, wherein the seal has a looped portion extending into the slot of each one of said tubes.
A baffle surrounded by a fluid medium, said baffle comprising:
- a hollow tube having a longitudinal slot, said tube being disposed in contact with said surrounding fluid medium.
