Abstract

A system for the hookup of either a manned or unmanned vehicle with a second vehicle which may be refueling. These vehicles may be both airborne, one airborne and the other on the ground or both on the ground. A probe extending from a first vehicle which may be refueled is joined to a paradrogue or “flycatcher” at the end of a boom on a second vehicle which may be a refueling vehicle. In bringing the probe into the paradrogue an optical sensor on one of the vehicles is employed in conjunction with optical beacons on the other vehicle with the sensor measuring the relative motion between the probe and the paradrogue and generating a control signal for controlling motion of the probe relative to the paradrogue. The positioning of the probe relative to the paradrogue is accurately controlled during the fueling operation by a reeled cable mechanism utilizing a reel which is driven to wind one end of the cable there around to retain the cable in a tensioned state. The other end of the cable is attached to the refueling vehicle . . . The cable, probe and the refueling vehicle are in a triangular configuration while allowing only small interaction forces restrains relative motion between the probe and the paradrogue.

Claims

1. In a system for joining a first vehicle to a second vehicle, said system including a probe mounted on said first vehicle and a paradrogue mounted on said second vehicle, said probe being connected to said paradrogue for connecting said first vehicle to said second vehicle comprising:

means for generating a beam mounted on one of said vehicles;

means for detecting said beam mounted on the other of said vehicles and measuring the relative motion between the probe and the paradrogue;

first means responsive to said detecting means for controlling the relative motion between said probe and said paradrogue; and

second means for controlling the relative motion between the probe and the paradrogue when the probe is within the paradrogue to restrain relative motion therebetween comprising a cable connected to said probe on one end thereof and a reel mounted on said first vehicle, the other end of said cable being connected to said reel, and means for rotatable urging said wheel to tightly wind said cable there around, said cable and said probe forming a triangular configuration with the body of said aircraft.

2. The system of claim 1 wherein said one of said vehicles comprises said first vehicle.

3. The system of claim 1 wherein said one of said vehicles comprises said second vehicle.

4. The system of claim 1 wherein said beam is an optical beam, and the means for detecting said beam is an optical sensor.

5. The system of claim 1 wherein said second vehicle is a ground vehicle and said first vehicle is airborne.

6. The system of claim 1 wherein said probe is mounted on said first vehicle on a universal mount.

7. A system for refueling a first airborne vehicle form a second airborne vehicle, said system including a probe mounted on said first vehicle and a boom mounted on said second vehicle, said boom having a paradrogue mounted on the end thereof, said probe being connected to said paradrogue, fuel being fed from said second vehicle to said first vehicle from said boom to said probe comprising:

at least one beacon mounted on one of said vehicles for generating an optical beam;

a detector mounted on the other of said vehicles for measuring the relative motion between said probe and said boom;

a control system for controlling the relative motion between said boom and said probe in response to the output of said detector; and

a mechanism for controlling the relative motion between the probe and the paradrogue when the probe is within the paradrogue including a cable having one end connected to said boom near one end of said boom, and a reel mounted on said second vehicle, the other end of said cable being connected to said reel, and means for rotatably driving said reel so as to tightly wind said cable there around, the boom and the body of said second vehicle having a triangular configuration.
