Abstract

A submarine has a vertical stabilizer providing a chamber in which is rotbly mounted a reel for rotation about an athwartships axis. One of the side elements of the reel has an engageable surface adjacent its periphery, and a drive motor in the stabilizer is engaged with the engageable surface of the one side element to effect rotation of the reel. An elongated cable is coiled about the hub of the reel and extends outwardly of a passage extending to the aft end of the stabilizer. A mechanism inside in the vertical stabilizer guides the cable between the passage and the storage space to facilitate coiling of the cable on to the reel and for deploying the cable therefrom. A brake mechanism is used to prevent the reel against rotation to prevent further either deploying or coiling of the cable. A driving mechanism controls the rate of deploying of the cable.

Claims

1. In a submarine having a plurality of horizontal stabilizers, a vertical stabilizer towed array handling system combination comprising:

a vertical stabilizer secured to one of said plurality of horizontal stabilizers and providing a chamber therewithin, said stabilizer having a passage extending inwardly from an aft end thereof into said chamber;

a reel rotatably mounted in said chamber for rotation about an athwartships axis, said reel having a hub element and a pair of side elements defining a storage space therebetween, one of said side elements having engageable means thereon adjacent its periphery;

drive means in said vertical stabilizer engageable with said engageable means of said one side element to effect rotation of said reel;

an elongated cable coiled about said hub in said storage space and extending outwardly of said passage;

guide means in said stabilizer for guiding said cable between said passage and said storage space to facilitate coiling said cable onto said reel and for deploying it therefrom;

releasable means for locking said reel against rotation; and

control means for said drive means.

2. The combination in accordance with claim 1 wherein said engageable means is disposed about a circumferential edge of said one side element.

3. The combination in accordance with claim 2 wherein said drive means includes a motor disposed with its shaft extending parallel to an axis of rotation of said reel.

4. The combination in accordance with claim 3 wherein said engageable means comprises gear teeth formed in the circumferential edge of said one side element and the shaft of said drive motor has a gear thereon which is engaged therewith.

5. The combination in accordance with claim 1 wherein an outer side element of said reel provides a portion of the outer side surface of said vertical stabilizer.

6. The combination in accordance with claim 1 wherein there is included a slip ring assembly for said reel and said cable has an inner end portion extending through said hub and into said slip ring assembly.

7. The combination in accordance with claim 1 wherein said vertical stabilizer has a removable access element in its periphery to provide access to said drive means.

8. The combination in accordance with claim 1 wherein said guide means controls tension on said cable to facilitate deployment and coiling of said cable.

9. In a submarine having a plurality of horizontal stabilizers, a vertical stabilizer towed array system combination comprising:

a vertical stabilizer secured to one of said plurality of horizontal stabilizers and providing a chamber therewithin, said stabilizer having a passage extending inwardly from an aft end of said vertical stabilizer into said chamber;

a reel rotatably mounted in said chamber for rotation about an athwartships axis, said reel having a hub element and a pair of side elements defining a storage space therebetween, one of said side elements having engageable means thereon disposed about a circumferential edge of one of said side elements, an outer side element of said reel providing a portion of an outer side surface of said vertical stabilizer;

drive means in said vertical stabilizer engageable with said engageable means of said one side element to effect rotation of said reel, said drive means including a motor disposed with its shaft extending parallel to an axis of rotation or said reel;

an elongated cable coiled about said hub in said storage space and extending outwardly of said passage;

guide means in said stabilizer for guiding said cable between said passage and said storage space to facilitate coiling said cable onto said reel and for deploying it therefrom;

releasable means for locking said reel against rotation; and

control means for said drive means.

10. The submarine in accordance with claim 9 wherein said engageable means comprises gear teeth formed in the circumferential edge of said one side element and the shaft of said drive motor has a gear thereon which is engaged therewith.

11. The submarine in accordance with claim 9 wherein there is included a slip ring assembly for said reel and said cable has an inner end portion extending through said hub into said slip ring assembly.

12. The submarine in accordance with claim 9 wherein said vertical stabilizer has a removable access element in its periphery to provide access to said drive means.
