Definitions
- This invention relates to deployable countermeasures, and more particularly, to a system for the deployment and retrieval of a towed decoy.
- aerial towed objects are used for a variety of purposes, including decoys, testing, and scientific investigations.
- the decoys are used to draw various types of guided weapons away from an aircraft that the weapons are intended to destroy.
- These towed targets and decoys typically contain various types of electronic circuits to create an apparent target to a weapon in order to attract the weapon to the decoy rather than the aircraft.
- One such active electronic device is a traveling wave tube amplifier equipped transponder to which high voltages must be applied to power its traveling wave tube.
- other controls for the traveling wave tube or other electronics in the towed object are transmitted in one embodiment along a fiber-optic transmission line, which is both fragile and frangible.
- Towed decoys of the type described above are in general sacrificed at the end of the mission, meaning that the towline is cut and the decoy round is lost. Since these decoys are not retrieved, they last for only one mission.
- the typical manner of deployment is such that when a decoy has fulfilled its function, it is simply cut loose.
- the fiber optic wires and the high tension line are severed, with the severing taking place after the high voltage has been removed and after all usable signals along the fiber optic cable have been terminated.
- a towed counter-measure decoy may cost as much as $50,000 per decoy round. As many as eight decoys per sortie or mission can be deployed and as such, assuming 400 sorties per month, then the total expense of deploying expendable decoys is quite large, making the cost for the protection of the aircraft that employs these decoys excessive. Moreover, in a wartime setting, the decoy cannot be manufactured quickly enough. So bad is the situation that it may be necessary to scrounge used decoys from the battlefield where they fall. It will be appreciated that prior to the subject invention, the only type of retrievable devices from aircraft were the sonobuoys that were dropped from helicopters on a line and then winched back up into the helicopter itself.
- Another type of towed device was an air speed head that was used to measure a variety of parameters behind an airplane. These types of devices were winched back into a pod on the aircraft in a conventional manner. In the above examples of winched-in sonobuoys or towed instruments, the instruments were never used in any kind of airborne counter-measure environment. Thus they were not carried in such a manner that they could be rapidly deployed in a battlefield scenario. Certain types of countermeasures were tested using 5-6 foot long test pods. However, the apparatus proved too large and cumbersome for tactical employment.
- IR-guided system initially utilizes radar guidance and then switches over to IR guidance as they come into closer proximity to the target. If one can counter-measure the radar system, then the IR portion can never lock onto the particular infrared target. To do this, the missile is deflected away by generating a signal that causes the radar guidance system in the missile to think that the target is actually elsewhere than it actually is.
- the ALE-50 Towed Decoy system currently in the inventory of the US Armed Forces includes a decoy round in a canister and a reel payout mechanism. When the decoy has served its purpose, it is cut loose and the ALE-50 decoy is lost. Moreover, the same scenario is true for the more modern ALE-55, or in fact, any type of expendable towed vehicle.
- decoys are deployed at the time when a threat is sensed, with the rapid deployment method described herein permitting the decoy to be deployed in seconds, rather than in minutes. This is sufficient time for the decoy to be effective in thwarting an attack. After the threat has ceased, the decoy is retrieved by reeling it in so that it can be deployed again.
- the system contemplates single and multiple cable use, with the deployment system to be described permitting the use of fragile fiber-optic cables and eliminates the necessity of using fiber-optic rotary couplers.
- the fiber-optic cable is wound around a tow cable when the decoy is deployed, with deployment and retrieval done in such a manner that damage to the fiber-optic cable is kept to a minimum.
- deployment or payout of the dual cable system is accomplished through providing both a tow cable and a fiber-optic cable wound around respectively a rotating spindle with a rotationally fixed bail and a rotationally-fixed bobbin with a rotating pickoff.
- the takeoff apparatus which removes the cables from the respective spindle and bobbin is mechanically linked or ganged together such that the payout of the towing cable matches the payout of the fiber-optic cable to prevent cable damage.
- the output of the warning receiver is applied to a control unit which is in turn coupled to a transmission to drive a solenoid braking system for controlling the speed of rotation of the spindle and the pick which rotates with the spindle so as to pick off or unwind the fiber-optic cable carried on the non-rotating bobbin as the bobbin translates back and forth.
- the unwound towline goes through the center of the spindle where the unwound fiber-optic cable meets it and is wound around the tow cable during deployment in a helical fashion.
- the speed at which the tow cable is deployed is controlled by the brake on the spindle, whereas a double helix pick translation mechanism driven by the rotating spindle causes the unwinding of the fiber-optic cable from the bobbin in lock step with the deployment of the towing cable.
- the speed of deployment in terms of how much cable per second exits the canister housing the system is controlled by the braking system for the rotating spindle which houses the tensile member.
- the bail which is utilized to remove the towing cable from the spindle, the bail translates back and forth so that the cable which is helically wound on the spindle is removed in a smooth fashion.
- the pick for removing the fiber-optic cable is translationally fixed, with the translation of the bobbin under the pick achieving smooth fiber-optic cable removal.
- the translation of the bail and the bobbin also serves a level winding function in the retrieval process so as to be able to wind up the respective cables without snagging during the retrieval process.
- the fiber-optic cable is carried on a non-rotating bobbin, there is no necessity for a fiber-optic rotary joint, or other type of dynamic optical interface, to be able to connect control signal generating apparatus to the fiber-optic cable.
- the new re-usable countermeasure system thus provides significant benefits in terms of cost and logistics, while minimizing aircraft installation and performance penalty.
- a fast deployment and retrieval system permits the rapid deployment of a decoy in seconds in response to an incoming threat, thus eliminating the necessity of pre-deployment, with retrieval permitting reeling in and deployment of the decoy round a number of times during a mission in response to threats.
- a controller coupled to a transmission releases a brake that is utilized to control the speed of deployment, whereas upon retrieval, the transmission drives a motor for retrieval of the decoy.
- the system is thus reusable, fast reacting and also minimizes range considerations because the decoy is only deployed when needed.
- the system accommodates both a towing cable and a fiber-optic signal cable in which apparatus for unwinding of the cables, also termed a cable unwinder, is mechanically ganged together so that the cables pay out at the same rate.
- a cable unwinder apparatus for unwinding of the cables
- This type of payout lowers the stress on the fragile fiber-optic cable making possible multiple deployments and retrievals in response to separate threats during a mission.
- a cable winder is employed to retrieve the towing cable and fiber-optic signal cable.
- deployments in seconds versus minutes is accomplished through the utilization of a spindle that carries the tow line and a translating bobbin that carries the fiber-optic cable, with the fiber-optic cable being wound around the tow cable as the dual cables are deployed.
- a bobbin-pick combination stores, deploys and retrieves the fiber-optic cable
- a spindle-bail combination stores, deploys and retrieves the tow cable. The relative speeds between the bobbin-pick combination and the spindle-bail combination are adjusted through a mechanical linkage that gangs together the two mechanisms so that the two cables are deployed at matched payout speeds.
- Figure 1 is a diagrammatic illustration of a tactical situation in which a fighter carrying a full complement of armaments is illuminated by a ground radar for the purpose of launching and intercepting an interceptor missile
- Figure 2a is a diagrammatic illustration of the rapid deployment of a decoy from the illuminated aircraft, the purpose of which is to decoy the missile launched away from th ⁇ aircraft;
- Figure 2b is a diagrammatic illustration of the successful diversion of the interceptor missile from the illuminated aircraft, thus sparing the aircraft;
- Figure 2c is a diagrammatic illustration of the retrieval of the decoy after the threat has been sensed, the decoy deployed and the threat eliminated;
- Figure 3 is a sectional and diagrammatic illustration of one embodiment of the subject invention in which dual cables are utilized in the towing and control of a decoy showing the tow cable deployed around a central spindle and a fiber-optic signal cable deployed about a translatable rotationally-fixed bobbin, with the speed of deployment or retrieval of the cables controlled through the rotation of the spindle which causes the tow cable and the fiber-optic signal cables to be picked off and rewound at matched speeds;
- Figure 4 is a block diagram of the subject system for the deployment of a decoy in response to the output of a warning receiver and the retrieval of the decoy after a threat has passed;
- Figure 5 is a diagrammatic illustration of the retrieval of a previously deployed decoy through a telescopically extended cradle from a canister that originally housed the decoy such that when the decoy is retrieved it is secured to the retractable cradle from whence the decoy may be redeployed in response to another sensed threat;
- Figure 6 is a sectional and diagrammatic view of one embodiment of the subject invention illustrating the spindle/bobbin structure of Figure 3, also indicating a braking solenoid and a transmission for switching between deployment and retrieval of the subject decoy.
- an interceptor missile 20 upon illumination, an interceptor missile 20 is launched at aircraft 10, with aircraft 10 upon sensing the launch of the missile either by direct sensing of the missile launch or by the fact of illumination causes a decoy 22 to be deployed behind aircraft 10 along a cable 24 to a distance which is operative to decoy the launched missile away from its intended target.
- the deployment of the decoy takes seconds as opposed to minutes and can be accomplished through a fast-deployment system involving a rotating spindle from which cable 24 is unreeled at a rapid but controlled rate.
- a fast-deployment system involving a rotating spindle from which cable 24 is unreeled at a rapid but controlled rate.
- interceptor missile 20 explodes away from aircraft 10 due to the action of decoy 22.
- decoy 22 is reeled in or retrieved by aircraft 10 in such a manner that it may be redeployed and thus reused.
- One of the more difficult and more challenging operational scenarios for dual cable systems requires the utilization of a relatively strong towing cable utilized along with a relatively fragile fiber-optic signal cable, with the towing cable being loaded during the deployment and retrieval of the decoy.
- FIG. 3 such a dual cable system is shown in which a towing cable 30 is initially wrapped around a spindle 32 which is rotatably mounted in a housing (not shown in this figure).
- a translating pick or bale 34 translates in the direction of double-ended arrow 36 driven by a double helix drive 38 which is mechanically coupled to a transmission 40.
- the double helix drive 38 revolves at a speed determined by the rotation of spindle 32 as illustrated by mechanical linkage 42 such that cable 30 is either wound or unwound along spindle 32 in a level winding unwinding manner through the utilization of the double helix driven bale.
- spindle 32 rotates as cable 30 is pulled out due to the drag of the decoy once it has been deployed. In one embodiment the deployment is either via mechanical springs or via pyrotechnic launching apparatus.
- spindle 32 When there is tension on cable 30, spindle 32 begins to rotate such that cable 30 moves in the direction of arrow 44 out through the center 46 of spindle 32 and out through the remainder of the spindle driven deployment apparatus such that the cable moves out of the canister housing the spindle and the decoy, again in the direction of arrow 44.
- the tow cable typically is utilized for towing the decoy and is designed to be able to withstand the relative high loads associated during the towing operation.
- the tow cable may also be utilized to house a number of high-voltage lines that are utilized to power the traveling wave tube in a decoy.
- signals In order for the decoy to operate as a counter-measure, signals must be coupled to the decoy and the traveling wave tube and these signals, in one embodiment, are passed over a signal line 50 which, in one embodiment, is a fiber-optic cable.
- fiber-optic cable 50 is initially housed on a rotationally-fixed translating bobbing 52 which is driven by rotating helical grooves 54 which are in a surface 56 of an insert 58 which is press fit into a hollowed out region or cavity 60 of spindle 32.
- spindle 32 is expanded outwardly as illustrated at 62 so as to accommodate translating bobbin 52 in cavity 60, with the expanded portion 62 having a pick 64 comprising a channel 66 in this expanded portion.
- Channel 66 has an orifice 68 which serves as a guide for fiber-optic cable 50 to move in the direction of arrow 70 during the deployment of the decoy.
- Channel 66 is such as to lead the fiber-optic cable through the rotating expanded portion of spindle 32 and out through an orifice 72 from whence it is wrapped around the outgoing tow cable 30 due to the rotation of channel 66 and orifice 72 about cable 30.
- bobbin 52 is secured against rotation and translates as illustrated by double-ended arrow 74 due to the coaction of a cam follower 76 on bobbin flange 78 which coacts with the helical tracks 54 in insert 58.
- cable 50 is drawn outwardly by virtually of its wrapping around cable 30, with the relative rotation of orifice 68 vis a vis bobbin 52 and bale 30 vis a vis spindle 32 being matched in terms of velocity such that, in essence, these two cable dispensing devices are ganged together so that for a close approximation the cables go out at identical speeds.
- Adjustments between the sizes and diameters of the cables and the respective diameters of spindle 34 and bobbin 52 can be taken into account so that the two lines pay out and are returned at the same speed. Thus, during deployment there is very little stress on the fiber-optic cable.
- the fiber-optic cable can be fixedly anchored at one end to the bobbin and thence to electrical drive circuitry, there is no necessity in this embodiment for a fiber-optic rotating joint.
- the spindle 32 reverses its direction and is driven by motor 80 via transmission 40 such that the cables are drawn in both by bale 34 and pick 64 to effectuate a level-winding retrieval process in which the cables are laid down on their respective spindle and bobbin in an even manner to avoid snags.
- the two cables go out at the same speed and come back at the same speed and are level wound in such a manner to make the redeployment of the decoy possible.
- a warning receiver 100 senses a threat and provides an input 102 to a control unit 104 which controls transmission 40 to either actuate a solenoid 106 to control a brake 108 for controlling after launch 110 the rate of deployment of tow cable 30 and signal cable 50 to a decoy 120.
- the rate at which the decoy is deployed is controlled in one embodiment via a velocity detector 122 which is connected via line 124 to control 104 to control brake 108 through transmission 40 and solenoid 106, thus to control the speed of deployment.
- control 104 is coupled to transmission 40 to couple motor 80 to the retrieve spindle 32 which draws the decoy 120 into a cradle 126 due to the aforementioned double helix driven baler and pick described in connection with Figure 3.
- control 104 is coupled to transmission 40 to couple motor 80 to the retrieve spindle 32 which draws the decoy 120 into a cradle 126 due to the aforementioned double helix driven baler and pick described in connection with Figure 3.
- FIG. 5 the entire apparatus for deployment and retrieval of a decoy round is housed, in one embodiment, in a canister 130 which has an extensible or telescoping cradle unit 132 which is used in the retrieval of decoy 120 after the threat no longer exists.
- initially cables 30 and 50 exit canister 130 at an orifice generally indicated at 134 where they are deployed around a sheave 136 and are attached to decoy 120 at an attachment point 140.
- motor 80 drives spindle 32 such that the tow cable and the signal cable are drawn into orifice 134, with sheave 136 resulting in the clamping of the surface of decoy 120 to arms 142 on telescoping cradle 132.
- the result of the retrieval of the decoy is such that the decoy sits in cradle 132 as illustrated by dotted lines 144, ready for redeployment.
- decoy 120 is housed within a compartment within canister 130 below orifice 134.
- motor 80 transmission 40, solenoid 106, brake 108 and the spindle 32/bobbin 52 structure shown in Figure 3.
- a gearing mechanism 150 is utilized to control the speed of the double helix 38 in terms of the rotation 152 of spindle 32.
- spindle 52 is mounted on a cylindrical inner member 152 which is fixedly coupled to canister 130. It is to this cylindrical member that bobbin 52 is translationally mounted but rotationally fixed such that the bobbin only translates but does not rotate.
- spindle 32 is mounted at its distal end to bearings 156 and thus to canister 130, whereas for bale 34 there are a number of pulleys 160, 162 and 164 which guide the tow cable 30 from spindle 32 around and through the center of the spindle, as illustrated.
- What has been described is a system for rapid deployment and retrieval of a towed decoy so that, regardless of the complex nature of the decoy and its drive circuitry and apparatus, the decoy can be safely and rapidly deployed in a matter of seconds and recovered so that it may be used again after the threat has ceased.
