Systems and methods for controlling flexible communication links used for aircraft refueling are disclosed. A system in accordance with one aspect of the invention includes a support configured to be carried by an aerial refueling aircraft, and a motion control device carried by the support. A movable aerial refueling boom is positioned proximate to the support and carries an aerial refueling line. A flexible communication link is carried by the boom and is movable with the boom relative to the support. The flexible communication link is coupled to the motion control device wherein the motion control device limits relative motion between the flexible communication link and the support. In particular embodiments, the flexible communication link can include a hydraulic hose or a cable, and the motion control device can include a spring or other forcing member positioned to rotationally urge the flexible communication link toward the support.

The system of claim 2 wherein the motion control device includes a spring arm attached to at least one of the conduit portions to pivot about the pivot axis, and wherein the spring is coupled between the support and the spring arm. 4. The system of claim 1 wherein the flexible communication link includes a first flexible hydraulic hose and a second flexible hydraulic hose, and wherein the motion control device is one of two motion control devices, with each motion control device including: a first generally rigid conduit portion pivotable relative to the support about a generally vertical pivot axis, the first conduit portion having a first coupling site that includes a hydraulic pivot; a second generally rigid conduit portion coupled to the first conduit portion to pivot with the first conduit portion, the second conduit portion extending outwardly from the first conduit portion and having a second coupling site at which one of the flexible hydraulic hoses is coupled; and a spring operatively coupled between the second conduit portion and the support to rotationally urge the second conduit portion toward the support about the pivot axis, wherein each spring urges the respective second conduit portion in opposite directions about the respective pivot axis. 5. The system of claim 1, further comprising a fairing configured to be positioned external to an aircraft fuselage, the fairing housing the motion control device and at least a portion of the flexible communication link. 6. The system of claim 1 wherein the flexible communication link is configured to transmit electromagnetic signals. 7. The system of claim 1 wherein the motion control device includes a generally rigid conduit that is pivotable relative to the support about a pivot axis, and wherein the conduit includes at least two coupling sites proximate to the pivot axis, and at least two coupling sites spaced apart from the pivot axis in opposite directions. 8. The system of claim 1 wherein the support is configured to be fixedly attached to a bulkhead that is fixed relative to the refueling aircraft. 9. The system of claim 1 wherein the motion control device includes a forcing member positioned to urge the flexible communication link toward the support member. 10. The system of claim 1, further comprising the aerial refueling aircraft, and wherein the support is fixedly carried by the aerial refueling aircraft. 11. An aerial refueling system, comprising: a support configured to be carried by an aerial refueling aircraft; a movable aerial refueling boom positioned proximate to the support, the boom carrying an aerial refueling line; a flexible communication link carried by the boom and movable with the boom relative to the support; and control means for controlling motion of the flexible communication link carried by the support, the control means limiting relative motion between the flexible communication link and the support, the control means including a conduit having a passage that receives hydraulic fluid, and further including; at least one of a mechanical spring, a hydraulic spring, and a pneumatic spring. 12. The system of claim 11 wherein the control means has a first coupling site and a movable second coupling site, and wherein the flexible communication link is attached to the second coupling site. 13. The system of claim 11 wherein the control means urges the communication link toward the support. 14. The system of claim 11 wherein the control means applies a tension to the communication link. 15. The system of claim 11, further comprising the refueling aircraft, and wherein the support is attached to the refueling aircraft. 16. A method for operating an aerial refueling system, comprising: moving an aerial refueling boom carried by an aerial refueling aircraft relative to the aerial refueling aircraft; moving a flexible communication link carried by the boom along with the boom as the boom moves relative to the aircraft, the flexible communication link including a hydraulic hose; and controlling a motion of the flexible communication link relative to the aircraft by applying a force on the flexible communication link separate from a force applied to move the boom to at least restrict contact between the flexible communication link and fixed portions of at least one of the aircraft and the boom. 17. The method of claim 16 wherein controlling a motion includes controlling a motion of a communication link configured to carry electromagnetic signals. 18. The method of claim 16 wherein controlling a motion includes urging the communication link toward a fixed portion of at least one of the boom and the aircraft. 19.
