Abstract:

A rotary positioning module (RPM) for a paravane for use in connection with cable or hose towed from a towing platform through a towing medium. The RPM includes a stationary portion and a rotational portion, The stationary portion is adapted to be attached to the cable or hose, and includes a plurality of electrically-energizable field windings symmetrically positioned around the cable or hose, The rotational portion is rotatably mounted around the stationary portion for controlling orientation of rotary positioning module wings attached thereto as it is being towed through the towing medium to facilitate the positioning of the cable or hose in a towed array. The rotational portion includes a plurality of permanent magnets symmetrically positioned around the stationary portion in proximity to the field windings of the stationary portion and a rotary position sensor. The rotational position sensor senses the angular position of the rotational portion relative to the stationary portion and enables a controller on a towing platform to control the electric current to the field windings to facilitate the angular positioning of the rotational portion in relation to the stationary portion.

International Classification:

H01Q 300

US Classification:

343766

Abstract:

There is presented an antenna assembly comprising an elongated mast slida mounted in a support structure. A first electric motor is disposed at a proximal end of the mast for moving the mast along the axis of the mast, and a second electric motor is disposed at a distal end of the mast for moving the mast rotatively about its axis.

International Classification:

B63R 2104

US Classification:

114242

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.

International Classification:

B63B 2148

US Classification:

114311

Abstract:

The drogue of the present invention induces drag for a plurality of underer tow lines. A tail section is axially movable within a nose section and extends partially therefrom. A tow line passes through the nose section and is coupled to the tail section. A rod is fixed to the nose section and extends through and axially away from the nose section into the tail section. A spring couples the nose section to the tail section such that the spring is placed in tension when the tail section and nose section are caused to move axially towards one another. In turn, the nose section and tail section are caused to move axially away from one another when the spring is allowed to relax. Drag wings mounted on the tail section are movable between a first minimal drag position and a second maximum position. Movement of an actuator mounted in the tail section causes corresponding movement of the drag wings between the first and second position. An engagement mechanism supported on the rod's aftmost end engages and moves the actuator in correspondence with movement of the spring.

US Classification:

114254

Abstract:

A combination winch and stowage reel assembly for arrays towed by submari, the assembly comprising a hub, a slip ring mounted in the hub and in communication with a receiver in the submarine, a reel rotatably mounted on the hub, the reel having gear teeth on a periphery thereof, a tow cable fixed to the reel and adapted to have attached to a free end thereof an array to be towed behind the submarine, the tow cable being in communication with the slip ring to form a communication path including the array, the tow cable, the slip ring and the receiver, a drive gear engaged with the reel gear teeth, and a motor for turning the drive gear, thereby to turn the reel on the hub to pay out and take up the cable.

International Classification:

H02P 602

US Classification:

318254

Abstract:

An electric drive system that is used in submarines, for powering or contling towed arrays handling systems and other machinery, which has at least one submersible brushless direct current motor whose operation is monitored and regulated by a 6-step variable bus motor controller receiving command signals from a control and indicator unit. The controller receives, in addition to the command signals for the operation of the motor from the control and indicator unit, signals indicative of the rotational velocity of the motor from the motor itself. The controller comprises a servo-mechanism unit that compares the two signals and adjusts the speed of the motor in compliance with the command signals from the control and indicator unit.
