US Patent:

7252046, Aug 7, 2007

Filed:

Dec 8, 2003

Appl. No.:

10/730341

Inventors:

Richard M. Ead - Wakefield RI, US
Robert L. Pendleton - Portsmouth RI, US

Assignee:

International Classification:

B63B 21/16

US Classification:

114254

Abstract:

A free flooded section of an unmanned undersea vehicle (UUV) contains a rotating cylindrical drum, which serves as a spool for a towed line array cable. At the end of the cable is a reverse thruster with the ability to propel itself away from the UUV when the UUV is submerged. The thruster moves away from the UUV, pulling the cable and unspooling it as it does so in order to deploy the array. To recover the array, the cylindrical drum rotates to reel in the cable. The cable is guided through a series of winding guides that allow the cable to be wound evenly on the drum.

International Classification:

B63B 2156

US Classification:

114245

Abstract:

An attitude and roll stabilizer for towed undersea vehicles includes a vertical joining rod having an upper end and a lower end, a roll control weight mounted to the lower end of the vertical joining rod, an attitude control surface mounted to the upper end of the vertical joining rod, a tow rod pivotally mounted transverse to the vertical joining rod, an actuator member connected to the vertical joining rod between the tow rod and the roll control weight, and a connecting bar connecting the actuator adjacent to the aft end of the tow rod. A change in tow speed of the towed vehicle selectively pivots the tow rod about the vertical joining rod, and is correspondingly compensated for with a counteractive pitching of the attitude control surface and the roll control weight, thereby maintaining the level of the towed vehicle at the altered speed.

Abstract:

A very low frequency augmentation system consists of a mobile target very w frequency projector (VLFP) adapted for operation as an augmentation device and installed within a torpedo shell housing. The housing is loaded within the torpedo tube of a submarine. A control and power interface is provided between the housing and the submarine to operate and monitor the augmentation device from the submarine. The housing is loaded in one of the submarine's torpedo tubes and the tube is flooded. The VLFP transmits low frequency vibrations into the surrounding seawater, acting as an augmentor.
